TheGreat Central RailwayClass 11F orImproved Director Class is a class of4-4-0steam locomotive designed byJohn G. Robinson for passenger work. TheLNER classified them asClass D11 in 1923. They were based on the earlierGCR 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 inScotland.^[2]

The 11F Class was initially used on passenger work on the GCR system, including fast expresses fromSheffield Victoria toLondon Marylebone. Later in their careers, they were used on short-distance passenger trains. On lines of theCheshire Lines Committee during the late 1940s and early 1950s, they hauled expresses betweenManchester Central andLiverpool Central; also semi-fast trains from Manchester Central via Northwich toChester Northgate.

Their 6 ft 9 inches driving wheels made them fast locos, but consequently unsuitable for hauling freight trains. The eleven original 11F locos were withdrawn during 1959 and 1960 as diesel multiple units took over operation of the shorter distance passenger trains. The final Scottish D11/2 was withdrawn in January 1962.^[3]

The sixth member of the class, No. 506Butler-Henderson, was withdrawn from use by British Railways during 1960. It has been preserved as part of theUK National Collection and currently wears restored GCR colours. No. 506 is the only surviving GCR passenger locomotive.

The locomotive operated passenger trains on the preservedGreat Central Railway inLeicestershire during the late 1970s, 1980s and early 1990s but is now out of running order. The locomotive was placed on long-term loan for static display atBarrow Hill Engine Shed, nearChesterfield, in 2005, where she currently resides.^[4]

In 2012,Bachmann Branchline introduced models of the D11 in other Great Central liveries, LNER liveries and British Railway liveries.^[5] In 2012, Bachmann produced an exclusiveOO gauge model of No. 506Butler-Henderson for theNational Railway Museum shop, as a hundred-piece limited edition in Great Central livery.^[6][7] Bachmann's general production run of the model totalled 1,500.^[8]
