Английская Википедия:GWR 5101 Class
Шаблон:Use dmy dates Шаблон:Use British English Шаблон:About Шаблон:Infobox Locomotive The GWR 5101 Class or 'Large Prairie' is a class of 2-6-2T steam locomotives of the Great Western Railway.
History
The 5101 Class were medium-sized tank engines used for suburban and local passenger services all over the Great Western Railway system. The class was an updated version, by Collett, of Churchward's 1903 3100/5100 Class.
The original 40 members of the 3100 class were renumbered 5100 and 5111 to 5149 in 1927. The first batches of 5101s filled in the numbers 5101 to 5110 and extended the class from 5150 to 5189. They were little changed from the Churchward locomotives as they then were, but had an increased axle loading of Шаблон:Long ton; the maximum permitted for the ‘Blue’ route availability. Bunkers were of the standard Collett design with greater coal capacity. The 5100 number series was exhausted in 1934, and further new locomotives were numbered from 4100. The last 20 were built after nationalisation.[1]

As both freight and passenger traffic on branch lines declined post-World War II with increasing volumes of private motor cars, and replacement on urban services by diesel-powered rail cars, the bulk of the class found itself allocated to various mainline support duties, mainly banking and piloting, often on the South Devon Banks on the Exeter to Plymouth Line, or around the Severn Tunnel on the South Wales Main Line.
A number of the class - 4110, 4115, 4121, 4144, 4150, 4156 and 4160 - ended their operational lives allocated to the major locomotive shed (88E) at Шаблон:Stnlnk, undertaking piloting and banking duties through both the Severn Tunnel and the associated goods yard.[2] Assistance was needed by all heavy trains through the Severn Tunnel, which entailed: Шаблон:Convert of 1-in-90 down to the middle of the tunnel; then a further Шаблон:Convert at 1-in-100 up to Шаблон:Stnlnk; a short level then Шаблон:Convert more at 1-in-100 to Шаблон:Stnlnk. However, the pilot locomotive usually came off at Pilning. Several of this group were sold for scrap to Woodham Brothers and consequently have survived into preservation.
Accidents and incidents
- On 30 November 1948, locomotive 4150 was running round its train at Шаблон:Rws when it was in collision with a passenger train hauled by 5022 Wigmore Castle, which had overrun signals.[3] Eight passengers were injured.[4]

Preservation
Ten of the class were preserved after withdrawal in the 1960s (six built in the 1930s before World War II and four built after the war in the late 1940s, one of which under the British Railways banner). As of 2023, six have run in preservation, one is under restoration, one is still in scrapyard condition, one has acted as a donor locomotive for other projects, and one has been rebuilt into a tender engine:

Models
Graham Farish manufacture a model of the Large Prairie in N scale. Hornby have manufactured two models of the class in 00 gauge in both Great Western and British railway liveries; the first was based on a 1980's Airfix model of the engine, the second was a 2020 re-tooled model with a 5 pole motor. Dapol have a 00 gauge model due for release in q4 2021; this has both GWR and BR livery versions planned. Heljan are planning on producing a model of the large prairie in O gauge in 2017.[11] Sonic Models have announced they producing an N scale model, due for release in April/May. [12]
