Changes

British Railways (BR) assigned Class 52 to the Type 4 diesel-hydraulic locomotives built between 1961 and 1964 for BR(W). They carried numbers D1000-D1073, but never carried a TOPS locomotive number. All were given two-word names beginning "Western", hence the type became known as 'Westerns' or 'Thousands'.

D1062 Western Courier was built at Crewe Works and entered service at London’s Old Oak Common shed on 6 May 1963. D1062 also served at Cardiff Canton, Swansea Landore and Plymouth Laira, and was withdrawn from the latter by BR on 23 August 1974 after 1,096,000 miles in service.Courier was an early withdrawal but was lucky enough to share 'mascot' duties with Class 42 Warship 818 Glory, being placed on the turntable at Swindon works and given a repaint by the apprentices.

The WLA overhauled D1062 between 1998 and 2005 including major rewiring. On 29 April 2005 the HLF granted the WLA £45,500 towards Western Courier's overhaul, which was used for sending a defective Voith transmission to the manufacturer in Germany.<ref>[http://www.lotterygoodcauses.org.uk/good-causes/projects/region/west-midlands?project_name=Western%20Locomotive&op=Refine&form_build_id=form-S9K5ipVWQ_b_PxmypsoqH8-m2G1rwl0DsjWvXdu2D0M&form_id=directory_finder_refine_form The National Lottery]</ref>. In 2017 she was repainted into BR blue livery in the [[Diesel Depot]] for the first time in preservation. She also made use of the Depot in the winter of 2017-2018 for or engine work and a bogie lift, making use of the new jacks. {{As  The class's method of | 2018}}construction precludes locomotives being winched onto and off road trailers, D1062 is in available for regular service on and so moves off the SVR, her 40th anniversary on the railwayare exclusively being hauled by rail. The locomotive's [[TOPS codes#TOPS_locomotive_classification_and_numbering|TOPS code]] is 89462.
