Those are pretty much the questions I was asking earlier, on various threads.
Inwards from West Drayton, where contactless and
Oyster▸ were already in use, the
GWR▸ paper tickets have the same role as
TfL» paper tickets - a painfully expensive backup for those without cards, and an inducement to use them. But here it's a bit different, as without Oyster there is still a need for paper tickets, and the prices "match" - sort of.
I see what you mean about that GWR page of information being vague. It talks about accepting contactless, without separating the two different meanings of that - accepting at a station, by providing tap-in barriers, and accepting on trains as a valid ticket.
The official rules for using contactless might be found in the restriction code for it; and it does have one (PQ, for off-peak). However, it isn't a real code as it's not a real ticket in all respects. And the
NRE‡ journey planner doesn't recognise it, and offer it as a fare. From West Drayton inwards, a little message appears in the
OJP▸ saying what the contactless/Oyster cost would be "from" (i.e. off-peak). The words there, and on the page it links to, don't saying anything about specific journeys or trains, though. And from Reading, even that isn't shown.
What does code PQ say, for what it's worth? The ticket code is POC CPAY OFFPK INFO; I assume INFO means for information only, not defining a proper ticket. The words mention Oyster, and capping, since the code applies to all contactless journeys. It defines the time validity as
"Not valid to depart any location 0630–0930 on any
TOC▸ "
- but of course it works off tap-in time, not departure time. Anytime tickets don't have restriction codes, but peak contactless (PAC CPAY PEAK INFO) does: code PI. It has this limitation:
"Not valid to depart any location 0931–2359 on any TOC".
And, to make the point that it's not a proper ticket, in the validity section (i.e. what future days) it says "NOT FOR TRAVEL (1 day)".
The text version is more sensible, and it is available at
www.nationalrail.co.uk/pq (and /pi):
Restricted Days: All days
Outward Travel
Validity based on the time of touch in on the Oyster card validator at the origin station of the journey:
Mondays-Fridays not valid between 06:30-09:30 (also not valid between 16:00-19:00 if journey ends beyond Zone 1).
Valid all day Saturdays, Sundays and Bank Holidays.
Contactless Payment Card or Oyster card with pay as you go credit required. Not to be issued as traditional “paper” ticket.
Charges capped at daily price cap limit, based on all journeys made on the card between 04:30 and 04:29 the following day
Return Travel
Not applicable.
But we knew all that anyway, for
PAYG▸ as a whole. How this is all supposed to work out to Reading is still a bit of a puzzle, especially given the very different system of peak/off-peak acceptance on GWR trains in the evening.
