Train station circuit condition based on another station state

[CzBuCHi]

TL;DR

Ability to hold train in station until next station on train shedule is enabled.

What ?

When having this type of shedule:

• Load stack

• Load

• Unoad stack

• Unoad

on which stations "Load" and "Unload" get disabled via circuit network. Train will loop between stack stations. Currently circuit network controlled signal is required to hold train in stacker.

Why ?

CN gets really complicated if stacker is shared ...and to not wastle fuel
