British Railways Standard Class 7MT 4-6-2 No 70000
'Britannia' departs New Street station on an up express on 22nd June 1963.
Designed by Robert Riddles for use by British Railways for mixed traffic duties
some fifty-five members of the class were constructed between 1951 and 1954.
The design was a result of the 1948 locomotive exchanges undertaken in advance
of further locomotive classes being constructed. The fifty-five members of the
class were built in three batches by Crewe works prior to the publication of
the 1955 Modernisation Plan. The Britannia Class was based on several previous
locomotive designs, incorporating the best practices in locomotive technology
as regards labour-saving and lowering maintenance costs; various weight-saving
measures also increased the route availability of a Pacific-type locomotive on
the British Railways network. The Britannias received a positive reception from
their crews, with those regularly operating the locomotives giving them
favourable reports as regards performance. However, trials in some areas of the
British Railway network returned negative feedback, primarily due to
indifferent operation of the locomotive, with its effects on adhering to
timetables. The Britannias took their names from great Britons, former Star
Class locomotives, and Scottish firths. The class remained in service until the
last was withdrawn in 1968. Two survived into preservation, the first-of-class
No 70000 Britannia, seen above, and No 70013 Oliver Cromwell.
