The station is the nodal point for three lines from London: * the North Kent Line, via Woolwich Arsenal * the Bexleyheath Line, * the Dartford Loop Line via Sidcup. Lines terminate west of Dartford at London Charing Cross and London Cannon Street via London Bridge, and London Victoria. Dartford station is outside the Travelcard zones and Oyster card network, so travel by these tickets are not valid at this station, although the London Boroughs' Freedom Pass is valid. British Transport Police maintain a neighbourhood policing presence at Dartford.
