I’m Vice-Chair of Darent Valley Community Rail Partnership, and Southeastern has told us that Contactless will be extended to stations on the lines to Sevenoaks on 22 September, as part of Project OVAL. The readers and associated equipment have been installed and running for over a year now (fyi they incorporate Cisco hardware among other things). Stations covered are Eynsford, Shoreham (Kent), Otford, Bat & Ball, Sevenoaks and Dunton Green. This forum looks like a good place to post information about this route and others as contactless is implemented. The implementation is long delayed, so we don’t know if it will happen on the 22nd.
