I’ve found what looks like a bit of an oddity in the fare table.
Idly looking at pricing to South Kensington from the SWR network I find that starting at Wimbledon has 3 options (which I rather expected):
Default (presumably district line direct although it would also cover WIM – CLJ – South Ken)
via Waterloo (etc.)
via Vauxhall (etc.)
However, if I start further out (e.g. Worcester Park or Epsom) I only see two fares:
via Vauxhall (etc.)
Default
The default fare must cover changing from NR to LU at Wimbledon or Waterloo which surprises me. It’s the premium price option and I would have expected the Wimbledon change to be at least as cheap as changing at Vauxhall if not cheaper.
To be fair, the fares from Epsom are identical on all routes while those from WCP only differ in the peak so maybe the potential differences are too small to worry about given the guarantee of a NR/LUL mix of modes but if that were the case then I don’t see why changing at Vauxhall etc. would be cheaper than Wimbledon.
Deliberate or accidental, I wonder?
