For the most part, most routes use most of the track that is in game with a few exceptions.... -Oakville has all that industrial trackage that isn't used. -Sherman Hill has track 3 from the summit to Cheyenne but it wasn't finished b4 the routes release. -AFAIK, no services use track 2 on Cajon pass from summit to the base of the pass, not sure why. Also the crossovers from the Palmdale cutoff to the BNSF line are not used either.....
Long route with A & B points at each end = two different runs, A --> B, B --> A Long route with A & C points at each end, plus a B point halfway = six different runs: A --> B, A --> C, B --> C, C --> A, C --> B, B --> A
how do you get A to C, when on a railway, it is always A to B, there can not be anything else like on Cajon Pass, it is San Bernardino (A) to summit (B), or Barstow (A) to Victoriaville (B), Hysteria (A) to San Bernardino (B), where can you have C
Wasnt held back - though I can see how it might look like that. I didn't build the main timetable, I fixed it up and then updated the F7 services and spread them around a bit. No idea why I didn't do the same on the other ones tbh - just stressed I think!
