CHILTERN Railways is more than doubling the availability of mobile phone tickets across its route.

The daily quota of tickets has been increased from 490 to 1,010, with new ticketing options from Birmingham, Banbury and Bicester North.

Passengers receive their ticket as a barcode sent directly to their mobile phone by a text message, which rail staff can check with special barcode scanners.

Chiltern's commercial director Neil Micklethwaite said: "We continue to be delighted with the popularity of mobile ticketing, both among staff and passengers."
