LMS Compound 4-4-0

The London, Midland and Scottish Railway Compound 4-4-0 was a class of steam locomotive designed for passenger work.

Overview

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 on the Midland locomotive to on the LMS version. They were given the power classification 4P.

The LMS continued the Midland numbering from 1045 to 1199 and then started in the lower block of 900–939. After nationalisation in 1948, BR added 40000 to their numbers so they became 40900–40939 and 41045–41199.

Accidents and incidents

• On 8 January 1929, locomotive 1060 was hauling an express passenger train from Bristol to Leeds, Yorkshire when it overran signals at Template:Rws, Gloucestershire and collided with a freight train that was being shunted. Four people were killed.
• On 13 March 1935, locomotive No. 1165 was hauling a milk train that was in a rear-end collision with an express freight train, hauled LNWR Claughton Class 4-6-0 No. 5946, at King's Langley, Hertfordshire due to a signalman's error. Two other freight trains collided with the wreckage. One of these trains was hauled by LMS Patriot Class 4-6-0 No. 5511 and the other was a coal train, being hauled by LMS Class 7F 0-8-0 No. 9598. 1 person was killed.

Withdrawal

The class were withdrawn between 1952 and 1961. None have survived into preservation, though the first of the Midland 1000 Class engines has. There is an unconfirmed report that No. 41168 was the subject of an unsuccessful preservation attempt by Dr. Peter Beet.
