There are two railway South London Lines, both operated by South Central Trains - the "inner" and "outer" lines, both running from London Victoria to London Bridge.
The "inner" line has the following stations:
- London Victoria
- Battersea Park
- Clapham High St
- Denmark Hill
- Peckham Rye
- Queen's Road Peckham
- South Bermondsey
- London Bridge
The "outer" line describes a greater area, following the Brighton mainline for a while. It has the following stations:
- London Victoria
- Battersea Park
- Clapham Junction
- Wandsworth Common
- Balham
- Streatham Hill
- West Norwood
- Gipsy Hill
- Crystal Palace
- Sydenham
- Forest Hill
- Honor Oak Park
- Brockley
- New Cross Gate
- London Bridge
The "inner" line will soon form part of the East London Line eminating from Surrey Quays after it has been extended, and the eastern portion of the "outer" will too, as part of the line from New Cross Gate extending to Crystal Palace.
