in October 1871, were sold to the LYR in November 1871. Crewe numbers 1489–98, 1532–41, 1602–21 and 1722–61 (total 80) were delivered new to the LYR. Most of those built from 1872 onwards (total 130) incorporated modifications by Francis Webb such as being fitted with cabs. From April 1881, Webb rebuilt 500 examples with a new 150 psi boiler and vacuum brakes for working passenger trains. These became known as ‘Special’ (or vacuum) DX’s. Accidents and incidents On 12 January 1899, locomotive 1418 was hauling a freight train that was derailed at Penmaenmawr, Caernarfonshire due to the trackbed being washed away in a storm. Both locomotive crew were killed. Withdrawals Withdrawals began in 1902, but there were still 88 engines in existence at the time of the London, Midland and Scottish Railway's formation in 1923. The last survivor was withdrawn in 1930. Despite the large number of the class produced, all were scrapped. Engines converted to other uses The chassis of a withdrawn DX Goods locomotive was repurposed as a stationary engine on the Sheep Pasture Incline of the Cromford and High Peak Railway in February 1884 but was replaced by an electric winch in 1964. Engines sold abroad Between 1900 and 1901, four LNWR Special DX were sold to the Société Anonyme du Chemin de Fer International de Malines à Terneuzen, a private railway between Belgium and the Netherlands. They were renumbered 15, 16, 17 and 18. Three of them were rebuilt between 1910 and 1911 with larger cabs of Belgian design and all of them were fitted with Westinghouse brakes sometimes after 1911. One of them (number 15) was still on the active roster in 1948 when the Malines - Terneuzen was taken over by SNCB. All the M.T. engines were then scrapped.
