The British Rail Class 768 is a class of bi-mode multiple unit being converted from Class 319 passenger trains by Brush Traction and Wabtec to carry parcels.
History
[edit]In December 2018, Rail Operations Group (ROG) ordered two Class 769s that were in the process of being developed by Brush Traction from redundant Class 319s, owned by rolling stock company (ROSCO) Porterbrook.[2] However unlike the Class 769s that remained as passenger trains, ROG's Orion High Speed Trains subsidiary intends to operate them as parcel carriers from London Liverpool Street to London Gateway.[3][4]
In February 2020, a further three were ordered to allow services to be introduced the Midlands to Scotland via the West Coast Main Line.[5] A further five has since been ordered. Originally to be classified as Class 769/5s, they were reclassified as the Class 768 before the first unit was completed.[6]
The first units received their traction conversions at Brush Traction, Loughborough, while the latter examples will be completed by Wabtec at Doncaster Works. They then move to Eastleigh Works where Arlington Fleet Services fit out the interiors and fit roller doors to carry pallets, bulk items and parcel cages.[6]
The units will operate in fixed formations of four (capable of running in multiples) at up to 100 mph. Unlike conventional rail freight, this provides direct access to city centres, with onward distribution from stations to be by van or bicycle courier. A demonstration from London Euston took place on 7 July 2021.[2][7]

British Rail Class 768
View on Grokipediafrom Grokipedia
The British Rail Class 768 is a class of bi-mode multiple units converted from redundant Class 319 electric passenger trains for parcels and small-volume freight operations. These four-car units, leased from Porterbrook and modified by Wabtec Rail (formerly Brush Traction) at their Doncaster facility, combine electric traction under 25 kV AC overhead or 750 V DC third-rail systems with diesel engines for non-electrified routes, achieving a maximum speed of 100 mph (160 km/h). Intended to be operated by Orion—a logistics subsidiary of the Rail Operations Group—the Class 768 was designed to enable efficient, low-emission transport of pallets, roll cages, and custom containers equivalent to the load of an articulated lorry per car, with an eight-car formation capable of replacing up to 24 diesel vans on congested roads.[1][2]
The project originated in December 2018 when Rail Operations Group ordered two prototype bi-mode conversions from Brush Traction, initially designated as Class 769/5 but reclassified as Class 768 to reflect their dedicated freight role and comply with vehicle numbering requirements. The first unit, 768001, was publicly unveiled on 7 July 2021 at London Euston station, where it was demonstrated to potential customers ahead of planned revenue service. This marked a pioneering effort to repurpose withdrawn passenger stock for sustainable freight, targeting urban delivery challenges by allowing rail haulage to city centers followed by last-mile distribution via electric bikes or vans.[1][2]
Although revenue operations were planned to commence in late 2021 with Anglo-Scottish services via the West Coast Main Line, initially linking the Midlands to central Scotland (such as Wembley to Shieldmuir), and with ambitions for expansion to a broader network from Plymouth to Aberdeen, the units did not enter service. Plans for additional conversions were put on hold in 2022 following the closure of Wabtec's Loughborough facility, and as of 2025, the two prototypes remain stored at Crewe and out of use.[3][2][4][5]
Background
Origins in Class 319
The British Rail Class 319 electric multiple units (EMUs) originated as dual-voltage passenger trains constructed by British Rail Engineering Limited (BREL) at its York and Holgate carriage works. A total of 86 four-car units were built across two main subclasses: the Class 319/0 from 1987 to 1988 and the Class 319/4 from 1990. These units were designed specifically for suburban and regional passenger services on electrified lines, with the primary focus on the Thameslink route connecting Bedford to Brighton via central London.[6][7][6] Key technical features inherited by later conversions include a four-car formation, a maximum operating speed of 100 mph (160 km/h), a body height of 3.58 m, and a width of 2.82 m, with individual car lengths ranging from 19.83 m to 19.92 m. Originally equipped for dual-voltage operation, the Class 319 units drew power from 25 kV 50 Hz AC overhead lines or 750 V DC third rail collection, enabling seamless transitions across London's electrified network. This configuration supported efficient suburban operations while adhering to the BR Mark 3 bodyshell standards for reliability and passenger capacity.[8][6][9] Initially operated by Network SouthEast (NSE) from their entry into service in 1989, the Class 319 fleet became synonymous with Thameslink services, providing cross-London connectivity. Following rail privatisation in the 1990s, the units served various train operating companies (TOCs), including Thameslink, Southern, and First Capital Connect, before being cascaded northward to operators such as Northern Rail (later Northern Trains) and West Midlands Trains in the 2010s. Withdrawals commenced in 2017, driven by fleet cascading to accommodate new electric units like the Class 700 on Thameslink and ongoing electrification projects that rendered the aging Class 319s surplus to passenger requirements.[10][6][11]Rationale for parcel conversion
