Reference is made in the GTR brief in post 202
http://www.railforums.co.uk/showpost.php?p=2423098&postcount=202 that journeys from the stations south of Coulsdon South can only be capped at the daily caps in force from those stations and not some combination of the journey travelled outside London and one of the all-day caps inside.
On Wednesday, I made the following journeys using a contactless card
Train Redhill to Waterloo - touch in at 0609 (£5.80)
Two bus journeys (£1.50 x 2)
Train Waterloo to East Croydon - touch in at 2104 (£3.20)
Two bus journeys (the first charged at £1.40 and the second free)
The overall charge was £13.40. I thought at first this was the 1-5 cap and a single from Redhill to East Croydon but that doesn't add to this amount.
What was charged? And why does this differ from the staff brief which says that the only caps that apply from Redhill are £19 off-peak / £30.50 peak? Is this different for Oyster and Contactless?
