With the introduction of TFL contactless fares from St Albans there is a large saving to be had now that Off Peak single fares are available for the first time on many routes. A Thameslink priced Anytime single from St Albans to Putney (via West Hampstead and London Overground and avoiding London) is £13.70, with no off peak option available. Using contactless off peak on exactly the same route (avoiding TFL Zone 1) now only costs £5.80.
The last leg of the journey can be made by changing at either Richmond or Clapham Junction depending on which London Overground service is taken from West Hampstead. The TFL fare finder page warns that you must travel via Clapham Junction and touch the pink validator there to get the lower not-via-Zone 1 fare. There is no mention of going via the validator at Richmond - which seems an entirely reasonable route. My question is: What would I be charged if I took the Richmond route?
