British Rail Class D20/2

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The British Railways Class D600 diesel-hydraulic locomotives were built by the North British Locomotive Company in Glasgow during 1957 and 1958. Although never assigned a TOPS class as they were withdrawn before TOPS was introduced British Loco enthusiasts coined the term "Class 41". All were named after Royal Navy vessels, hence the nameplates each bore a subtitle "Warship Class". The fleet was ordered by the British Transport Commission as direct comparison with British Rail Class 40, and were not actually wanted by the Western Region, who preferred their production fleet of D800 Warships.
