Whether you can or not depends on the type of ticket you've booked. Anytime, Off-Peak and Super Off-Peak tickets are more flexible options, so breaking your journey is allowed, as long as you don’t start your journey before, or end it after, the two destinations that are written on your ticket.
Checking the terms and conditions of the ticket you bought will provide more information.
We highlight calling points of all journeys so you know which stations the train stops at.
If you have an Advance ticket, breaking your journey’s not allowed, unless it’s to change to/from a connecting train, which will be written on your ticket.
