Hi, I am planning to travel from London Euston to Fort William on (the night of) Thursday 29th of May, and return on Sunday 1st of June.

I have a Caledonian sleeper reservation for the outbound direct journey, but the return sleeper from Fort William was sold out, so I instead have a reservation for the return from Glasgow to Euston. Both of these are sleeper supplements so I need to buy an underlying NR ticket. I had assumed that an off-peak return from London to Fort William would be fine for both sleeper services and also cover the in-between return portion from Fort William to Glasgow on the normal Scotrail train, but I'm not sure how to verify that for certain.

It's a bit tricky to actually purchase the NR ticket through online booking engines. As the sleeper services I'm taking (already have reservations for) are now sold out, I can't actually select my specific trains / routes. I am therefore trying to select journeys that 'look like' my journey on the same dates, and trying to decipher the T&Cs and restrictions. My specific concern is that if I select a non-sleeper return on the Sunday (Fort William-Glasgow-Edinburgh-Kings Cross) then off-peak return tickets appear. However, if I choose a return journey that uses the sleeper (Fort William-Glasgow-Edinburgh-Euston is the only one that comes up), only anytime tickets appear. I don't understand why return routes using the sleeper seem to be blocking off-peak return tickets from being offered.

The off-peak ticket, when I can get it to be offered, is an off-peak return from London Terminals to Fort William and says: "Any permitted route", "Return any day within 1 month", "Restriction code 5F". The linked page from Restriction code 5F says: "Valid on all Caledonian Sleeper services (with supplement)", "Break of journey is not permitted on the Outward journey".

So I think my question boils down to: given those ticket conditions, is my return journey plan (1st June Scotrail from Fort William to Glasgow Queen St, then same evening sleeper from Glasgow Central to Euston) okay?

I don't know about checking validity, but for this case the MixingDeck booking engine, which allows you to select the specific fare you want, may be suitable. It's available at tickets.gwr.com

Alternatively, you could try to buy the ticket you want from a non-journey planner TVM or from a booking office.

In the event of any difficulties just purchase a return ticket to Fort William from one of the London Northwestern branded ticket machines ont he day of departure.
