Signals make it possible to influence the behavior of trains running over tracks.

Platform train stop point

This is a hint for the train AI to stop at the signal position when stopping in a station platform.

One way

This is a hard rule for the train path finder to only run over the track in the signal direction. Trains will never consider tracing a path in the opposite direction.

No way

Trains will never trace a path crossing over this signal, from either direction.

Path signal

When a train arrives at this signal, it will consider the remaining path to its destination, up to the next same-facing path signal or block balise. If the path is clear of other trains or track reservations, it will proceed. If it's not, it will stop at the signal and check again in the future until it becomes clear. After the train proceeds past the signal it reserves the whole path of track segments for itself, until the next same-facing path signal or block balise.

Block balise

Block balises stop a train path check or path reservation from going beyond their point in the track, from both directions.

Block signal (Removed from the game)

When a train arrives at this signal, it will check if the block is clear of other trains, if it is, it will proceed. If it's not, it will stop at the signal and check again in the future until it becomes clear. After the train proceeds past the signal it reserves the whole block of track for itself, until the next block signal or block balise. As of now it is removed from the game
