The GCR Class 8C was a class of a pair of 4-6-0 locomotives built for the Great Central Railway in 1903–1904 by Beyer, Peacock and Company. They passed to the London and North Eastern Railway at the 1923 grouping and received the classification B1. Following the introduction of Thompson's B1s, they were reclassified B18 in 1943 and both were retired in 1947.
