After lurking here for so long, I think I'm getting the hang of Routeing now.
One thing I've never seen stated explicitly, though it is implied by the routeing solutions people offer, is whether the maps give all the information necessary to check that a proposed permitted route does not involve doubling back ?
- I ask because the rule about doubling back seems to apply to any station, but the routeing guide only shows routeing point stations (and groups).
I guess :? this is covered (at least in part) by the fact that many of the stations not shown on the maps are those within routeing groups. (Stations in a group are always OK for doubling back through 'for interchange purposes'.)
But is it definite that there are no other 'invisible' stations that can cause a doubleback 'trap' unless you also look at the full network map?
