London, Chatham and Dover Railway

The London, Chatham and Dover Railway (LCDR) was a railway company in south-eastern England from 1859 until the 1923 grouping which united it with other companies to form the Southern Railway. Its lines ran through London and northern and eastern Kent to form a significant part of the Greater London commuter network. From the start the railway was in an impecunious position.

The Chatham, as it was always known, was much criticised for its often lamentable carriage stock and poor punctuality, but in two respects it was very good: it used the highly effective Westinghouse brake on its passenger stock, and the Sykes 'Lock and Block' system of signalling. It had an excellent safety record.
