J 50/51 arriving Queensbury with a goods in the fities shortly before closure of the line.
Intended for the West Riding, the initial J50 and J51 allocations were to Ardsley, Bradford, and Copley Hill. These engines were used for local goods and coal workings, with shunting at intermediate yards. There were also used for shunting the larger West Riding marshalling yards. During the 1920s, they were also occasionally used for passenger work, and for banking duties.
All of the J50s survived to Nationalisation (1948), when the allocations were to Ardsley, Bradford, Copley Hill, Doncaster, Colwich, Frodingham, Stratford, Woodford, Annesley, Sheffield, St. Margaret's, and Eastfield. Most were still allocated in the West Riding, with lesser numbers further afield.