The surge in e-commerce during the late 2010s amplified the demand for efficient, sustainable urban parcel delivery, positioning rail as a low-emission alternative to diesel vans for last-mile access into congested city centers. This market shift highlighted the potential for repurposing existing rail infrastructure to handle small-volume freight, reducing road congestion and emissions in urban areas. Surplus Class 319 electric multiple units became available after their withdrawal from passenger service, notably by Thameslink in 2017 and subsequent disposals by Northern Rail from 2018 onward, driven by fleet modernization initiatives and the units' limitations on non-DC electrified routes.[12][13] In December 2018, Rail Operations Group ordered two prototype bi-mode conversions from Brush Traction, initially designated as Class 769 units leased from Porterbrook.[1] In February 2019, Rail Operations Group (ROG) launched its Orion Logistics subsidiary to trial parcel and light freight services, targeting a UK-wide network from logistics hubs to major urban terminals. Initially integrated into the broader Class 769 bi-mode passenger conversion program, the parcel-focused units were reclassified as Class 768 in 2020 to distinguish their dedicated freight configuration. This approach offered economic advantages through cost-effective retrofitting of proven assets rather than procuring new vehicles, while utilizing Porterbrook's existing leasing framework to minimize upfront capital. Environmentally, the initiative supported UK rail freight decarbonization objectives by facilitating a modal shift from road haulage, with each eight-car train capable of displacing the equivalent of 24 diesel vans and lowering overall logistics emissions. While ambitious plans envisioned fleet expansion, as of November 2025 only the two prototype units have entered limited revenue service.[1]Design and specifications
Bi-mode power system
The British Rail Class 768 units retain the dual-voltage electric power collection system of their Class 319 origins, capable of operating under 25 kV 50 Hz AC overhead lines or 750 V DC third rail for propulsion in electric mode.[14] For diesel operation on non-electrified sections, each four-car unit is equipped with two MAN D2876 turbocharged diesel engines, one fitted under the floor of each driving trailer, delivering a combined output of 780 kW (1,046 hp).[15][16] These engines drive alternators that feed electrical power into the train's DC bus, powering the existing traction and auxiliary systems without major alterations to the underframe.[17] The original GEC Traction (now ABB) G315BZ DC traction motors, mounted on the bogie axles, are retained and utilized in both modes, with the diesel alternators providing the necessary DC supply during non-electric running.[17] Conversion to diesel-electric multiple unit (DEMU) configuration includes an updated electronic control system for engine management, enabling automatic and seamless transitions between electric and diesel modes while maintaining consistent performance.[17][18] The bi-mode setup achieves a maximum speed of 100 mph (161 km/h) in either mode, supporting efficient freight operations on mixed electrification networks such as the West Coast Main Line by minimizing diesel use where overhead or third-rail power is available.[14][2]Adaptations for freight use
The British Rail Class 768 units underwent significant interior refits to convert the former passenger accommodations of the Class 319 into open cargo holds optimized for parcel and pallet transport. All seating, which originally accommodated 202–234 passengers per four-car unit, along with partitions, luggage racks, and toilets, was removed to create flexible, unobstructed spaces. Modular racking and shelving systems were installed to secure pallets, rollcages, and parcels of varying sizes, allowing reconfiguration based on customer requirements such as high-volume e-commerce goods or time-sensitive deliveries. Equipment like the On-Train Monitoring Recorder was relocated to the roof to preserve internal volume, while an Ethernet backbone was added for real-time goods tracking and load optimization.[19][20] Loading mechanisms were enhanced by retaining and reinforcing the original side-loading sliding doors, enabling efficient access at passenger stations or dedicated terminals. Forklift-compatible flooring was incorporated, complemented by multiple tie-down points and restraint systems to ensure secure cargo placement during high-speed operations up to 100 mph. This setup supports pallets, rollcages, and custom containers, with an online booking system facilitating seamless integration into logistics chains. Each vehicle provides a payload capacity of 12.5 tonnes, yielding up to 50 tonnes per four-car unit when fully loaded with mixed freight (as of 2021).