The
South Eastern and Chatham Railway Companies Joint Management Committee (
SE&CRCJMC), known as the
South Eastern and Chatham Railway (
SE&CR), was a working union of two neighbouring rival railways, the
South Eastern Railway (SER) and
London, Chatham and Dover Railway (LC&DR), which operated between London and south-east England. Between 1899 and 1923 the SE&CR had a monopoly of railway service in Kent, and to the main Channel ports for ferries to France and Belgium.
