Invention and Engineering
The Great Central Railway Class 11F or Improved Director Class is a class of 4-4-0 steam locomotive designed by John G. Robinson for passenger work. The LNER classified them as Class D11 in 1923. They were based on the earlier GCR Class 11E "Director" class (LNER D10). 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.
