It is 44 miles 42 chains (71.7 km) from London Bridge via Redhill.
Plumpton lies on the London, Brighton and South Coast Railway "cut-off" line between Keymer Junction, near Wivelsfield on the Brighton Main Line, and Lewes.
The erstwhile Brighton, Lewes and Hastings Railway were authorised to build the line in 1845; the LBSCR purchased it and opened the link on 1 October 1847.
However, Lewes District Council rejected the plans to replace the gates as it would have caused "substantial harm to the significance of the signal box",[4] and there were protests from villagers.
