| Lifetime |
1919—1933 |
In common with many railways, after the First World War the LNW
purchased thirty 2-8-0’s which had been ordered for
use by the Railway Operating Division (ROD  ) on the Western Front.
Previously 151 had been hired from 1919—1921. They were
classed ‘MM’s’ after the Ministry of Munitions
which had ordered them but enginemen irreverently named them
‘Military Mary’s’. There was not thought to have
been a specific Mary, simply a play on words, unless they were a Mary
‘quite contrary’.
The design had originally come from the Great Central Railway (8K
class) and had been chosen for mass production during the war for its
power and ruggedness. With two 21in diameter outside cylinders,
153 sq.ft. grate area, 180 psi boiler pressure and eight
4ft 8in driving wheels it was a powerful engine for the
time. Not such an effeminate Mary, then.
