Train passengers travelling on the Norwich-to-London line will be able to print their own tickets or download them through a new pilot scheme.
Travellers will be able to book and pay for their tickets online and then print them at home or have them sent to their phone through operator Greater Anglia's app.
The pilot is in operation on the mainline, connecting stations from Sheringham and Cromer, and from Great Yarmouth to London.
From the autumn, the project will extend to other connecting stations and other routes where advance tickets are available such as a Lowestoft to London, and some mainline intermediate journeys. By January next year, all remaining routes will be covered.
The operator says the innovation will mean less queuing for passengers and, at rural stations without a ticket machine, the ability to buy advance tickets closer to the time of travel as they do not need to be delivered.
Andrew Goodrum, Greater Anglia's customer service director, said the changes would make the ticket-buying process 'simpler, easier and faster' for customers.
