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 and then just dragging them along the track or delete selected signals by pressing [delete]. Every signal type has its own menu for editing the properties, you can access it by selecting the signal and looking at the menu on the top left. There you can change the type of the signal, flip it or edit additional settings. Pressing [F] while signals are selected will also 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.

Block balise menu

Platform train stop point [2]

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

Block balise [3]

Block balises stop a train path check or path reservation from going beyond their point on the track, that happens 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, which is purely a cosmetic option and has no gameplay effect. The third option lets you choose how the balise should work. The option selected by default is the most frequently used option and behaves as described above. There is also a panel where you can assign tags to the balise.
The two options and how they interact with tagged trains are:
Applies to all trains: This is the default option. If you assign tags to the balise, it will work normally for all trains that do not have any same tags assigned, but it will be ignored by trains that do have at least one of 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 work like a normal balise for any train, that has at least one tag in common with the balise.

Path signal [4]

Path signal menu

When a train arrives at this signal, the signal will check the path of the train (visible in a map mode). If this path intersects with another train's path, the train will be stopped and the signal will turn red. The signal will check again until the path is cleared and lets the train pass afterwards. The path signal will check the path up to the next path signal facing the same direction or the next balise along the track.
The bound option:
Only for same direction:This is the default option. The signal will let paths through that are against its own direction, but block every path that is going the same direction.
Always:The signal will block every path from every signal, ignoring their direction. It can also be used by trains from both sides.

As with the balise, there is a cosmetic option to shift the signal to either side.
There is also an option to set a time after which you will be alerted about a waiting train. This is a global setting, and will be the same in every save, you can also set a custom time between 0 minutes (which alerts you instantly) and 24 hours.

No-way [5]

No-way signal menu

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