Bromley North Station
Zone 4 rail station in South London, terminus of a short spur off the South Eastern Main Line at Grove Park. The only service to this station is a shuttle service from Grove Park via Sundridge Park, and there's no service at all on Sundays.
Bromley South Station has many more services, and is about a kilometre's walk away (just over half a mile).
Comment added by Anonymous: Though Bromley South is only a ten minute walk away, and runs more services, Bromley North provides services to the West End (Charing Cross) and key commuter destinations (Cannon Street, London Bridge and Waterloo) not served by the other station.
