[0.15.x] Trains should ignore disabled stations

[Scf]

0.15.x added an ability to disable stations via circuit network, but it is of limited use - train will stop with 'no path' if next station in schedule is disabled.

For loading/unloading stations it makes much more sense to keep train there instead on previous station - it is just much faster.

My suggestion is: if next station on train schedule is disabled, skip it and move to station after that disabled station.

You need to make sure the station after the disabled one can be reached, if this is the case then this would be a bug, then post the save please.