[19][1][4] Safety features were upgraded to address freight-specific risks, including enhanced fire suppression systems compliant with cargo transport standards and improved ventilation to maintain conditions for perishable items like pharmaceuticals or fresh produce. The original aluminum body shell was preserved for its lightweight durability, with targeted reinforcements to the underframes to withstand the increased static and dynamic loads from cargo. Driving cabs remained intact at each end, augmented with secure storage compartments, while crew facilities were streamlined to essentials like basic controls and monitoring, reflecting the reduced staffing needs of freight services.[19] The existing BREL BT13 bogies are retained, ensuring compatibility with the bi-mode power system without major redesign. These adaptations collectively enable the Class 768 to operate as a versatile parcel carrier on both electrified and non-electrified routes, prioritizing speed and urban accessibility over traditional bulk freight (design as of 2021 prototype conversions; no major changes reported by 2025).[16]Construction and conversion
Original construction
The British Rail Class 319 electric multiple units, serving as the donor vehicles for the later Class 768 parcel carriers, were constructed in two main batches between 1987 and 1990 at British Rail Engineering Limited's (BREL) facilities in York. Driving cars were assembled at the Holgate Road carriage works, while intermediate cars were produced at the adjacent York Carriage Works, enabling efficient modular integration into four-vehicle formations.[21][7] The assembly process employed a modular approach with double-skin welded aluminum bodies, based on the established BR Mark 3 coach profile, to ensure lightweight construction and aerodynamic efficiency suitable for cross-London services. Units were built sequentially to form complete electric multiple unit (EMU) sets, incorporating underframe-mounted equipment for dual-voltage operation on both 750 V DC third rail and 25 kV 50 Hz AC overhead lines. Key components included 4 × GEC G315BZ traction motors providing a total of 990 kW (1,330 hp), Stone Faiveley AMBR pantographs for overhead collection, and BREL-designed bogies optimized for stability at up to 100 mph.[7] Quality control adhered to British Rail's engineering standards of the era, emphasizing compatibility with third-rail electrification systems and basic crashworthiness features prior to later 1990s enhancements, such as improved end structures. Initial testing focused on dynamic braking performance, conducted on the Great Northern lines north of London, to validate regenerative and rheostatic systems under operational loads. Certification confirmed the units' capability for 100 mph maximum speed, with all sets undergoing load trials and acceptance runs before entry into service.[7] Upon completion, the units were delivered directly to Network SouthEast for deployment on Thameslink routes, with the first entering passenger service in 1990. The original batch comprised Class 319/0 units, while a subsequent variant, Class 319/3, featured modified longer trailer cars to accommodate additional seating capacity, and both subclasses provided the donor fleet for later conversions.[21][7]Conversion modifications
The conversion of Class 319 passenger multiple units to the bi-mode Class 768 for parcel freight was derived from the earlier Class 769 passenger project, with the first two units repurposed following the abortion of that initiative for non-passenger operations.[19] The project initially planned for 10 four-car units, leased from Porterbrook and developed by Orion, a subsidiary of Rail Operations Group (UK) Ltd.[1] Work began in late 2018, with the first unit, 768001 (formerly designated 769501), completing conversion by July 2021, and the second unit, 768002, by late 2021; further conversions were suspended following the closure of Brush Traction's facility, resulting in only two units being completed. As of 2023, no additional units have been reported.[19][4] Primary contractors included Brush Traction at Loughborough for powertrain integration, particularly the installation of MAN D2876 diesel engines under the driving vehicles to enable bi-mode operation alongside the existing 25 kV AC electric capability.[19][16] Following Brush's closure at the end of 2021, Wabtec took over mechanical work, though no further units were processed at Doncaster Works. Interior fit-out for the units occurred at Eastleigh Works and by Arlington Fleet Services, involving the removal of passenger fittings such as seats, toilets, and luggage racks, along with relocation of the on-train monitoring recorder (OTMR) to the roof and the addition of an Ethernet backbone for cargo tracking.[19] Key modification steps focused on adapting the units for freight, including diesel engine installation for diesel-electric mode, electrical rewiring to support integrated bi-mode control systems, and structural reinforcements to handle cargo loads equivalent to articulated lorries per car.