Aargh
I looked up the journey from Salisbury to Cardiff on 20th September. Sure enough, it gave five options routed via Swindon outward, and (for the time of day I requested) four return via Swindon.
So far so good....
BUT...according to
www.nationalrail.co.uk ...
No return fares available
In spite of it being the same route for all 5 outward trains, four different Super off peak fares were quoted:-
^39.75, ^42.55, ^44.75, ^44.75, ^37.00 on the 10:30, 12:28,13:28,14:28 and 15:28 respectively;
The four journeys back via Swindon were quoted at ^21 for all of them (unspecified type of single)
ALL the above were tagged with "Multiple tickets required"
THEN to cap it all, there was a final journey back quoted:-
Cardiff (20:15) to Bristol
TM‡ (21:04)
Bristol (21:44) to Exeter SD (22:44)
Exeter (23:10) to Honiton (23:29)
Honiton (23:35) to Salisbury (02:08) by bus
And the fare for this marathon? ^25.50 anytime return - the only journey quoted with a through ticket
PS. I have just discovered that the variation in the outward prices is beacause, although the fare comes up as "Super off peak", it is in fact a combination of a
SOP▸ Sal-Swi plus an advance purchase Swi-Cdf - this becomes apparent as one moves towards the ticket purchase stage, although it refers to ticket 1 of 2 and 2 of 2, but lists 3 tickets
