Raynes Park has a road going under the end of the up platform (the platforms are staggered). This bridge replaces the original road bridge, now a pedestrian tunnel, which also goes under this platform. This is the second replacement bridge, the first, now a bike tunnel, goes under the very end of the up platform. The first bridge was a typical LSWR under-bridge, just about big enough for a horse and cart; I think that the first replacement could safely take a single-deck bus and the current one a double-deck bus, but I'm not absolutely sure.
The up platform at Kingston has recently been extended over the Richmond Road.
