Hello. I'm new to the forum, but I have been browsing for a while and have learned lots of interesting things. One of the subjects I've been trying to wrap my head around is permitted routes.
I came across a few mentions of a Box Hill-Betchworth season ticket which I found interesting. I've been doing some research on the Routeing Guide, but I'd like you to help me clarfiy a few things if you could.
In principle I pretty much understand why a permitted route would be via Epsom-Norwood Junction-East Croydon-Redhill although the logical (much shorter) way to travel would be to change stations at Dorking. Is the long route allowed because Deepdene isn't accessible? Or is it simply because there isn't a train that physically runs between the two Dorking stations? Are the two stations treated as an interchange station for the purpose of routing or separately as if they could be miles apart with no rail connection?
If one does take the long way around would the ticket allow one to exit/enter the barriers at any of the intermediate stations along the route? I presume the ticket works at the Dorking barriers since this would be the logical transfer point.
What really confused me was when I referred to the "yellow pages" for permitted routes between those stations. Box Hill is in the Leatherhead and Dorking Group. Betchworth is in the Dorking and Redhill Groups. Is it correct to conclude that the reason why the short route (changing stations at Dorking) is permitted is because those stations are both in the same group and the reason why the long route is allowed is because it's permitted between Leatherhead and Redhill? If so, then I get it.
However, what I don't understand are the other permitted routes between Leatherhead (Box Hill) and Redhill (Betchworth). There are four permitted routes:
AR: via Dorking-walk-Deepdene. The obvious route.
XE: via Leatherhead-Epsom-Norwood Junction-East Croydon-Redhill. I can see why that would be permitted especially on accessibility grounds.
The next two I don't completely understand.
HR+LB: These intersect at Mitcham Junction. I presume one is meant to change at Balham to head back down to East Croydon as above. This seems to be out of the way, but I suppose it's the alternative for trains going via Hackbridge from Epsom rather than West Croydon. Is that the rationale?
DK+LB: These intersect at Clapham Junction. Does this actually mean it is permitted to go via Epsom-Wimbledon-Clapham Junction-East Croydon-Redhill? If so, I would like that explained. Is it because two companies serve Box Hill and both need to have permitted routes?
Do these alternatives mean that the ticket would be accepted at all station barriers along all these routes? For instance could one exit at Balham to use the Tube or Wimbledon to watch some tennis?
To add to the confusion when planning the route on NRE via Leatherhead it gives me an option to go via Guildford (for the same fare as the short route via the Dorkings) which using the routing maps available above would either be HR+AR or DK+AR, neither of which are listed as permitted routes on the yellow pages.
I'd really appreciate it if any of you could answer my questions and clarify this for me. I was intrigued by this example, but presumably there are other tickets that permit unexpected routes. Thanks very much.
