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

Overview[edit]

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.

Models[edit]

Hornby produce a 00 gauge model based on the old Dapol (formerly Airfix) tooling which is reasonably accurate.[1] Graham Farish produced an N gauge model of the 4P 4-4-0 Compound when they were in Poole, Dorset, and the chassis for this could be modified to represent the 2P. Union Mills on the Isle of Man make a 2P in N gauge.
