The Great Western Railway (GWR) 2251 Class or Collett Goods Class was a class of 0-6-0 type steam tender locomotives designed for medium-powered freight. They were introduced in 1930 as a replacement for the earlier Dean Goods 0-6-0s and were built up to 1948.[2]

Overview

[edit]

In many ways, the 2251s were modernised Dean Goods, sharing the main dimensions, but having more modern features such as taper boilers and full cabs. Increases in both boiler pressure and heating surface gave a useful increase in power at the expense of weight that restricted permitted routes. Numbers 2211–2230, built in 1940 did not have side windows. Designed by Charles Collett for medium freight and passenger duties they had 5 ft 2 in (1.575 m) driving wheels. Carrying a maximum of 3,000 imperial gallons (14,000 L; 3,600 US gal) of water for a boiler operating at 200 psi (1.4 MPa), they developed 20,155 lbf (89.65 kN) of tractive effort. They could be found operating on most parts of the former GWR system. These were the first GWR 0-6-0 to use the standard number 10 boiler as later fitted to the 94xx, 15xx and various rebuilds of absorbed mainly Welsh locomotives.

No. 3217, delivered December 1947, was the last locomotive built by the GWR. Nos. 3218 and 3219 were delivered in January 1948, the first locomotives built at Swindon for British Railways.[4]

They were withdrawn between 1958 and 1965.

Preservation

[edit]
Preserved 3205 on the South Devon Railway.

One, 3205, has been preserved and is located on the South Devon Railway in Devon.[5] While the engine has spent most of its preserved life running on heritage railways including the Severn Valley Railway, West Somerset Railway & then the Dart Valley Railway (before renaming to the SDR). For a very brief one-off appearance the engine made a mainline appearance at the Rocket 150 celebrations in 1980. The engine arrived at the event and then later departed for home under its own power.

As of 2022 the engine is stored awaiting an overhaul following early withdrawal in 2017, the ticket having expired in 2020.

Models

[edit]

Bachmann Branchline manufactures models of the 2251 in OO gauge. Mainline (Palitoy) released the first ready-to-run OO model in 1978. The Bachmann model was released in 1996. It is based on the Mainline model with revised body tooling to complement a completely new chassis design that allows the boiler backhead to be modelled.

In British N gauge, the first model was the Langley whitemetal kit, designed to fit the Graham Farish 94xx/general purpose tank chassis. The next was the Peco ready-to-run model, introduced in 2007. This was a big step forward, and had DCC fitted as standard.[6] Production of these stopped around 2010. The next model of the class was made by Union Mills, released in 2017.

In 3mm/TT scale, BEC produced a whitemetal kit body for the Tri-ang LMS Fowler Class 3F chassis, though this is long discontinued.

GWR 2251 Class

View on Grokipedia
from Grokipedia
The GWR 2251 Class, also known as the Collett Goods Class, was a class of steam tender locomotives designed by for the Great Western Railway (GWR) to handle medium-powered freight duties, particularly on lines in . Built between 1930 and 1948 at , the class comprised 120 locomotives numbered 2200–2299 and 3200–3219, serving as replacements for the older Armstrong and Dean goods engines while also finding use on short-haul main line and branch passenger trains. These locomotives featured driving wheels of 5 ft 2 in diameter, two cylinders measuring 17½ x 24 in, and a Standard No. 10 boiler operating at 200 lb/sq in pressure, producing a of 20,155 lb and an engine weight of 43 tons 8 cwt. With tenders varying between the GWR's 80 tons 3 cwt design and the ROD type at 91 tons 2 cwt, the class was noted for its relatively large wheels among British tenders, making it the last such design built in Britain. Introduced during a period of modernization for the GWR, the 2251 Class proved versatile and reliable, with wartime builds (Nos. 2211–2230 in 1940) omitting side windows for safety reasons. Withdrawals began in 1958 under British Railways and continued until 1965, with only one example, No. 3205 built in 1946, preserved at the South Devon Railway (as of 2025), having previously operated on the from 1967 to 1987 with guest appearances there in 2000 and 2010.

