Steam Locomotives of British Railways - BR 'Standard' Classes

BR 'Standard' Classes

From 1951, BR started to build steam locomotives to its own standard designs, which were largely based on LMS practice but incorporating ideas and modifications from the other constituent companies, and America. Their design was overseen by Robert Riddles.

Characteristic features were taper boilers, high running plates, two cylinders and streamlined cabs.

Although more were ordered, 999 BR "Standards" were constructed: the last, 92220 Evening Star, was built in 1960. Most never achieved their potential service life and were withdrawn in working order.

The tenders used with the Standard locomotives were also new designs. There were different types were due to different coal-to-water ratios, weight restrictions, and later improved designs.

Famous quotes containing the word classes:

    I have no doubt but that the misery of the lower classes will be found to abate whenever the Government assumes a freer aspect and the laws favor a subdivision of Property.
