LMS 1000X / BR Class D16/1

British diesel locomotive created in 1947 by LMS Derby Works. It was the first diesel locomotive built in Great Britain. It was first introduced on 18 December 1947 at London Euston Station on a journey to Watford Station. Three months later it was purchased by British Rail and, together with the 1948-built 10001 locomotive, it ran on the London Euston-Carlisle-Glasgow line. In the same year it was tested on the London St. Pancras to Manchester Central Station route and on the London-Derby and Derby Manchester routes. From 1949 it operated between London Euston and Glasgow as part of the "Royal Scot" train and on the London Euston-Blackpool, London Euston-Crewe-Liverpool and Settle-Carlisle routes. From 1953 it ran on the Southern line, as a counterweight to the newer 10200 Series locomotives. In the late 1960s both locomotives were withdrawn and scrapped. In 2011, the Ivatt Diesel Re-creation Society announced that it had decided to build a replica using the engine and running gear of a Class 58 locomotive. The locomotive itself became a milestone for subsequent diesel locomotives in the UK.
