Class B13) was a
4-6-0 type of
steam locomotive designed for express passenger workings. The first example was built in 1899. They were very similar to the
NER Class S1, except for the smaller wheels of the former.
Design
They were designed to reduce
double heading
In railroad terminology, double heading indicates the use of two locomotives at the front of a train, each operated individually by its own crew. The practice of triple-heading involves the use of three locomotives. The practice of multi-headi ...
on the
East Coast Main Line. However they steamed poorly, with a smaller and shallower grate than was used even by other locomotives at the time, and the
4-4-0s of the
NER Class R quickly replaced them, with the
4-4-2 layout being preferred for later express passenger designs. The class were re-classified as
London and North Eastern Railway Class B13 in 1923.
Modifications
The first seven locomotives had
slide valves, while the remainder had
piston valves
Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive. They control the admission of steam into the cylinders and its subsequent exhausting, enabling a locomotive to move under its own power ...
. The slide valve engines were later fitted with piston valves. Schmidt
superheaters were fitted between 1913 and 1925.
Numbering
Withdrawal
They were withdrawn between 1928 and 1938.
