That leaflet (more of a card, really) directs you to tfl.gov.uk/modes/tfl-rail, but you need to poke about somewhat to find the relevant extra details. One thing I found there is this page, which explains capping for trips in the Reading-Iver zoneless zone:
National Rail fares, caps and Travelcards beyond Zone 9.
You can use contactless (card or device) or an Oyster▸ card to pay as you go for travel to and from:
Broxbourne, Rye House, St. Margarets, Ware and Hertford East,
Gatwick Airport, Merstham, Redhill, Earlswood, Salfords and Horley
Ockendon, Chafford Hundred, Purfleet and Grays
Epsom
Cuffley, Bayford and Hertford North
Radlett and Potters Bar
You can only use contactless (card or device) to pay as you go for travel to and from:
Brookmans Park, Welham Green, Hatfield and Welwyn Garden City
St Albans City, Harpenden and Luton Airport Parkway
Iver, Langley, Slough, Burnham, Taplow, Maidenhead, Twyford and Reading
Journeys to or from these stations aren't included in caps.
That says (I think) that the caps applying to the rest of the network still operate, but journeys into the elsewhere zone are not counted in them. However, there is something so like capping that everyone - except
TfL» - is going to call it that:
If you use contactless (card or device) to travel to or from Reading or Iver and you travel in Zones 1-6, we'll automatically refund the difference if a Day Travelcard was cheaper. Refunds may take up to 14 days.
Station | Anytime Day Travelcard | Off-peak Day Travelcard |
Iver | £21.00 | £14.00 |
Langley Berks | £23.50 | £14.90 |
Slough | £24.30 | £15.50 |
Burnham Bucks | £26.80 | £16.20 |
Taplow | £29.40 | £17.30 |
Maidenhead | £30.70 | £17.90 |
Twyford | £36.10 | £21.40 |
Reading | £55.90 | £26.00 |
Obviously that should read Reading to Iver inclusive.
Presumably it's not called capping because many of the things they say about capping don't apply to it. However, I think it will need a name of some kind, needed even to talk about that kind of distinction.
