I'm trying to work out what routes a Basingstoke to London Terminals Route Any Permitted season is valid by, with a particular interest in South London. I’m not expert at all with the routing guide, but here goes.
Basingstoke is a routing point, and all the London terminals referred to below are in the London Terminals group routing point.
The permitted maps are:-
LE - gives the direct route via Woking to London Terminals, the obvious terminal being Waterloo.
PZ - which gives the route via Reading to Paddington.
PZ+WX - which gives via Reading then Ascot - Hounslow/Richmond - Clapham Jct - London.
So far so good.
BU + WX
I think this allows Basingstoke - Weybridge - Virginia Water - London via the touch point at Weybridge, which seems OK. This would also allow changing at Woking for Virginia Water on the days when the service runs that way.
BU also gives Basingstoke - Wimbledon - Streatham then Nunhead, Herne Hill and Peckham Rye, but these three end points are not then directly linked to London Terminals. So this I think makes them irrelevant.
Looking at the WX map at the London end, the map just draws a line from Clapham Junction to the London terminals routing group, not to specific stations.
So I think it is accepted that this allows Clapham Junction to Victoria, and also to Waterloo, and by changing at Waterloo to Charing Cross, London Bridge, and by changing there again Cannon St and Blackfriars/City Thameslink.
However it would seem reasonable, given that no detail is given on the map between Clapham Junction and the London routing group, that you could change at Clapham Junction and travel via Denmark Hill to Blackfriars. A variation would also be Clapham Junction to London Bridge via Peckham Rye. National Rail supports the first, but with two tickets, and will allow the latter.
A further routing that would make sense would be changing at Wimbledon to go via Tooting direct to Blackfriars. If you start a journey at Wimbledon it is definitely a permitted route, as a direct service, but coming from a distance and changing it appears not to be using the journey planners.
In all these examples the mileages are slightly higher than going via Waterloo. Clapham Junction - Blackfriars via Denmark Hill is 7.5 miles, 6 miles via Waterloo/London Bridge so within the 3 mile tolerance. Clapham Junction to London Bridge via Peckham Rye is 8.25 miles, 5 miles via Waterloo. So outside the 3 mile tolerance but within the booking engine 5 mile tolerance. Wimbledon to Blackfriars via Tooting adds 4 miles.
As both origin and destination are routing points, fare check is irrelevant.
I cannot find any relevant easements or negative easements that apply to these journeys.
So my question is, are these routes valid with a season? They all appear not to be circuitous but are mildly longer by distance.
Basingstoke -> Clapham Junction -> Peckham Rye -> London Bridge
Basingstoke ->Clapham Junction -> Denmark Hill -> Blackfriars
Basingstoke -> Wimbledon ->Tooting -> Blackfriars
Finally given the lack of detail on the map between Clapham Junction and the London routing group, what prevents travel to Euston via Willesden Junction changing at Clapham Junction? This is a rail only route to that particular London terminal.
