Signaling guide


Signals in Transport Fever are path signals.

If a train passes a green signal – indicating a free path ahead - the path to the next signal or station is reserved for the train.

When a train passes a signal it will turn red. The following train will stop at the signal, until the train ahead exits the path, the following train is trying to reserve, by passing another signal, leaving the station, or diverting of to another path at switch.

Learn more about path reservation in the examples below.

Signals are only recognized by trains if they are placed on the right-hand side seen from the driver’s perspective. Signals on the left-hand side (seen from the back) are ignored, unless they are configured as one-way signals, not allowing the train to pass the signal at all.

To set a signal to one-way click on the signal and select “One-way: yes”.

Single track configuration

In the example below the train leaving the station on the right reserves the hole path up to the next station.
The path ahead stays reserved while the train is on route.

Passing loop configuration

When a second train is added to this configuration, both get stuck in the station. Despite the passing loop, they will reserve the hole path up to the next stations. As both paths overlap, they cannot leave the stations.
When signals are added on each end of the passing loop, the reserved paths will no longer overlap and the trains can depart.
When they pass each other in the loop, they will reserve the rest of the path and travel to their destinations.
Placing more signals, thus creating more paths blocks, will allow multiple trains to pass each other.
Note that stations also act as signals, if the station is configured as a stop in the trains line. In the example below the station in the middle functions like a passing loop without additional signals.

Dual track configuration

In the example below two lines share the same infrastructure. Double diamond crossovers in front of the outer stations allow trains to change to both platforms. The two lines are guided with waypoints through the middle station to ensure that each line is using its own platform. This allows trains from different lines to use the station at the same time in one direction or to overtake each other.

Path reservation

Example 1

In the example below, the path ahead of the yellow train is reserved.

Note, that only the path in front of a train is reserved. Therefore, the blue train can enter the station, as soon as the yellow train passes the switch.

Example 2

In the example below, both trains are allowed to enter the station at the same time, despite the track crossover, because their paths do not overlap.

Example 3

When paths overlap, it is important, to leave enough clearance after switches or crossings. In the example below, the red train waiting at a signal for a free path a head, blocks the yellow train.

Moving the signal away from the switch, will allow the red train to stop without blocking the crossing. Make sure to leave enough space for the full length of the train.

Left hand drive / right hand drive

It is possible to configure tracks for either left-hand or right-hand driving by placing the signals on the outer or inner side of a double-track.

Semaphore and light signals

Semaphore signals have the same functionality as light signals. An upwards pivoted arm is analogue to a green light, a horizontal arm is analogue to a red light.
