The 16-17 Saver will go on sale on 20 August 2019. It's valid across England, Wales and services into Scotland, but not on ScotRail or Caledonian Sleeper services.
Holders of a 16-17 Saver will be able to buy discounted tickets for travel from 2 September 2019.
Customers will be offered the 16-17 Saver as either a digital product on their phone or a physical card that will be posted to them.
It's not possible to have both, this is in line with other discount products.
