what is it?

The London and North Eastern Railway (LNER) Thompson Class B2 was a class of 4-6-0 steam locomotive. It was introduced in 1945 as a two-cylinder rebuild (with diagram 100A boiler) of the three-cylinder LNER Class B17. Ten were rebuilt from Class B17 but no more were rebuilt because of the success of the LNER Thompson Class B1.
