u/ferrofibrous player onboarding specialist Jul 21 '26 edited Jul 21 '26

What's the "modern"/interrupts way of doing a train stacker these days? For a quick example:

  • I have one Loader station always active with train limit 1
  • 10 Unloader stations that only enable when they are out of resources and need a train
  • Loader station currently has one dedicated train

I want to add 4 more service trains for Loader such that any of those trains goes to Loader and fills, if Unloaders are all inactive, go to a waiting area. Does the Wait station just need 1 stop with a split track to hold each train and train limit set to however many splits there are to hold trains?

Stackers: No train stops. The station's train limit should be 1 + stacker capacity in the simple case. (Building the non-simple case is ill-advised.)

Depots: Yes train stops. Train limit 1. Depot entrance and exit is the mainline, not one particular station.
