On Saturday I entered Wimbledon station through the gateline with £7.20 on
my Oyster card. When I touched in at the tram platform it said my balance
was £27.10 indicating an auto top-up had been applied somewhere (I was being
capped so there was only a 10p charge for the tram). Today my auto top-up
confirmation e-mail arrived quoting 'Wimbledon Tramstop' as the place where
the auto top-up was applied. I can only think that when I passed through
the gateline I had potential £4 fare deducted from the card and that when I
touched in on the tram platform the auto top-up was applied first (as is
usually the case) and then the correction was made. So I guess that is
another quirk of Wimbledon station.

I thought I'd see what my online journey history says. The account summary
says my balance is £27.10. The journey history shows my balance being
£15.30 on 17th March, has no record of all my journeys on 4th April (and
possibly some before that) and has no record of a bus, two trams, two tubes,
capping and an auto top-up on Saturday. It then shows my last journey on a
367 bus costing £1, being upcapped and taking my balance to £14.30 instead
of costing nothing, being capped and taking the balance to £27.10. I've had
individual trips and whole days of travelling not appear on my journey
history before, and the missing data might yet appear, but the details of
the journeys that do appear have always reflected the actual cost, the
capping and the resulting balance. Weird and useless.
