Windsor stations permitted routes query.

[bnm]

Walk up fares from Didcot to Windsor & Eton Central are cheaper than those to W&E Riverside. Can I use a CDR from DID to WNC to/from either station? I'm meeting a friend in Windsor then going back to his place in Bracknell, before returning home, same day to Didcot (actually Bristol, but DID is my usual split point for day returns to Thames Valley stations). Travel will be on a Saturday so no worries about peak/off peak.

Or will I need to excess my return portion to travel from Riverside?

The Routeing Guide shows both Windsor stations have the same routeing points - Slough and Staines, but I'm not sure whether the fares rule comes into play.

Help!

WCan I use a CDR from DID to WNC to/from either station?

I don't think so. The only time you have a choice is when there are a group of stations. It's got nothing to do with having common routeing points.

The only other way you can have a choice is that the station you want is an intermediate station on a permitted route and your ticket allows break of journey, but I would imagine the shortest route to WNC is via Slough, and not via Bracknell, so that doesn't work either.

And you must travel via Slough, as Staines fails the farecheck rule.

I think you'll need to excess.

As you say, the routeing points for both Windsor stations are Slough and Staines. Therefore, to determine which routeing point is appropriate, we need to perform the fre check.

Didcot Parkway-Windsor & E Ctl
CDS £12.90
SDS £13.90

Didcot Parkway-Windsor & E Riv
CDS £16.20
SDS £17.10

Didcot Parkway-Slough
CDS £11.90
SDS £13.90
For both Windsor stations, the Slough fare is cheaper than the Windsor fare for both second class single ticket types. Hence Slough is an appropriate routeing point for both Windsor stations.

Didcot Parkway-Staines
CDS £15.20
SDS £15.20
For both ticket types, Staines is cheaper than Riverside, but more expensive than Central. Therefore, Staines is an appropriate routeing point for Riverside but not for Central.

Routeing permissions for Didcot-Slough are BL and WR.

Both of these only give Didcot-Reading-Slough, so this is the only route on which the Windsor & E Ctl ticket would be valid. The Riverside ticket would also be valid via this route.

Didcot-Staines has routeing permissions London and CS+WX. However, all Didcot-Windsor & E Riv tickets are route Reading not Lond, so the London routeing permission is disallowed.
This gives:
Didcot-Reading-Wokingham-Ascot-Staines
Didcot-Reading-Slough-Hayes & Harlington-Kensington Olympia-Clapham Jn-Barnes-(via either Richmond & Twickenham or the Hounslow Loop)-Feltham-Staines.

As Windsor & E Ctl is on a valid route to Riverside, I would say that it would be appropriate to do an overdistance excess from a Central ticket to a Riverside ticket. For one leg, this should cost half the difference in price between the two tickets.

Thanks for that, clagmonster. I can just about get my head around permitted routes - but when the fares rules comes in to play my brain starts melting out my ears!
