The London, Midland and Scottish Railway Class 2P 4-4-0 was a class of steam locomotive designed for light passenger work.
Overview
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.
