Standard 4 – tanks
On nationalisation in 1948, British Railways inherited a number of ex LMS 2-6-4T and Great Western 2-6-2T which were particularly suited to commuter and secondary routes but in Scotland and the Southern Region, they were struggling on with pre-grouping designs. The decision was therefore made to build a number of standardised designs of which the Type 4 tank engine was one. A total of 155 were built with the majority being constructed at Brighton.
15 members of the class have made it into preservation and are fairly widely spread across the country. Here we see number 80104 running around its train at Swanage Station on 30 March 2018.

Standard Class 9F
The 2-10-0 was a class of engine designed by Robert Riddles primarily for fast, heavy freight workings. Appearing from the 1950s onwards, they were probably one of the most powerful engines ever to work on the British Railways network. A total of 251 were built of which the final one, 92220 Evening Star built in 1960 was painted in passenger Brunswick Green livery and entered the National Railway Museum ownership after just five years of operating service.
9 examples have survived into preservation.
Here are two examples, 92203 Black Prince which is based on the North Norfolk Railway seen on 27 March 2016, and 92214 seen running on the Severn Valley Railway at their Spring Gala on 18 March 2017 on loan from its normal base, the Great Central Railway.
