The War Department
(WD) "Austerity" 2-10-0
is a type of heavy freight steam locomotive
that was introduced during the Second World War
The Austerity 2-10-0 was based on the Austerity 2-8-0
, and was designed to have interchangeable parts by R.A. Riddles
. It had the same power output as the 2-8-0 but a lighter axle load
, making it suitable for secondary lines.
It had a parallel boiler and round-topped firebox. While the 2-8-0 had a narrow firebox, the 2-10-0 had a wide firebox placed above the driving wheels. This arrangement was common in the USA
(e.g. the USRA 0-8-0
) but unusual in Britain. In Britain, wide fireboxes were usually used only where there was a trailing axle, e.g. in 4-4-2
types. One exception was the GER Decapod
These were the first 2-10-0
locomotives to work in Great Britain, and the first major class of ten-coupled engines — they had been preceded by two 0-10-0
locomotives; the Great Eastern Railway
and the Midland Railway

The 2-10-0 wheel arrangement was later used by Riddles when he designed the BR standard class 9F
. This, too, had a wide firebox placed above the driving wheels.
Two batches were built by the North British Locomotive Company
, the first batch of 100 introduced in 1943/1944 and the second batch of 50 in 1945. Their WD Nos were 73650–73799.
20 of the first batch were sent to the Middle East
. During running-in they worked in Britain, but... Read More
