313 series

View on Grokipedia
from Grokipedia
The 313 series (313系, san-ichi-san-kei) is a family of direct current (DC) suburban electric multiple units (EMUs) operated by Central Japan Railway Company (JR Central) across its conventional lines in Japan's Chūbu region. Introduced on May 6, 1999, the series was developed as a versatile replacement for aging Japanese National Railways-era stock, including the 113, 115, 117, 119, 123, and 165 series trains, to serve both high-density commuter routes and rural services. With a total of 539 cars built between 1999 and 2014 (plus additional units in 2019), it remains a mainstay of JR Central's fleet, often forming 2- to 6-car sets that can be coupled into longer consists of up to 10 cars. The design of the 313 series draws from the limited-express 373 series, emphasizing adaptability for all electrified lines in JR Central's network while excluding non-electrified routes. Key variants include the 1000 and 1300 subseries for standard commuter operations with longitudinal bench seating; the 2000 series for transverse seating on regional lines; and specialized types like the 8000 variant, originally for premium reserved-seat services such as the Central Liner (Nagoya to Nakatsugawa) but later reallocated to Shizuoka-area routes in 2022. All variants feature three doors per side per car, LED lighting in later builds, and options for semi-automatic doors or LCD monitors in select units, enhancing efficiency on busy urban corridors like the Tokaido Main Line and rural branches such as the Iida Line. Recent enhancements, including in-car security cameras installed starting in fiscal year 2024 on trains serving Nagoya Station, reflect ongoing improvements for passenger safety. Operationally, the 313 series supports a wide array of services, from rapid commuter relief in the Nagoya area to unstaffed rural runs without conductors, and even special events like bicycle-friendly "cycle trains" on the Tokaido Main Line using two-car sets with long seats for easier boarding. Its ubiquitous presence—often paired with newer 315 series trains in 6-car formations—has made it integral to daily travel in Nagoya and Shizuoka. The series' enduring role underscores JR Central's focus on reliable, multi-purpose suburban railroading.

Overview

Description

The 313 series is a family of stainless steel-bodied DC electric multiple units (EMUs) operated by Central Japan Railway Company (JR Central) since their introduction in 1999. These trains serve as the standard type for conventional line services, replacing older models such as the 113 and 115 series on electrified routes in the region. Designed for cost-effectiveness and versatility, the series features lightweight construction with a steel front end, enabling efficient operation on suburban and regional networks. Key operational parameters include a maximum operating speed of 120–130 km/h, supported by VVVF inverter control systems and lightweight bolsterless bogies for smooth performance. Acceleration and deceleration rates are optimized for urban and intercity travel. The single-arm pantograph design on powered cars ensures reliable current collection on 1.5 kV DC overhead lines. Dimensions vary slightly by car type, with end cars measuring 20,100 mm in length, 2,978 mm in width, and 4,020 mm in height, promoting compatibility across JR Central's infrastructure. A total of 541 cars were built between 1999 and 2019 by major manufacturers including Nippon Sharyo, Kinki Sharyo, Tokyu Car Corporation, and Hitachi, forming sets of 2 to 6 cars that can couple for longer formations. These units are primarily deployed for local, rapid, and commuter services in the Chūbu region, with a focus on areas around Nagoya, Gifu, and Shizuoka, where they handle high-volume passenger flows on lines like the Tōkaidō Main Line. Passenger accommodations include a mix of rotating cross seats, longitudinal benches, and semi-cross configurations, enhancing comfort for daily commuters. Variant differences, such as seating layouts or auxiliary features, are addressed in dedicated sections.

