Great Northern Railway Class BT were a class of 13 4-4-0 T tank locomotives introduced by the GNR(I) from 1885.^[1]

While fit for purpose when built, increasing train weights particularly with bogie carriages a factor meant by the 1920s they were underpowered for all available work and were withdrawn by 1921.^[2]
