There were two subclasses: D11/1 were the original GCR engines and D11/2 were those built in 1924 by the LNER to a reduced loading gauge with smaller boiler mountings for hauling passenger trains in Scotland.

[2] The 11F Class was initially used on passenger work on the GCR system, including fast expresses from Sheffield Victoria to London Marylebone.

The eleven original 11F locos were withdrawn during 1959 and 1960 as diesel multiple units took over operation of the shorter distance passenger trains.

The locomotive operated passenger trains on the preserved Great Central Railway in Leicestershire during the late 1970s, 1980s and early 1990s but is now out of running order.