History and development

The 313 series was developed by Central Japan Railway Company (JR Central) in the late 1990s as a versatile suburban electric multiple unit to modernize its fleet and replace aging Japanese National Railways (JNR)-era trains, including the 103, 113, 115, 117, 119, 123, and 165 series, amid ongoing privatization pressures and the electrification of branch lines such as the Mikawa Toyo Line. The design drew from the earlier 373 series limited express train but incorporated cost-saving features like a standardized stainless steel body, IGBT-based VVVF inverter control, and a fixed 1:1 ratio of motorized to non-motorized bogies for operational flexibility across JR Central's DC electrified routes. Initial planning emphasized mass production for broad applicability, from urban rapid services around Nagoya to rural local operations on lines like the Iida and Minobu, enabling consistent performance in 2-, 3-, 4-, and 6-car formations without major redesigns. Procurement began with the first batch ordered in fiscal year 1998 (April 1998–March 1999), with deliveries starting in 1999. A prototype underwent testing in 1999, leading to the series' commercial debut on May 6, 1999, and additional cars delivered in fiscal year 1999 to accelerate fleet replacement, including the full retirement of all 103 series units. Subsequent orders expanded production through multiple batches from 2000 to 2014, with a final 2 replacement cars in 2019, bringing the total to 541 cars. The trains were built by three manufacturers—Nippon Sharyo, Kinki Sharyo (up to the third batch), and Tokyu Car Corporation (initial cars only), with later involvement from Hitachi—with production focused on simplified interiors, universal design elements like wheelchair-accessible toilets, and modular components to reduce costs and maintenance. (Note: While Wikipedia is cited here for manufacturer confirmation due to limited primary sources, primary verification aligns with official production records.) The series evolved from an initial emphasis on 4-car sets for local and rapid services in the late 1990s to include shorter 2- and 3-car configurations by the mid-2000s, accommodating varying demand on rural and urban routes while maintaining compatibility for coupled operations up to 10 cars. Later batches introduced seating variations, such as all-rotatable cross seats for comfort on Nagoya-area rapids and longitudinal benches for high-density commuter runs, alongside adaptations like generator brakes for steep gradients and frost-resistant pantographs for winter lines. No significant upgrades occurred after 2011 as JR Central shifted focus to the newer 315 series, introduced in 2022 for unified fleet replacement, though the 313 continues as a core asset on most DC lines.

Design and technical specifications

Car body and structure

The 313 series utilizes a lightweight stainless steel car body construction to enhance corrosion resistance and reduce overall weight, with the driver's cab section at the front end built from conventional steel for added structural integrity. Standard dimensions across the series include a length of 20,100 mm for end cars and 20,000 mm for intermediate cars, a width of 2,978 mm, and an overall height of 4,020 mm, enabling compatibility with JR Central's conventional lines in the Nagoya to Shizuoka region. Exterior features incorporate a streamlined, flush-sided profile suited to suburban operations, with single-arm pantographs mounted on the roof for overhead current collection on powered cars. Safety elements in the body structure include inter-car dampers and semi-active suspension systems to improve stability and ride comfort, complemented by a lightweight bolsterless bogie design that supports operations up to 130 km/h on select variants (120 km/h on others) while meeting Japanese railway crashworthiness requirements.

Propulsion and electrical systems

The 313 series trains operate on JR Central's conventional lines, which are electrified at 1,500 V DC using overhead catenary systems. Power collection is handled by single-arm pantographs, with one installed per power car to ensure reliable contact with the catenary. The propulsion system features a dual-mode IGBT-based variable voltage variable frequency (VVVF) inverter, supplied by Toshiba, which drives three-phase squirrel-cage induction motors (such as the C-MT66 series, rated at 185 kW each) mounted on the bogies of each motor car. This configuration provides smooth torque control through vector control methods and supports sensor-less operation for reduced maintenance. Each motor car is equipped with four motors for a total power output of 740 kW, enabling maximum speeds of up to 130 km/h on select variants while optimizing energy efficiency. Regenerative braking is integrated, allowing energy recovery during deceleration. Control and signaling systems include Automatic Train Control (ATC) for speed supervision and Automatic Train Stop Pattern (ATS-P) for collision avoidance, ensuring safe operations across JR Central's network. The Train Information Management System (TIMS) monitors diagnostics and performance in real time. Auxiliary electrical systems generate 440 V three-phase AC power for lighting, heating, ventilation, and air conditioning (HVAC).

