S&DJR No 88 runs round its train at Minhead
The Somerset and Dorset Joint Railway (S&DJR) 7F 2-8-0 is a class of steam locomotive designed for hauling heavy coal and goods trains. Eleven were built in two batches in 1914 and 1925, and were used until withdrawn between 1959 and 1964. Two are preserved.
Both met for the first time in preservation at the West Somerset Railway during the next month, after No. 89 made a return to Bath Green Park Station over 5 and 6 March 2006, 40 years after the S&D closed.
