Rail passengers on two routes in Yorkshire have made more than 30,000 journeys using a ticketless system as part of a trial, operator Northern has said.
The system became available on the route between Leeds and Harrogate in September and was extended to trains between Sheffield and Doncaster in November.
A smartphone app uses GPS to track journeys and charge users the best fare on the day, Northern said.
Commercial and customer director Alex Hornby said the technology represented “the future of ticketing”.
“We’ve been receiving a lot of promising feedback so far, with high app review scores and many saying it makes travelling by train easier and more straightforward.”
He said more than 3,200 passengers had used the app on the two routes in Yorkshire.
The technology is also being tested on some trains in the East Midlands, but a planned trial for services between Sheffield and Barnsley was postponed.
