History

Construction

The North Kent Line was the means by which the South Eastern Railway (SER) was able to connect its system to London at London Bridge. In 1846 the SER purchased the Thames and Medway Canal tunnel near Higham and laid railway tracks through it; in 1847 trains were working through from the Strood terminus, on the River Medway to Gravesend. From 30 July 1849 the line was extended, via Blackheath, to a junction with the London and Greenwich Railway at North Kent East Junction, near Deptford, and through trains were now able to operate.

Electrification

The line is electrified (750 V DC third rail). Electrification was initially to Dartford (6 June 1926) and was extended to Gillingham by World War Two.

Former services

Between 1999 and 2002, there were semi-fast trains running from Plumstead to London Victoria briefly resuming a 1980s service pattern. This service was for the Millennium Dome; the service called at, Woolwich Arsenal, Charlton, Blackheath, Lewisham, Peckham Rye then non-stop to London Victoria. There was also an early morning semi-fast service to London Blackfriars from Dartford in the 1980s.

In 2003, there were plans to run a Plumstead to Clapham Junction service across South London, but it never came to fruition.

Route

The line diverges from the Southeastern Main Line at Lewisham Vale junction[3][4] at the country end of St John's station at the edge of Inner London, and runs as far as Rochester Bridge junction[5][6] beside the River Medway by the north coast of historic mid-Kent.