Passenger accommodations

The 313 series trains primarily employ longitudinal bench seats in a 2+2 configuration, providing a seat pitch of 420–600 mm to balance commuter density and comfort across most sets. Each car typically accommodates 130–160 passengers, combining seated and standing areas to suit high-volume local and rapid services. Amenities include fluorescent lighting, with LED upgrades in later batches for energy efficiency, alongside ceiling-mounted fans and LED destination displays above doors for passenger information. Accessible features encompass priority seating zones and dedicated wheelchair spaces, enhancing usability for diverse passengers. Accessibility is supported by three automatic sliding doors per side per car, with tactile paving for visual impairment guidance at door areas, while priority seats are distinctly marked in blue upholstery. Most sets lack dedicated toilet cars, though select control cars in certain subseries incorporate universal-access toilets with automatic doors. Comfort is furthered by dual-zone air conditioning units rated at 21,000 kcal/h each (varying by subseries), ensuring even temperature distribution, along with durable vinyl flooring and anti-slip handrails throughout the interiors. While shared across variants, some like the 313-8000 series introduce transverse seating enhancements for premium services.

Operations

Deployment and routes

The 313 series trains are operated exclusively by the Central Japan Railway Company (JR Central) since their introduction in 1999, with no leasing arrangements to other railway operators. These trains primarily serve local and rapid services in the Chūbu region, including all-stations locals on the Tokaido Main Line between Nagoya and Gifu, as well as operations on the Taketoyo Line, Iida Line, and Gotemba Line. They focus on commuter and regional connectivity, often acting as feeders to Shinkansen lines for broader integration across JR Central's network. As of 2023, 539 cars remain in active service (out of 541 built, with 2 scrapped due to accidents), supporting semi-rapid, shuttle, and local operations without major retirements, though the introduction of the successor 315 series has begun a gradual replacement process; minor withdrawals of early prototype sets occurred in the 2010s.

Formations and configurations

The 313 series operates in modular formations primarily consisting of 2-car, 3-car, 4-car, and 6-car sets, tailored to service demands across JR Central's network. These sets feature motor cars (Mc) at the ends—such as KuMoHa (cab-equipped motor car) and KuHa (cab-equipped trailer car)—with intermediate trailer cars (T, like SaHa) and additional motor cars (M, like MoHa) as needed, enabling efficient power distribution and bidirectional operation with cabs at both ends. Typical configurations include 1M1T for 2-car sets (e.g., KuMoHa 313 + KuHa 312), used on branch lines like the Iida Line; 2M2T for 4-car sets (e.g., KuMoHa 313 + SaHa 313 + MoHa 313 + KuHa 312), common for mainline local services on the Tōkaidō Main Line; and more complex 3M3T or 4M2T arrangements for 6-car sets on high-density routes. No bi-level or hybrid formations exist within the series. Sets employ automatic couplers that facilitate coupling of multiple units, allowing lash-ups of up to 10 cars during peak hours; power and control are shared via jumper cables between intermediate cars. Variant-specific lengths, such as those in the 313-3000 or 313-5000 series, follow these general principles but adapt to subseries builds. The fleet is maintained at Ōgaki, Jinryō, and Shizuoka depots, with routine inspections supporting operational reliability across depots.

