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

Signal menu

The signal menu is accessible in the track editor [F2] and has two different modes:

• Move, delete, edit signals [K]: This mode allows you to move, delete and edit signals. You can move them by selecting them and then just dragging them and delete them when pressing [delete]. Every signal type has an own menu to edit them, you can access it by by selecting the signal and looking at the let top side. There you can change the type of the signal, flip it or have additional settings. Pressing [F] while signals are selected will flip them.
• Create new Signals [L]: This mode allows to create new signals.

  The two signal menu modes

Signal types

• 

  One way signal

• 

  Platform train stop point

• 

  Block balise

• 

  Path signal (unbound)

• 

  No-way signal

One way [1]

This signal only allows trains to travel in the direction of the arrow. it will also block all paths of path signals that are against its own direction.

Platform train stop point [2]

If you place this signal, trains will stop at it, when you assign the platform via basic stop assignment mode.

Block balise [3]

Block balise menu

Block balises stop a train path check or path reservation from going beyond their point in the track, from both directions. There are additional options accessible, if you select the signal. The second one allows you to shift the balise to the side of the track, it is purely cosmetic. The third option lets you choose how the balise should work. The option already selected is the most frequently used option and behaves as described above. There is also a field where you can assign tags to the balise.
The two options and how they interact with tagged trains:
Applies to all trains: This is the default option. If you now assign tags to the balise, it will work normally for all trains that do not have this tag assigned, but it will not be seen as a balise by trains that do have the tags.
Ignored by all trains: If you select this option, the balise will be ignored by all trains without a selected tag, but will be seen as a normal balise by any train that has a selected tag.

Path signal [4]

Path signal menu

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.
Applies to all trains:
Ignored by all trains:

No-way [5]

No-way signal menu

This signal blocks trains from passing over it. There is a option to change the mode of the signals and a field to assign tags to the signal.
The two options and how they interact with tagged trains:
Applies to all trains:Without a assigned tag to the signal, any train will be blocked from passing it. If you assign a tag, all trains with that tag will be able to pass the signal.
Ignored by all trains:Without a assigned tag to the signal, every train can pass the signal. If you assign a tag, all trains with that tag will be blocked from passing the signal.

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.
