9. Trowbridge (again).

Indeed, Yes :-)
8. Peterborough?
No sorry

I'm going for 8 to be Retford thinking it's on the same line as you Rts
Yes - Retford. The 180 hasn't actually called there, it's waiting for an Eastcoast service to overtake

As the 24 hour rule has now exceeded, I'll have another punt and say that 4 is Didcot Parkway?
You're right, the 24 hour rule has passed

But you are wrong in thinking it is Didcot Parkway
