The GCR Class 1 was a class of steam locomotives designed by John G. Robinson for the Great Central Railway, and introduced to service between December 1912 and 1913. In the 1923 grouping, they all passed to the London and North Eastern Railway which placed them in class B2. Their classification was changed to B19 in 1945, and all had been retired by the end of 1947.
