One hundred and ninety five engines were built by the LMS, adding to the 45 Midland Railway 1000 Class, to which they were almost identical.The most obvious difference is that the driving wheel diameter was reduced from 7 ft 0 in (2.134 m) on the Midland locomotive to 6 ft 9 in (2.057 m) on the LMS version.
The class was introduced in 1928 and was a post-grouping development of the Midland Railway 483 Class with modified dimensions and reduced boiler mountings.. The numbering continued from where the Midland engines left off at 563 and eventually reached 700. 138 were built, though numbering is slightly complicated by renumberings and transfers.
The classification was made up of a number (representing the power output - 0 being low power and 9 high power) and a letter (representing the type of work the locomotive was intended for), e.g. 4F. Over the years there were some modifications to the system, but the basics remained the same.
The Midland shaped the subsequent LMS locomotive policy until 1933. Its locomotives (which it always referred to as engines) followed a corporate small engine policy, with numerous class 2F, 3F and 4F 0-6-0s for goods work, 2P and 4P 4-4-0s for passenger work, and 0-4-4T and 0-6-0T tank engines.
The London, Midland and Scottish Railway (LMS) 2 and 2A boilered 4-6-0 locomotives were express passenger 4-6-0 steam locomotives. In 1935, William Stanier , Chief Mechanical Engineer of the LMS, ordered the rebuilding of the unique experimental high pressure compound locomotive 6399 Fury .
The ex-MR 2F 0-6-0s that had not been rebuilt as 3Fs were also renumbered into that series, as were the Midland 1P 0-4-4T. It then took a few years to renumber all the locomotives. In terms of locomotive taxonomy, the LMS had a tendency to lump classes together (e.g. Sentinels, diesel shunters, ex-Midland 0-4-4Ts), but for clarity these have ...
This design was based on the earlier Stanier LMS Stanier 2-6-4T, which was derived from Henry Fowler's LMS Fowler 2-6-4T engine. Fairburn modified the design to have a shorter coupled wheelbase, reduced from 16 ft 6 in (5.03 m) to 15 ft 4 in (4.67 m) allowing curves of 5 chains to be negotiated; to reduce the locomotives mass per unit length the overall weight was reduced by 3 long tons 8 cwt ...
