Long-awaited plans for contactless "tap and go" payments across the c2c line have been delayed due to a cyber attack.

c2c, the south Essex rail operator, has announced that the launch of this system across its entire route has been postponed.

This is due to the ongoing cyber security incident at Transport for London (TfL).

The roll-out was initially scheduled to be in operation at all stations from September 22.

This cames as frustrated customers regularly complained about broken ticket machines as well as issues with smartcards and mobile apps.

Bosses were confident the new “tap and go” system will relieve many of the issues and will be ready to go after rigorous testing.

However, the operator confirmed that this has been put on hold following a statement from TfL earlier today.

Shashi Verma, TfL's Chief Technology Officer, said: "The security measures we are taking mean that it is now not possible for us to deliver the necessary system changes to enable 47 additional stations outside London - including 15 stations on the c2c network - to benefit from pay as you go with contactless on September 22 as planned.

"We are working with DfT and the Rail Delivery Group to reschedule and we apologise for the delay."

The rail company previously confirmed the pay as you go with contactless would be available during both peak and off-peak times to all customers.

Rob Mullen, managing director at c2c, added: “The serious nature of the ongoing Transport for London cyber attack means it is not possible to launch pay as you go with contactless across our route as planned on 22 September. “While this is extremely unfortunate, we recognise that it is vitally important that all issues are fully and satisfactorily resolved by TfL before we move forward.” “c2c is currently working closely with industry partners and colleagues at Transport for London, and we look forward to sharing a new launch date for pay as you go with contactless with our customers in due course. “We remain fully committed to this fast and flexible ticketing and payment method which will make travelling with c2c quicker and easier than ever before.”

TfL has assured that they are working to resolve the issue as quickly as possible.
