What did I do?
Screenshots below show a simplified version.
Chainsignal working as normal:
Chainsignal turns blue when a station is plopped in betweem:
What did I expect to happen?
If all signals leading away are red, the chain signal should be red.
What happened?
Chain signal will never go red if the station is inbetween it and the red exit signals.
Reason for making this: I've got a number of same-named unload stations gated so that a train may only arrive at them when the station has enough room for a cargo. I do this by setting the signal entering that particular station to red and disabling the station. I have a stacker in front of the station to buffer some trains if needed (they are coming from remote mines). To prevent trains coming from the stacker to skip the unloading station entirely I need them to first pass an entry waypoint. The chain signal is meant to deny access from the stacker to this station until there is an unloading station ready to receive the train. I'll have to work around this with some combinators for the moment.
