Train stop: Read stopped train bug

Post by Skeletpiece »

Consider this setup:
Train id = 755

If train arrives, rail signal turns green [Condition = TRUE] (For now its ok)

Steps to reproduce bug:
- Turn to manual mode (Don not move the train)
- Schedule the train to move to another Train Stop
-> Train will not move, although train is in the same stop, train id is not read

Temporary workaround:
- Send the train to the original station (For signal to put in green color)
- Now move to the other station

Tried to reproduce the bug, shifting between manual and automatic works normal. What do I miss?

Thanks for the reply disentius, you missed the "GO TO THE STATION" option in the train menu :roll:

Aha, you are right. Reproduced the event.

It seems to stem from the order of events sent.
-> Manual -> No train signal T sent (expected behavior)
-> Go to station -> (1)train starts moving (2) is set on automatic. The moment the train starts moving, the T signal stops being received and the signal stays red.

What do you use this setup for? (the signal after the station)

Keep in mind it's intentional that a station only yields circuit network signals if a train is stopped at it as part of its schedule -- once a train has advanced the schedule to go somewhere else, the station will stop giving signals.

That is a valid argunent, TruePikachu. Seems like it is intentional behavior then.

Correct. A train only gives data to a train stop it is actively stopped at as part of an automatic schedule. If it happens to physically stop in front of another stop it completely ignores it.
If you want to get ahold of me I'm almost always on Discord.