Design and Development

Origins

The Great Western Railway (GWR), following the 1923 grouping of British railways, faced the challenge of integrating a diverse network of lines, including lightly laid branches in regions like Central Wales, which required reliable and cost-effective locomotives for mixed traffic duties. By the late 1920s, many older tender engines, such as the Dean Goods class, were becoming outdated and inefficient for these secondary routes, prompting the need for a modern successor that could handle medium freight and passenger services without excessive maintenance costs, especially amid the economic pressures of the . In 1930, , the GWR's Chief Mechanical Engineer, designed the 2251 Class as a direct modernization of the Dean Goods, retaining core dimensions like the 5 ft 2 in driving wheels and 17½ in cylinders while incorporating contemporary improvements for better performance and longevity. This design emphasized versatility, enabling the locomotives to operate on both branch lines and shorter mainline hauls, thus addressing the GWR's demand for a multipurpose that could replace aging stock across its expanded system. Drawing on Swindon Works' standardization practices, the class adopted the GWR Standard No. 10 , which featured a taper profile and a single-row to enhance steaming efficiency and overall reliability, marking a shift toward more streamlined production that reduced operational costs. The taper , positioned without a traditional dome, contributed to improved forward visibility from the cab compared to earlier parallel-boiler designs, further supporting the locomotives' adaptability to varied terrains and duties.

Specifications

The GWR 2251 Class locomotives were classified under the as tender engines, featuring driving wheels of 5 ft 2 in (1.575 m) to suit medium-powered freight and mixed-traffic duties. Designed by as an evolution of earlier goods locomotives, they incorporated inside cylinders measuring 17.5 in × 24 in (445 mm × 610 mm), providing enhanced power output compared to predecessors like the Dean Goods. The class utilized the GWR Standard No. 10 , operating at a of 200 psi (1.38 MPa) and delivering a of 20,155 lbf (89.65 kN). This design, with options for 4- or 6-element superheaters, contributed to improved over the Dean Goods through higher and better steam utilization, despite the increased weight restricting some . Key dimensions and weights for the locomotive and tender are summarized below:
ComponentSpecification
Locomotive weight43 long tons 8 cwt (43.3 t)
Tender weight (loaded)36 long tons 15 cwt (37.1 t)
Tender water capacity3,000 imp gal (13,600 L)
Tender coal capacity5 long tons (5.1 t)
These figures reflect the standard Collett tender pairing, though some locomotives received larger ex-ROD tenders during wartime. Additional engineering features included a full cab with side windows and tip-down seats for enhanced protection, particularly on exposed lines, and reversers fitted after initial lever-type setups on early examples. The locomotives were rated GWR Power Class B and later BR 3MT, enabling reliable performance in freight haulage with good acceleration for their size.

Construction

Production Batches

The GWR 2251 Class comprised 120 tender locomotives, all constructed at the Great Western Railway's between 1930 and 1948. Production occurred in eight distinct lots, reflecting phased manufacturing to meet operational needs on lighter branch lines. These locomotives employed standard GWR practices, including framing for the underframes and frames, with no subcontracting to external builders; all assembly, including fitting and tender pairing, was handled in-house at . The initial batch under Lot 261 in 1930 produced the first 20 locomotives, numbered 2251–2270. Subsequent lots followed intermittently, with Lot 283 yielding 10 units (2271–2280) in 1934, Lot 298 adding another 10 (2281–2290) in 1936, and Lot 312 delivering 10 more (2291–2299 and 2200) in 1938. Lot 322 in 1939 built 10 locomotives (2201–2210), while Lot 337 in 1940 completed 20 units (2211–2230).

Construction was halted during due to resource priorities and wartime restrictions, resulting in no new builds from 1941 to 1943; production resumed in 1944 under Lot 347 with adjusted numbering to accommodate conventions. All locomotives adopted the standard GWR No. 10 from the outset, providing consistent steaming performance across batches.

