The funny bit is the shape of the island: where it has faces on both

the through line. Specifically, apparently exactly far enough back to
fit another track in between it and the existing track.

Any idea of there's a reason for this?

Belay that question - answer found after thirty seconds of searching.

Was there ever a third track there? With the present platform layout, it
would have to have been a bay platform, but one which would have
received trains from the Sutton direction, which seems unlikely.

But apparently true:

The track that is now Tramlink used to run from Wimbledon to such a
platform.