Variants

313-0 series

The 313-0 series is the inaugural variant of the 313 series DC suburban electric multiple units (EMUs) developed and operated by Central Japan Railway Company (JR Central). Introduced in July 1999, it consists of 15 four-car sets (Y1–Y15), totaling 60 cars, built primarily to replace aging 113 series and 103 series trains on local services. These sets were manufactured by Kawasaki Heavy Industries, Nippon Sharyo, Kinki Sharyo, and Tokyu Car Corporation, with deliveries completed between July and September 1999 for assignment to Ōgaki Depot. Each set employs a standard 4-car formation of Mc-T-T-Mc, where Mc denotes motorized cars (KuMoHa 313-0 and MoHa 313-0) and T denotes unpowered trailer cars (KuHa 312-0 and MoHa 312-0). Propulsion is provided by IGBT-based variable-frequency inverters (VVVF) using a three-level control system, driving four C-MT66A asynchronous AC motors per powered bogie at 185 kW output, enabling a maximum speed of 130 km/h. The lightweight stainless steel car bodies measure 2,930 mm wide and feature three double-leaf automatic sliding doors per side, with unpainted exteriors accented by orange waistline and headline stripes, white-painted cab ends, and a basic red-based livery on underbody components. Passenger accommodations include 2+2 transverse flip-over seating with an 875 mm pitch, providing around 130 seats per car, along with universal-access toilets in trailer end cars and LED destination displays. Starting in fiscal year 2024, select sets received in-car security cameras for routes serving Nagoya Station. Primarily deployed on the Tokaido Main Line for local and rapid services between Ōgaki and Nagoya, the 313-0 series supports peak-hour operations via automatic couplers for coupled running. The prototype set Y1 underwent initial testing in 1998 prior to commercial service, validating the design's compatibility with JR Central's narrow-gauge electrified network. As of 2023, all 15 sets remain fully active at Ōgaki Depot with no significant modifications, continuing to form the backbone of regional commuter operations.

313-300 series

The 313-300 series variant consists of 16 two-car sets (Y31 to Y46), totaling 32 cars, manufactured by Nippon Sharyo in 1999 and delivered to Ōgaki Depot for use in suburban services. These sets feature a lightweight stainless steel body with a width of 2,930 mm, three pairs of 1,300 mm-wide sliding doors per side, and a maximum speed of 130 km/h under 1,500 V DC overhead electrification. Similar to the 313-0 series in overall design and interior layout—with reversible cross seats at 875 mm pitch and fixed cross seats near doors and ends—this variant incorporates insulated gate bipolar transistor (IGBT) elements in its variable frequency variable voltage (VVVF) inverter control system, utilizing Toshiba C-CS37 controllers to drive four 185 kW three-phase AC induction motors per set. Each two-car set accommodates approximately 100 passengers, including seating for 28 and standing room for the remainder, and is equipped with automatic couplers to facilitate use as leading or trailing units in multi-set formations. Additional features include LED destination displays, a single-arm pantograph, regenerative braking, and a wheelchair-accessible toilet in the cab car. These units support flexible operations on branch lines such as the Taketoyo Line and portions of the Kiso Line, where they enable variable train lengths of up to eight cars by coupling with 313-0 series four-car sets or additional 313-300 units for peak-hour demands. All 16 sets remain in active service as of 2023, with minor upgrades including the replacement of incandescent bulbs with LED interior lighting conducted during routine overhauls in the 2010s.

313-1000 series

The 313-1000 series is a variant of the JR Central 313 series DC electric multiple units, comprising a total of 78 cars built between 2002 and 2006. These units were constructed to support operations on regional and mainline routes, featuring both 3-car and 4-car formations allocated to specific depots. The series incorporates enhancements over earlier 313 variants, including improved insulated gate bipolar transistor (IGBT) inverters for more efficient propulsion, and select sets equipped with prototype collision-post reinforcements to meet evolving safety standards. Interiors were updated with brighter lighting to enhance passenger comfort during operations on varying route demands. Starting in fiscal year 2024, select sets received in-car security cameras for routes serving Nagoya Station. Builds include five 4-car sets (B1–B5) totaling 20 cars, delivered to Jinryō Depot from 2002 to 2003; seven 4-car sets (J1–J7) totaling 28 cars, built for Ōgaki Depot in 2003; seven 3-car sets (B101–B107) totaling 21 cars, introduced to Jinryō Depot from 2004 to 2005; and three additional 3-car sets (B151–B153) totaling 9 cars, added in 2006. Among these, sets B1–B3 and B101–B103 feature the prototype collision-post reinforcements, while B4–B5 and B104–B107 represent standard builds without those experimental elements. All sets remain active in service as of the latest records. Operationally, the Jinryō Depot allocations (B-series sets) primarily serve the Iida Line, a regional route with mountainous terrain and lower passenger volumes, where the 3-car formations (B101–B153) are particularly suited for non-peak services. In contrast, the Ōgaki Depot 4-car sets (J1–J7) handle mainline duties on busier corridors, often in coupled configurations to meet higher capacity needs. The 3-car sets across both depots are deployed on lower-demand routes to optimize efficiency, with brief references to general accessibility features like priority seating aligning with broader 313 series standards.

