The North Kent Line^[1][2] is a railway line which branches off the South East Main Line at St Johns junction west of Lewisham station in Greater London and runs to Rochester Bridge Junction near Strood, Medway where it links to the Chatham Main Line.

The section from Charlton to Dartford is also referred to as the "Woolwich Line" in the context of Southeastern Metro services.

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.

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.

From 1999 until 2002, there were semi-fast trains running from Plumstead to London Victoria, temporarily resuming a 1980s service pattern. This service was for the Millennium Dome; trains called at Woolwich Arsenal, Charlton, Blackheath, Lewisham, Peckham Rye, then ran 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 which had never came to fruition.

Until May 2018, there were regular semi-fast services to Gillingham (Kent) from London Charing Cross via Lewisham (for DLR) and Woolwich Arsenal (for DLR) operated by Southeastern calling at Waterloo East, London Bridge then non-stop to Lewisham (for DLR), Blackheath, Charlton, Woolwich Arsenal (for DLR), Abbey Wood (for Elizabeth line), Dartford, Greenhithe (for Bluewater), Gravesend and then all stations to Gillingham (Kent). Since then, these services were replaced by the new Thameslink services from Luton calling at all but some stations to Rainham (Kent).
