On Saturday, I'm wanting to make a return journey from Cambridge (CBG) to Farnham (FNH), and travel via Guildford (GLD) on the return leg. Not being sure if this was a valid route, I tried it in National Rail Enquiries, and it seems to be valid, costing the same £39.20 (or £25.90 with Network Railcard) to travel via GLD that the "direct" route costs: http://ojp.nationalrail.co.uk/servi...021113/0700/dep/021113/1700/dep?via=Guildford
So far, so good, so I'll add the complex requiremnts in
. I want to break my journey on the return leg at both GLD, and in central London (somewhere around Piccaddilly Circus/Leicester Square/Covent Garden, still TBC). I assume that there are no problems with breaking at GLD, but as far as I can see, the cross-London part of the CBG-FNH ticket only allows me one tube journey in either direction and doesn't let me break the journey half-way across London. So this ticket doesn't appear to be valid for what I want to do.
Therefore, I investigated getting separate CBG-London (£10.55 with Network Railcard) and London-FNH tickets (£10.95), and using Oyster for the three tube journeys (one outward, two return with the break of journey), costing an additional (3*£2.10 = £6.30), so the overall cost has increased a bit to £27.80. This seems to have solved the problem, and is only slightly more expensive, so not really a problem.
Then I remembered Boundary Zone 6 tickets. I almost wish I hadn't, considering how confused I've now become! But it's too late now...
I checked CBG-London with a travelcard (£14.50), plus BZ6-FNH (£6.85, according to brfares.com since National Rail Enquiries doesn't do BZ6). Total cost now only £21.35 - which lets me do the break of journey in London, and is cheaper than the direct ticket I started out with
But would splitting tickets at BZ6 affect the validity of the routing via GLD? Since National Rail Enquiries doesn't do BZ6 I can't easily check the routing for this. So I picked a station just inside zone 6, Surbiton (SUR), and compared SUR-FNH with and without a via GLD option. National Rail Enquiries shows that travelling via GLD now requires a much more expensive ticket: http://ojp.nationalrail.co.uk/service/timesandfares/SUR/FNH/021113/1000/dep/021113/1700/dep (£6.85 return if travelling direct - same cost as the BZ6 ticket) compared to http://ojp.nationalrail.co.uk/servi...021113/1000/dep/021113/1700/dep?via=Guildford (three separate singles adding up to £14.90 if travelling via GLD). This suggests to me that it might not be valid to do the route via GLD on a BZ6 ticket. But is SUR-FNH is the right thing to be checking for the BZ6 ticket?
I know that with a travelcard+BZ6 ticket combination, I'm treated as if I'm doing one journey from London to my destination, and the train doesn't have to stop at a BZ6 station, unlike with normal split tickets. So might it be more reasonable to check the valid routes of Waterloo-FNH, instead of SUR-FNH? National Rail Enquiries tells me that the journey from Waterloo is the same price with and without the via GLD routing, suggesting that the via GLD is now a valid route.
So ... which routing does actually apply to the travelcard+BZ6 option? Can I travel via GLD on this ticket combination, or not? (And if I can, does anybody have any thoughts on how likely it is to be hassle-free?)