Numbering and Allocation

The GWR 2251 Class locomotives were numbered in three distinct series: the initial batch from 2251 to 2299, covering early builds from 1930 to 1938; the mid-series from 2200 to 2250, constructed between 1938 and 1948; and the series from 3200 to 3219, built from 1946 to 1948. These numbering ranges reflected production lots and avoided conflicts with existing classes. Upon entering service, locomotives were initially allocated to various sheds across the Great Western Railway network, primarily in the Western Region for mixed-traffic duties. Key depots included for London-area operations, for maintenance and local freight, and Plymouth Laira for and routes; additionally, several were assigned to sheds like and Ebbw Junction to handle coal traffic. For example, early batch locomotive No. 2251 was allocated to St Philip's Marsh near , while mid-series No. 2224 went to , and post-war No. 3205 to Horton Road. Following the nationalization of the railways in 1948, the class transitioned to British Railways without significant renumbering, retaining their GWR identities; the 3200–3219 series simply received the BR Western Region prefix 32xx to denote their numbering block. No major reallocation changes occurred immediately after the transition, with most continuing at their pre-1948 sheds until later withdrawals. Build variations included minor differences between early and wartime locomotives, particularly in cab design; those constructed during , such as Nos. 2211–2230 built in 1940, featured windowless cab sides to comply with blackout regulations, though many were later fitted with windows during overhauls.

Operational History

Great Western Railway Service

The GWR 2251 Class locomotives entered service in 1930, primarily tasked with mixed freight duties including the haulage of and general trains, as well as local workings on branch lines. These versatile tender engines were particularly suited to lighter rail infrastructure, replacing older Dean Goods locomotives on routes with moderate gradients and traffic volumes. They saw extensive allocation to depots in , such as and Ebbw Junction, where they handled short-haul freight and services, while also operating in at sheds like and for similar mixed-traffic roles. Although less documented in , their design enabled effective performance on the region's undulating branch lines, supporting essential transport and rural needs. During the 1940s, particularly amid , the class faced significant overload from wartime demands, including essential freight hauls and occasional troop train workings to sustain . To comply with blackout regulations, locomotives from the 1940 batch (Nos. 2211–2230) were constructed without side window openings in their large Collett-style cabs, or had existing windows plated over to prevent light leakage that could aid enemy aircraft navigation. This adaptation, applied across several GWR tender classes including the 2251, ensured operational continuity under strict wartime security measures while maintaining the engines' utility for intensified freight and passenger services. The 2251 Class proved reliable on the GWR's varied and often undulating routes, benefiting from their 5 ft 2 in driving wheels and a of 20,155 lbf, which allowed steady performance on branch lines without excessive wear. However, their classification of 7 (Yellow) limited them to non-electrified lines and restricted mainline access, confining operations to secondary and regional networks rather than high-speed or heavy-traffic corridors. This positioning enhanced their longevity in everyday duties, with no major class-wide modifications required throughout GWR ownership. By the end of , over 100 locomotives of the class were in active service, reflecting peak usage during and as production ramped up to meet growing freight and passenger needs. Allocated across key western depots, they maintained high availability for routine operations, underscoring the class's role as a dependable workhorse until in 1948.

British Railways Service

Upon in 1948, the GWR 2251 Class was absorbed into British Railways' Western Region, where the existing fleet of 118 locomotives continued their established mixed-traffic duties without immediate major changes. Two further examples, Nos. 3209 and 3218, were completed at that year, representing the final batch of tender locomotives constructed in Britain. Under BR, the class remained versatile for lighter freight and passenger relief workings, particularly suited to steeply graded branch lines due to their high tractive effort relative to size and good acceleration capabilities. Allocations were widespread across the Western Region but concentrated in South West England, including depots at Laira (Plymouth), Plymouth Friary, Newton Abbot, and Exmouth Junction, as well as sites like Worcester and Machynlleth for regional traffic. For instance, locomotives such as No. 3205 operated freight services from these bases, occasionally handling summer passenger turns on lines like the Severn Valley Branch. To align with BR standards, several members received updates in the , alongside tenders swapped from withdrawn Railway Operating Division (ROD) stock for extended range. The class's numbers began declining from the late 1950s amid accelerating dieselization and programs, which prioritized modern traction over steam for branch and relief services; by the end of , 23 remained in service.

