The class was introduced in 1906 as a replacement for the GCR Class 4dock shunters, based on his predecessor’s GCR Class 5 but with side tanks rather than saddle tanks. A seventh locomotive was built in 1914.
All seven examples survived into British Railways ownership in 1948, at least one being at Immingham in 1952, and at least one at Connah's Quay in 1954. They were all withdrawn between 1953 and 1957.
