I’ve just been through Abbey Wood and noticed that there are 6 new validators on platforms 3 and 4. They’re all covered with a dark blue canvas cover at present, but presumably they will be activated soon. Staff on the platform say that it’s due to happen by the end of the summer, so I think they’ve missed that.
Starting from the London end of the platforms, there is one at the bottom of the staircase from the small bridge. Walking towards the ticket hall the next two are at the bottom of the escalators from the middle bridge. Another two are at the bottom of the stairs the other side of the middle bridge, while the last one is at the bottom of the stairs from the tickt hall.
These validators are for the benefit of passengers travelling to/from Kent (beyond Dartford) using tickets instead of PAYG. They are able to touch in/out without having to go through the barriers in the ticket hall. I hope that they will be set to continuation exit in case PAYG users touch them in the middle of the journey. I also expect revenue officers to ask people touching them to show their tickets to Abbey Wood, especially at busy times, to catch fare dodgers from open stations like Slade Green.
