After WWII the existing railway companies were all put into the control of the newly formed British Transport Commision & that government organisation spawned British Railways which came into being on 1st January 1948. The railway infrastructure had suffered badly during the war years & most of the steam locomotives were 'tired' & badly maintained & or life expired. Although the management of British Railways was already planning to replace steam power with diesel & electric engines/units they still took a decission to build more steam locomotives (as a stop gap). Some 999 (yes just 1 short) Standard locomotives were built in 12 classes ranging from super powerful express & freight engine to suburban tank locomotives. The locomotives were mainly in good order when the order came in 1968 to end steam some only 8 years old. There still exists a fleet of 46 preserved Standards of which 75% are in working order in & around the UKs preserved railways furthermore 3 new build standard locomotives are proposed. Steam fans who were around in the 1960s all remember the ' Standards'.
