4-6-0 Class B1 Thompson LNER Profile and Models

The Class B1 was designed by Edward Thompson for use on medium mixed traffic work on the LNER network. A huge number were built as the class were the equivalent to the highly successful GWR Hall and LMS ‘Black Five’ classes. The class had to be built to a budget due to WWII and post-war economies. The class were named after breeds of antelope which led to them being known as “Bongos”. The class were found to be all-round good performers and operated across LNER territory on all manner of freight and passenger services.
