Can any one advise on permitted routes for a Rishton to Cambridge.
Would going via Birmingam on the outward and Leeds on the return be permitted.
Can I just check as I don't think this will be permitted national rail is saying on the return changing at Peterborough and Leeds to catch the 21:08 from Leeds to Blackburn and then doubling back to Rishton.
No, doubling back is almost never allowed.
You're expected to change at Accrington going on that route, but I guess you will have missed the last local train by the time you arrive there at 22:22.