Withdrawal

The withdrawal of the GWR 2251 Class locomotives began in December 1958 with No. 2258, which had been stored at prior to decommissioning. This marked the start of a phased decommissioning process under British Railways' broader steam elimination program, driven by the 1955 Modernisation Plan that prioritized diesel and electric traction to modernize freight operations. The class's stemmed from their for medium-powered freight, which became inefficient compared to emerging diesel shunters like the Class 08 and later the Class 14 locomotives introduced in for similar short-haul duties. By the early 1960s, surviving examples were relegated to short-haul freight workings, particularly in the around depots such as and Plymouth Friary, with no involvement in mainline passenger services after as larger locomotives and diesel units took over those roles. Withdrawals accelerated through 1962–1964, with locomotives stored at before scrapping; of the 120 built, 119 were ultimately scrapped, primarily at . The final withdrawals occurred in 1965, with 13 locomotives taken out of service that year, including No. 2210 at in June. Notably, No. 3205, withdrawn in June 1965 after allocation to , was acquired directly by the 2251 Fund for preservation, averting scrapping and becoming the sole survivor of the class.

Preservation and Legacy

Preservation

The sole surviving member of the GWR 2251 Class is locomotive No. 3205, constructed at in 1946 and withdrawn from British Railways service in 1965. It was acquired for preservation by the 2251 Fund, with principal trustee David Rouse, and became the second locomotive to arrive at the newly formed Dart Valley Railway (now the South Devon Railway) at later that year. In its preserved career, No. 3205 operated across multiple heritage lines, including the Severn Valley Railway from 1967 to 1987—where it hauled the line's first public passenger train in 1970—and the West Somerset Railway, before transferring back to the South Devon Railway in 1998. It returned to traffic following a heavy overhaul in May 2010, painted in British Railways lined green livery, and remained operational on the South Devon Railway until withdrawn again in 2017 due to a cracked boiler. No. 3205 was last steamed in October 2020 prior to further assessment for overhaul. The required work includes a new cylinder block, major repairs approaching a full replacement, and other heavy maintenance, with costs estimated at £300,000 to £400,000; these challenges are compounded by the locomotive's status as the only preserved example of the class, providing unique representation of Collett's goods design. In October 2023, the South Devon Railway secured a 50-year custodianship agreement with the 2251 Locomotive Fund, ensuring the locomotive's long-term basing at while the railway funds and oversees the restoration. A share issue was launched concurrently to raise funds for returning No. 3205 to operational condition, with a target completion in the late 2020s. As of November 2025, boiler work remains in progress amid ongoing fundraising efforts.

Models

In OO gauge, ready-to-run models of the GWR 2251 Class are produced by Bachmann, featuring DCC-ready sockets, couplings, and options for detailed weathering to represent operational wear. Earlier toolings from Mainline, now under Bachmann, along with kits, offer buildable alternatives for modelers seeking customization. For N gauge, provides ready-to-run locomotives with DCC-equipped variants, emphasizing smooth running and period-appropriate details. Union Mills kits focus on and liveries, such as GWR green and early BR black, suitable for mixed-traffic scenarios. In other scales, TT gauge options include white metal kits from BEC, designed for assembly on compatible . O gauge models are rare in ready-to-run form, leading enthusiasts to scratchbuild or use etched kits like those from Brassmasters for high-fidelity replicas. These models commonly incorporate working inside motion for realistic animation, finely detailed tenders with coal and water representations, and variants depicting GWR unlined green or BR black liveries to match different service eras. While digital sound enhancements exist for simulators via projects like Steam Sounds Supreme, physical models often rely on aftermarket DCC sound decoders to fill gaps in authentic audio reproduction. The 2251 Class models enjoy popularity in British outline modeling, particularly for recreating and light freight operations due to their compact size and historical versatility.
