Jan 2015, Neil Williams remarked:
For example: London-Exeter route Honiton is £71.60, and via Taunton £103.50
If I had a via Honiton ticket and wanted to return via Taunton could
I excess it for half the difference? Or would they want the full
£31.90
Similarly, in reverse, can I excess a "via Taunton" ticket to be
"via Honiton" for a negative amount [in practice I wouldn't expect a
cash refund, just the ability to travel for no extra charge].

Yes, half the difference, though finding a member of staff that knows
that and how to do it can be very challenging indeed. In the second
case you can technically get a zero fare excess

Thanks.

but in practice the more expensive ticket should just be accepted via
the cheaper route.

There must be a reason why the tickets are "via Taunton" & "via
Honiton", and not "Any permitted" & "via Honiton". A lack of faith in
ORCATS apportioning the revenue fairly, I guess.

What you can't do is have half a ticket with NSE discount and half not,
if I'm reading your thread on uk.r (this is on uk.t.l) correctly.

Yes, I posted in the wrong newsgroup.

I was pondering if this would be a better answer to the question "Is a
via Taunton ticket valid on a train to Paddington that's bypassing
Taunton because of engineering works, and going via Honiton".
