B 4-6-0 Tender

LNER 4-6-0 Locomotives

Only three of the LNER's constituent companies had 4-6-0 locomotives ("Ten-Wheelers" in American railroad jargon) at Grouping in 1923. Unlike his contemporaries, Gresley does not appear to have liked the wheel arrangement. Other than the building of 52 locomotives of pre-existing 4-6-0 classes, he would only introduce one 4-6-0 class: the B17 Sandringham Class for use on former Great Eastern Railway (GER) routes.

Thompson's standardisation programme included a conventional 4-6-0 mixed traffic class in the form of his Class B1. Construction of the Thompson B1s would continue into BR ownership and they became the most numerous 4-6-0 LNER class.
