Scenario:
- 1 unloading station, activated on demand when resources are low
- several loading stations, where loaded trains wait until the unloading station is activated.

Question:
- How does the game engine decide which waiting train goes to a activated train station?

Afaik, based on a dev reply somewhere if I'm not misremembering it, train ID number. Lowest first.

That said, in 2.0, station priority will influence this.
