There is an interrupt condition "Destination full or no path"
There are also similar sounding wait conditions "Station is (not) full"
Unfortunately the wait conditions don't emulate the interrupt condition

Consider a situation when you have disjoint rail networks, with same name stations
Within first rail network suppose the station is full, and in the second it is not full
If a train in first rail network has the interrupt condition, it would trigger
But waiting on condition "Station is not full" would immediately pass, because the station in the separate rail network fulfills it

Hilariously though waiting on "Station is not full" is not even necessary, functionally this situation works, as the train is stuck in a perpetual interrupt loop
But despite this working, it is annoying because it is constantly alerting "train has no path" , and disabling that alert is not ideal

One could consider this to be a feature request for a "there is a path to station" wait condition
Though I'm not sure when would you want the current "station is not full" and wouldn't want a "there is a path to station"

Just for completeness, in my setup I have 3 kinds of station, IMPORT, EXPORT, and PARKING
All trains have schedule:
goto EXPORT until cargo full
goto IMPORT until cargo empty
With an interrupt:
If no path, goto PARKING

I would love to be able to add a condition to the interrupt:
(cargo is empty AND path to EXPORT exists) OR (cargo is full AND path to IMPORT exists)

I posted this to Bug Reports, no idea why it ended in Gameplay Help
