Object description
The rail signal divides rails into blocks and allows locomotives to react to other locomotives, allowing multiple trains use the same rails without colliding. Blocks span all connected rails regardless of whether a train can actually travel between them. Rail signals can also be used in with conjunction rail chain signals, which also separate rails into blocks. In addition to the explanation on this page, there is also the rail signal tutorial.
Direction
Signals go on the right side of tracks and allow travel in that direction. An automatic train will not enter a block with signals only on the left side. Two signals directly opposite each other allow trains to travel in both directions through that point. The signal position directly opposite an existing signal is highlighted in white when the player has a rail signal in their hand.
States
Rail signals have four states:
- Green - The monitored block is empty.
- Yellow - A train is not able to stop before the monitored block and will pass the signal. The debug option
show-train-braking-distancecan be used to see the distance locomotives need to stop. A yellow signal means that a train is approaching and already has the approval to enter the following block. The block is reserved for a train and all other entrance signals of that block turn red. - Red - The monitored block is not empty or another signal monitoring it is yellow.
- Blinking - The signal is not on a rail, or the monitored block is also the block before the signal.
When a signal is red, locomotives will stop before it. A rail chain signal can be used to make locomotives stop earlier, as they will always mimic the signal of what is in front of them.
Circuit network
A circuit network condition can be configured that when true will make the rail signal red.
A rail signal can also output three different signals depending on if it is in its green, yellow or red state. If a rail signal is red because of a circuit network condition the rail signal won't output a circuit network signal.
History
- 0.13.0:
- The rail signal is now connectable to the circuit network.
- Halved the mining time of the rail signal.
- Train stop placement indicator added during rail signal placement.
- 0.11.4:
- Rail signal that fails to divide two sections of rail will blink multiple colors.
- 0.9.0:
- Players no longer collide with the rail signal.
- 0.5.0:
- Players can now see a visualization of the protected rail area when building/selecting the signal.
- 0.4.1:
- Rail signals connect to more than one rail when connected to a junction.
- 0.4.0:
- Introduced
