Steam had S&C on sale, so I bought the route.
Not editable, rats.
Had the route in TS12 61388 and thought about what happens if I brought the old route into TANE.
Rats, DRM'd in 61388, so fired up 49922 and put S&C there. Wow, no DRM.
Made a new KUID version of Skipton and imported that into TANE.
Only some trees and three track components missing, CDP'd them from 49922. Everything works with all the new assets.
Switched the first session to the new route KUID, works so far.
With Andi06's Protrack:

All the routes work!
Hope that helps someone.
