A train ticketing trial which involves passengers’ journeys being registered by tracking their phones has been launchedA train ticketing trial which involves passengers paying for travel by having their phones tracked has been launched. Rail minister Lord Hendy said the initiative in northern England will make rail travel “simpler and easier”. From Monday, passengers travelling on Northern train services between Harrogate and Leeds will be able to pay for their journeys by boarding a train and pressing a button in an app on their phone. A barcode will be produced by the app which can be scanned by ticket inspectors and at station barriers. The scheme will be rolled out to services journeys between Sheffield and Doncaster, and Sheffield and Barnsley, in the coming weeks.