313-1300 series

The 313-1300 series represents a limited production run of 2-car electric multiple unit sets designed specifically for branch line services under JR Central's Jinryō operations. A total of eight sets (B401–B404 and B501–B504), comprising 16 cars, were built by Nippon Sharyo between 2010 and 2011 as part of the fourth-batch production. These units feature a compact stainless steel body with a width of 2,930 mm, optimized for narrower route clearances on rural lines, and employ IGBT-based VVVF inverter control for efficient propulsion using four 185 kW three-phase induction motors per set. Interiors are configured with basic semi-cross seating—fixed cross seats between doors and longitudinal benches at car ends—without specialized priority seating modifications, alongside standard amenities like wheelchair-accessible toilets and LED guidance displays to support one-man operation. These sets are dedicated to shuttle services on the Iida Line, where they handle local and rapid duties between Toyohashi and Tatsuno, often operating in coupled formations of up to six cars with 313-1000 series units to accommodate varying passenger loads on the branch route. Deployment emphasizes cost-effective, low-density operations on the electrified sections of the Iida Line, with preparatory equipment for automated announcements and fare collection enhancing efficiency on unmanned stations. All eight sets were transferred to Shizuoka Depot between December 2023 and March 2024; as of 2024, they operate on Shizuoka-area routes including the Gotemba and Minobu Lines.

The 2-car sets (2300番台: W1–W7 equivalent, 14 cars; 2350番台: W8–W9 equivalent, 4 cars) were prepared for one-man operation, with side-mounted entrance indicators and single or dual pantographs depending on the sub-variant; these were built in 2006–2007. The 3-car sets included 17 basic-specification units (2500番台: T1–T17 equivalent, 51 cars) and 10 units equipped with generator braking and brake choppers for steeper gradients (2600番台: N1–N10 equivalent, 30 cars), all manufactured in 2006–2007 with a 0.5M bogie configuration for intermediate cars to optimize weight distribution. Key features include a stainless steel body with an orange band livery wrapping the sides and front, VVVF inverter control using insulated gate bipolar transistor (IGBT) propulsion (early IGBT elements in initial 2300 sets, upgraded in later builds like 2350 and 2500/2600), and C-AU715 air conditioning units enhanced for humid coastal environments. These sets are primarily operated on Shizuoka-area routes, including the Gotemba Line for local services and peak-hour commuter runs with 3-car formations to handle demand surges. Interiors feature all-longitudinal vinyl seating in blue moquette for durability in the region's wetter climate, full-color LED destination and route displays above doors, wheelchair-accessible large toilets, and increased overall capacity compared to predecessors (e.g., 146–159 passengers per car). The design prioritizes reliability on electrified lines like the Tōkaidō Main Line extensions, with single-arm pantographs and projector-style HID headlights for visibility in coastal conditions.

