The V4 Class 2-6-2 was Sir Nigel Gresley’s last design for the LNER, as a mixed traffic locomotive, before he died in 1941. Two in total were built at Doncaster in 1941: No. 3401 and 3402. No. 3401 was named Bantam Cock to highlight the lightweight nature of the design but No. 3402 was never officially named, however it acquired the unofficial name of Bantam Hen. Following Gresley’s death, the Class was discontinued.
