LNWR Class A
Encyclopedia
The London and North Western Railway
(LNWR) Class A was a class of 0-8-0
steam locomotives. From 1893 to 1900, Crewe built 111 of these engines, which had a three cylinder compound
arrangement, and were designed by Francis Webb
.
Like the other Webb compounds, they proved problematic, so in 1904 George Whale
began rebuilding these to simple expansion engines. Fifteen were converted to Class C
between 1904–1906, 62 to Class D
between 1906–1909, with the remaining 34 rebuilt by Charles Bowen Cooke to Class C1
between 1909-1912.
The LNWR letter classification system for 8 coupled engines was introduced in 1911.

A compound engine unit is a type of steam engine where steam is expanded in two or more stages.A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger...
