LMS Fowler Class 4F
44444 at Stockport, 1950
The London Midland and Scottish Railway (LMS) Fowler 4F is a class of 0-6-0 steam locomotive designed for medium freight work. They represent the ultimate development of Midland Railway's six coupled tender engines. Many trainspotters knew them as "Duck Sixes", a nickname derived from their wheel arrangement.
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.
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.
|LMS nos.||BR nos.||Lot No.||Date built||Built by|
|4057–4081||44057–44081||8||1925||North British Loco|
|4382–4399||44382–44399||33||1926||North British Loco|

All entered British Railways stock in 1948. BR added 40000 to their numbers. They were all withdrawn between 1959 and 1966.

The 4F has been modelled by Lima (O, OO, HO and N Gauge) and Graham Farish (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 to loco drive in 2012. Bachmann have produced a version of the Midland railway variant of the 4F since 2012.