[1] These changes facilitated configurable formations of 4, 8, or 12 cars, with cargo racking for pallets, roll cages, and custom containers, while maintaining a maximum speed of 100 mph.[1] The units were reclassified from Class 769/5 to Class 768 in early 2020 to reflect their dedication to freight service, prior to the first completion.[19] Testing phases commenced with static load tests at Hams Hall in August 2021 to verify freight certification, followed by bi-mode operational trials on routes including the West Coast Main Line (WCML), with route acceptance testing conducted ahead of revenue service.[19] Main line proving runs, such as those between Hams Hall and Mossend, confirmed the units' performance in both electric and diesel modes.[19]Operational history
Entry into service
The first British Rail Class 768 unit was unveiled on 7 July 2021 at London Euston station, where it was demonstrated to potential customers by Orion Logistics to showcase its capabilities for parcel freight transport.[1] This event marked the public debut of the bi-mode conversion from former Class 319 passenger stock, highlighting features such as pallet and rollcage accommodation designed for high-speed logistics.[1] The initial operator was the Rail Operations Group (ROG) through its subsidiary Orion Logistics, with the units leased from Porterbrook.[1] Entry into revenue service was planned for late 2021, beginning with trials managed by ROG on the Anglia route to test integration into the freight network.[19] Certification for bi-mode freight operations was secured through reclassification by the Office of Rail and Road (ORR), which required the shift from Class 319/769 designations to Class 768 to accommodate non-passenger use.[19] Pre-operational challenges included the closure of Brush Traction and the transfer of conversion work to Wabtec Rail's Doncaster facility.[19] A key milestone planned was the first revenue run in December 2021, operating from London Liverpool Street to London Gateway as part of secured path allocations for parcel services, but this did not occur.[19] Expansion plans were announced in 2021–2022, targeting a fleet of 10 Class 768 bi-mode units alongside nine Class 326 electric multiple units to support growing demand, but only two units were converted, and further work did not proceed.[19][1][22]Routes and services
The Class 768 units were planned to operate on the route from London Liverpool Street to DP World London Gateway Port, with bi-weekly services dedicated to parcel distribution for e-commerce and logistics clients.[22] Initial services were intended to include Anglo-Scottish routes from the Midlands to central Scotland via the West Coast Main Line, utilizing the electric mode on electrified sections to enhance fuel efficiency and reduce emissions.[2][1] Under operator Orion Logistics, services were planned to begin as ad-hoc charters in late 2021, with intentions to scale to daily frequencies by 2023–2025 to meet growing demand for rail-based parcel transport, but the project paused without entering revenue service.[1] These operations were designed to integrate with ground-based logistics through last-mile handoffs at terminals, employing vans and bicycles for urban delivery, in partnership with e-commerce firms to facilitate rapid distribution in city centers.[1] Future prospects included potential adoption by additional operators and extension to routes such as the East Coast Main Line by 2026, further supporting the UK's shift toward sustainable freight, though these remain unrealized.[22] As of 2025, the two units (768001 and 768002) are in storage at locations including Eastleigh Arlington and East Midlands Designer Outlet, with the Orion project paused and no revenue operations conducted.[22][23]Fleet details
Operational units
As of November 2025, no Class 768 units are in operational revenue service; both are in storage with Rail Operations Group (ROG) under its Orion Logistics division, having last operated in 2023. These units were converted for parcels transport and leased from Porterbrook.[1][22] These units are standardized without variants or names, featuring bi-mode capability for electric and diesel operation to support freight on electrified and non-electrified routes.[3] No withdrawals have occurred.[4] The first unit, 768001, was converted from former Class 319 passenger unit 319010 and entered service in January 2022, initially trialled on Anglo-Scottish routes hauling parcels from facilities like Shieldmuir Mail Terminal.[3] It carries ROG's Orion livery in blue and grey, with the interior adapted for roll-cage parcels loading.[1] It has been stored at Castle Donnington since November 2023.[24] Unit 768002, converted from ex-319009, followed into service later in 2022 and shares the same blue/grey Orion livery and parcels configuration.[4] It is stored at Coquelles. Both units were previously based at ROG depots, including facilities near Derby, for ongoing operations focused on high-speed logistics.[22]| Unit No. | Donor Unit | Entry into Service | Livery | Notes |
