Just a pre emptive one here...
Tonight I aimed for the 2020 Waterloo (WAT) to Basingstoke (BSK).
When I arrived at WAT concourse about 2015 the screens said the next fastest train to BSK was the 2105. There was no sign of the 2020 on its platform, just "delayed" and even RTT had no indication of when it might leave. I even looked at incoming trains onto the departure platform to see if I could get an idea of it would leave, but nothing was at the platform it was due at.
So, not wanting to stand around on the Waterloo concourse for ages and risk further delays, I jumped on the on-time 2020 to Woking (WOK), planning to get the 2119 to BSK, arriving at 2158 (although it did get there at 2155). If I had waited for the 2105 it would have arrived at BSK at 2147 which, though earlier, my decision meant I had less time standing around and I could get on with stuff, (and in any case the delay repay is the same, so it shouldn't matter to SWR).
However out of interest en route I checked the 2020 and it turns out that it departed at 2036 (the inbound train getting into WAT after I left), and it overtook me and got to BSK at 2122, 16 minutes late, and most annoyingly I would have got home an hour earlier as I would have got the hourly bus I needed. But I didn't get it due to the information at Waterloo.
I'm submitting a claim for 30+ mins, but will they argue that I should have stayed for 2105 and then noticed the 2020 was departing earlier? (It's only £3 compensation difference I think between 15 and 30 mins, but I'm really cheesed off as I'm now home an hour later because of it, though I know buses aren't the railway's problem, but it's really messed up my evening, so I don't want to give them slack on this)
