I caught Tramlink from Wimbledon to Wellesley Road yesterday - I have a
monthly discount bus pass on Oyster which covers me for this. I touched
in my Oyster on the gates at Wimbledon and out again on the reader at
Wellesley Road. However I was surpised to see today that I'd been
charged a PrePay fare for this.

Luckily the Oystercard helpline people refunded the fare when I rang
them - turns out you have to touch in on the gates *and* on the platform
reader at Wimbledon. To me this is counter-intuitive, and I couldn't see
any indication that I had to do this at the gates at Wimbledon, or on
the posters on the tram or platforms (though I did find something on the
Oyster website later). I guess that it's because the gates can't tell
whether you are going to use the District line or Tramlink, but still...
What does anyone else think?

What's also strange is the amount it deducted - GBP1.10. The Tramlink
PrePay should be GBP0.80 single. The only guess I can make is that this
is the single or two-zone Tube PrePay fare, but I touched out at
Wellesley Road which you can't get to with Tube PrePay, and it's 3 zones
between Wimbledon and there. All very strange!
