Balham PAYG Starting Soon

Hurrah! I guess it might be connected to Balham also being an Underground station, so Oyster being already valid for journey's from balham to victoria (albeit via embankment). The other thing is that Southern's WLL services (which already accepted oyster PAYG) also travel via Balham, so this is a convenient extension for users of that service as a first step.

Also hurrah for the pink blobs on the map there!
