Category: Dartford Loop Line
Rail line connecting London with Kent. Not sure why it's called the Dartford Loop Line, since it's not actually a loop. Trains from central London (Charing Cross or Cannon Street) follow the South Eastern Main Line down as far as Hither Green; at this point the Dartford Loop Line departs from the main line to head east.
Stations on the line from west to east (view them on a map):
