which resulted in the formation of the South Eastern and Chatham Railway (SE&CR). This was not a true merger since each company kept its individual board of directors within the organisation. The rolling stock and steamboats of the two companies were thereafter worked as one concern. Some rationalisation of competing stations occurred but it was not fully resolved. Between 1902 and 1904, connections were built to allow LCDR trains through running on ex-SER lines, notably in the Bickley area where the two main lines crossed. The rationalisation of the lines in Thanet to create a line which ran through from Margate via Ramsgate to Minster did not take place until after the grouping. In 1936 the former tunnel to Ramsgate Harbour became part of the Tunnel Railway underground railway system linking Ramsgate beach to Hereson Road, near mainline station. In 1923, the LCDR and the South Eastern Railway (SER), the London, Brighton and South Coast Railway (LBSCR), and the London and South Western Railway (LSWR) were joined to form the Southern Railway.

The former SER works at Ashford took over locomotive building for the joint concern, but some building work at Longhedge continued for a few years. The London, Chatham and Dover Railway Tavern, in nearby Cabul Road is widely regarded as having the longest traditional pub name in Britain. Rolling stock Both the South Eastern and London, Chatham and Dover Railway companies' locomotives were painted black each with their own style of lining but, when taken over by the South Eastern and Chatham Railways Managing Committee (SE&CR), dark green was adopted with an elaborate lining scheme. After some trials with a hybrid colour scheme (SER maroon on the upper parts and LC&DR teak on the lower), the SE&CR adopted the dark maroon/lake livery for passenger stock. Ex-LC&DR locomotives were renumbered by adding 459 to the running numbers (i.e. locomotive No 1 became No 460, etc.); SER locomotives retained their existing numbers. For a small and indigent company the
