GCR Class 8A

The Great Central Railway (GCR) Class 8A was a class of 0-8-0 steam locomotive built between 1902 and 1911 for handling heavy coal trains over the Pennines. They all passed to the LNER in 1923, who redesignated them Class Q4. They were withdrawn from service between 1934 and 1951. Between 1942 and 1943, thirteen were rebuilt as 0-8-0T by Edward Thompson (engineer) and reclassified as Class Q1.