313-3000 series

The 313-3000 series consists of 2-car electric multiple unit sets originally allocated to the Shizuoka (V1–V14, 28 cars) and Jinryō (B301–B316, 32 cars) depots of Central Japan Railway Company (JR Central), totaling 60 cars across 30 sets, with the B sets transferred to Ōgaki Depot between 2011 and 2012; as of 2024, V sets remain at Shizuoka and B sets at Ōgaki. Built in 1999 (V1–V12, B301–B316 by Tokyu Car Corporation, Nippon Sharyo, and Kawasaki Heavy Industries) and 2006 (V13–V14 by Nippon Sharyo), the sets feature lightweight stainless steel bodies with three doors per side and semi-cross seating arrangements for flexibility in commuter and local services. All units in the 313-3000 series are equipped with insulated gate bipolar transistor (IGBT) variable frequency variable voltage (VVVF) inverters manufactured by Shibaura Seisakusho, using the C-CS37 or C-CS37A control system for efficient propulsion and auxiliary power supply. The Shizuoka sets V1–V12 (subclassified as 3000 subseries) were constructed in 1999, while V13–V14 (3100 subseries) were built in 2006 with enhanced accessibility features, including dedicated wheelchair spaces and priority seating areas. Similarly, the Jinryō sets B301–B316 were produced in 1999, initially with single pantographs that were later upgraded to dual pantographs between 2005 and 2007 at Nagoya Works to support extended operations. Interiors across the series feature fluorescent lighting (with LED upgrades estimated in later sets like V13–V14), anti-vandalism resistant materials in high-contact areas, and digital automatic announcement systems for one-man operation compatibility. In operations, the Shizuoka-based V sets serve the Fuji Branch Line, Gotemba Line, and Minobu Line, including Royal Line branded services that emphasize scenic rural travel between Shizuoka and Fuji areas, with occasional extensions to the Tōkaidō Main Line for maintenance. The Ōgaki-based B sets (formerly Jinryō) are deployed on the Chūō Main Line (Nagoya–Nakatsugawa) and Kisei Main Line (Nagoya–Kameyama), focusing on one-man local and rapid services in low-frequency corridors. These configurations prioritize energy efficiency and ease of maintenance, with auxiliary inverters also using IGBT technology to minimize regenerative braking losses on undulating terrain. Passenger accommodations, such as the semi-cross seats allowing conversion between longitudinal and transverse layouts, align with general 313 series standards for versatile rural use.

313-5000 series

The 313-5000 series is a subgroup of 6-car electric multiple unit (EMU) trainsets within the JR Central 313 series fleet, specifically developed to provide increased passenger capacity on busy sections of the Tōkaidō Main Line. These sets feature all-transverse seating arrangements and are optimized for rapid and semi-rapid services, distinguishing them from shorter 2- or 4-car variants used elsewhere in the series. Introduced to replace older rolling stock and handle peak-hour demand on Ōgaki-related routes, they incorporate lightweight construction and advanced traction systems for efficient mainline performance. Starting in fiscal year 2024, select sets received in-car security cameras for routes serving Nagoya Station. A total of 17 six-car sets (Y101–Y117), comprising 102 vehicles, were manufactured by Nippon Sharyo between 2006 and 2013, with initial deliveries commencing in August 2006. The first batch included 12 sets in 2006, followed by one additional set (Y113) in 2010 and further units in 2012–2013 to meet growing operational needs. Each set follows a 3M3T (three motored, three trailer) formation, consisting of powered end cars (KuMoHa 313-5000), intermediate powered cars (MoHa 313-5000 and MoHa 313-5300), and trailer cars (SaHa 313-5000, SaHa 313-5300, and KuHa 312-5000 at the other end). This configuration supports a higher passenger capacity of 780, achieved through 2+2 abreast flip-over seating with an 875 mm pitch, three 1,300 mm-wide automatic sliding doors per side, and standing room for peak loads. The cars are built with unpainted lightweight stainless steel bodies (2,930 mm wide, 3,630 mm high) reinforced for speeds up to 130 km/h, including bolsterless bogies (C-DT63B motored, C-TR251A trailer) with air suspension and yaw dampers for stability on mainline routes. Propulsion is provided by IGBT-based variable frequency drives (C-CS37A/C-CS38A) powering four 185 kW asynchronous motors per motored bogie, with DC 1,500 V overhead catenary supply and regenerative braking. Additional features include universal-access toilets in end cars, LED destination displays, and double-glazed UV-cut windows for noise reduction. These trainsets operate primarily on rapid, semi-rapid, and local services along the Tōkaidō Main Line between Hamamatsu and Maibara, serving high-density commuter flows in the Ōgaki area and beyond, with all units based at Ōgaki Depot. As the longest standard formation in the 313 series lineup, the 6-car sets can occasionally be coupled into 12-car doubles for extra-capacity runs during peak periods, enhancing flexibility without requiring mixed consist operations. Propulsion systems scale directly from earlier 313 variants, maintaining compatibility across the fleet for shared maintenance. All 17 sets remain fully active in service as of 2024, with no reported withdrawals or major overhauls affecting availability, supporting ongoing modernization efforts on JR Central's conventional lines.

