Barton Wright introduced his standard 0-6-0 in 1876 and a total of 280 were built up to 1887. When Aspinall built his 0-6-0s in 1889 (class 27 engines), many of these engines became surplus to requirements and all except the last fifty were rebuilt as saddle tanks becoming the 51307 or 23 class.

At the time the locomotives were converted to saddle tanks the L&YR had an acute shortage of shunting engines. 230 were rebuilt between 1891 and 1900. 96 of these engines came into BR stocks numbered in the range 51307-51530 plus service engines numbered in the range 11304-11394.
The engines were withdrawn from 1930 onwards and twenty-five of the un-rebuilt fifty survived to become BR locomotives in 1948. Of these twenty-five which were all built in 1887, ten had been built by Vulcan Foundry Ltd and fifteen by Beyer Peacock & Co Ltd. The original 230 had been built by a wide range of manufacturers as L&YR did not have Horwich to build locomotives until 1889.
As at 1st January 1948 they were allocated as follows.
