I had a peep today on Platform 1 seeing as I'm now commuting by train thanks to the 176 getting held up for 20 mins at a time in Waterloo. I take it the concrete holes is where the lift shaft is?
Incidentally, I tried to use the self-service machine at 9.15 by the cashpoint and for some reason it decided to re-boot itself! So went to the other one which always has someone fiddling around for change and managed to buy a ticket. The queue for the ticket office was by the door!
