The 4F was based on the 197-strong Midland Railway 3835 Class of 1911, with only a few modifications, primarily the adoption of left-hand drive instead of right-hand drive. They originally had been designed by Henry Fowler, who from 1925 became CME of the LMS.
Midland Railway locomotives were notorious for their short axle-box bearings, which were prone to overheating. This design feature was perpetuated in the LMS 4F. The problem was eventually solved with the fitting of mechanical lubricators.[citation needed]
Construction
The LMS constructed 530 of the locomotives between 1923 and 1928, numbered sequentially from where the Midland engines left off from 4027. A further 45 examples were reluctantly authorised by William Stanier in 1937 at the behest of the operating department.
All entered British Railways stock in 1948. BR added 40000 to their numbers. They were all withdrawn between 1959 and 1966.
Accidents and incidents
On 12 February 1929, locomotive No. 4491 was hauling a freight train that was in a head-on collision with an express passenger train, hauled by LNWR Claughton Class4-6-0 No. 5977, at Doe Hill station, Derbyshire due to a signalman's error. Two people were killed.[2]
On 4 September 1942, locomotive No. 4541 was hauling a freight train that overran the end of a loop in blackout conditions at Todmorden, Yorkshire and was derailed.[3]
On 6 June 1961, a locomotive of the class was running light when it was in a head-on collision with a freight train at Carlisle Citadel station, Cumberland.[3]
Withdrawal
Withdrawals from stock occurred between 1959 and 1966.
Under overhaul. Returned to the CVR in December 2019 following the termination of its previous loan agreement with the West Somerset Railway.
Models
The 4F has been modelled by Lima (O gauge, HO gauge and British N gauge) and Graham Farish (British N Gauge, still produced under the Bachmann label). Airfix produced a tender drive model of the 4F in OO gauge in 1978. Production of this was continued by Dapol after it acquired Airfix models in 1985, and were subsequently sold to Hornby in the late 1990s. They upgraded the model with an improved chassis in 2012.[6]Bachmann have produced a version of the Midland railway variant of the 4F since 2012.