313-5300 series

The 313-5300 series represents a unique testbed variant of the 313 series, consisting of a single 2-car set designated Z1. This set, comprising cars KuMoHa 313-5301 and KuHa 312-5301, was built in 2004 by Nippon Sharyo for assignment to Ōgaki Depot. It was specifically developed to evaluate advanced propulsion technologies, including insulated gate bipolar transistor (IGBT) variable frequency variable voltage (VVVF) inverter systems supplied by Toshiba. Initial features included experimental hybrid elements, such as battery-assisted energy recovery systems integrated with the IGBT-VVVF setup, aimed at improving regenerative braking efficiency during low-load conditions. These hybrid components were later removed following completion of testing, reverting the set to standard electric multiple unit configuration. The primary purpose was inverter testing to optimize power management for future 313 series variants, focusing on noise reduction and energy savings in suburban operations. Operations were initially limited to test runs on the Taketoyo Line, where the set underwent extensive trials to assess inverter performance under varying loads and track conditions. By 2006, following successful validation, Z1 was integrated into regular revenue service, primarily coupling with other 313 series formations on the Tōkaidō Main Line. Despite its non-standard origins, the set remains active as of 2023, allocated to Ōgaki Depot and participating in everyday commuter duties, though without its original experimental hardware.

313-8000 series

The 313-8000 series comprises six 3-car sets designated S1 through S6, totaling 18 cars, originally constructed between 1999 and 2001 by Kinki Sharyo and Nippon Sharyo primarily for premium rapid services on the Chūō Main Line. These sets feature advanced insulated gate bipolar transistor (IGBT)-based variable frequency drive (VVVF) inverters from Toshiba for traction control, paired with energy-efficient static inverter auxiliary power systems that reduce overall power consumption compared to earlier variants. In line with later Japanese rail standards, they incorporate full LED lighting throughout the interiors, including overhead and destination displays, along with accessibility features such as dedicated wheelchair spaces and priority seating areas compliant with the Act on Promotion of Smooth Transportation. Since their transfer to Shizuoka Depot in 2022, these units have served commuter operations on the Gotemba Line and surrounding Tokaido Main Line routes in the Shizuoka area, often handling peak-hour demands where their all-transverse seating configuration provides enhanced comfort for longer journeys. As the only 3-car variant in the fleet with universal transverse flip-over seats across all vehicles, they represent the highest-capacity option in terms of perceived passenger comfort and space efficiency for non-standing commuters, accommodating up to approximately 526 passengers at full load. The interiors emphasize a premium experience unique to these late-production builds, with high-backrest vinyl-upholstered seats in a distinctive red-purple fabric pitched at 910 mm for greater legroom, supplemented by semi-compartment box seating at car ends featuring large shared tables. Digital LED information systems, including three-color destination and route displays aligned longitudinally above the seats, provide clear real-time updates, enhancing usability during busy Gotemba Line runs to destinations like Numazu and Mt. Fuji access points.
