LNER Thompson B2 Class

The LNER Thompson B2 Class designation in this database refers to Edward Thompson's rebuilds of Gresley's B17 Class 4-6-0 'Footballer' express locomotives, which are covered in the main LNER B2 Class entry. The Thompson B2 Class represents the same locomotives — the controversial Thompson two-cylinder rebuilds of the Gresley B17 Footballers that replaced the three-cylinder conjugated valve gear with outside Walschaerts-operated cylinders.

See the LNER B2 Class entry for the full design history, service record, and preservation status of the Thompson B2 rebuilds.
