Some journey planners are already showing new fares for enquiries for journeys on or after 3rd December, suggesting the six week lead time has been met from the TOC side.
Interestingly, Shepperton to Fulwell appears to see changes in paper fare prices, consistent with the basis of single leg pricing for an enquiry (GWR booking engine) on 6 December, which would represent a fare hike for returns on Sundays and in the evening, although other times would see a reduction.
The current fares are
Evening / Sunday Single £4.00
Anytime Day Single £4.30
Evening Out / Sunday out £5.00
Off peak day return £7.00
Anytime day return £8.60
The new single fares are £3 off peak / £4.30 off peak.
Off-peak day return reduces to £6.00 but picks up the afternoon restriction.
Interesting to see a fare change implemented for the 'paper' structure, at the same time as the contactless extension happens, rather than both co-existing.
Appears that SWR abolish Sunday Out and Evening Out wholly within the CPAY area from 3 December, together with the introduction of afternoon restrictions on off-peak day returns with the peak flow.
For me (indeed, for almost everyone) that'll mean better off using contactless into London but a paper (or e-)ticket back out!
Not sure about that, if the off-peak single with the flow picks up an evening restriction out of Euston.
Bletchley to Euston might be a good case study for analysing the apparent stealth fare increases happening from 3 December, although some passengers will pay less. Bletchley to Slough might be even more stark.
