One more question re capping. The very detailed Chiltern website (https://www.chilternrailways.co.uk/paygexpansion) says:” Any pay as you go with contactless journeys made between 16:00 and 19:00 will still count towards an off-peak cap.”
So if I travel to London after 9:30 and come back between 16:00 and 19:00, my evening peak contactless fare is added to my earlier fares, but I only pay up to the Off Peak cap? But if so, what is the point of the Peak Cap?
So perhaps this is a mitigation of the problem caused by the introduction of the evening peak fares on National Rail where there were none before (all depending on the capping level)?
Again it would help if you could explain this in your info pages.
