LNER Thompson Class B1 (6)1264

London and North Eastern Railway Thompson Class B1 No. 1264, later British Railways No. 61264 and Departmental No. 29, is a preserved British steam locomotive. It was built in 1947 by the North British Locomotive Company, works number 26165, and was first allocated to Parkeston Quay near Harwich for the Great Eastern Main Line, where it stayed for 13 years. It passed to British Railways in January 1948 and was withdrawn in December 1965. Rescued from scrap in 1973 as the 83rd engine to leave Barry, it was the last surviving ex-LNER locomotive not preserved. It moved to the North Yorkshire Moors Railway after overhaul and was withdrawn again in 2020 when cracks were found in the firebox.
