Merstham and Couldson South.
The quarry line (Brighton Mainline Fasts) passes close by but there are no platforms.
Could argue Salfords too.
Aren't Reedham and Coulsdon Town the same place?

Always liked how they fit this station on the slow lines, it is always odd to see the platforms and distinctive ramps from the windows of a Virgin speeding past.Euxton Balshaw Lane.
Very interesting and good photos! I must have travelled out of Marylebone a fair few times in my life but never knew that. I've been having a look on Google Earth also and two other interesting things I've learned - (1) You can follow the path of the line south into Marylebone by looking at the curvature of the roads above the tunnel, (2) I had always thought that the Metropolitan Line tunnels were alongside the Great Central line but in fact they are up to 200 yards to the east, more or less all they way to Finchley Road station - and they are in a tunnel where they cross the WCML and (3) the Metropolitan line runs in the open air just behind a wall alongside the pavement of the Finchley road adjacent to where Marlborough Road station was situated.
Carstairs - the route used by trains avoiding the station (usually those travelling between Lockerbie and Edinburgh) is south of the platforms (but clearly visible)
Caldicot.
The Carried loop line passes over a fair way south of Catford Bridge.Catford Bridge has the Catford loop line pass over just to the country end of the platform. Similarly Penge East has the line from Penge West cross over to the London end. None are connected though not sure if they have 'out of station interchange' fare provision on Oyster?
