Good Morning,
I'm having a day trip to London on Tuesday 1st October and have bought an off peak day return from Freshford (from the forum service!).
The route is only valid via Warminster/Salisbury.
The return itinerary is to depart at 1823 from Waterloo changing at Salisbury.
The ticket has restriction US, I've had a look at this restriction but don't fully understand it. Can I get earlier/later trains?
Below is the restriction as described.
Thanks for any help.
