Signals in the advtrains interlocking system are positioned - like in real life - at the border of track sections. -

When you set up a signal, do the following steps: -

    4. -
  4. Right-click the TCB, and click “Assign a signal” on this side. +

    Every signal is associated to a track on which the instruction should be followed. Signals are usually placed right next to the track on the +right side. Human observers do know then that the signal belongs to the track left of it, however, train safety systems (like the one in +advtrains) can not. +

    This is the reason why a so-called “influence point” needs to be assigned to any signal that should actually give instructions to trains, +should the driver (if even there is one) fail to recognize the instructions. +

    Depending on the signal and the mod that adds the signal, there are different ways to configure this. Signals integrated into advtrains +behave as follows: +

      +

    • Punch the signal.

You can assign a signal to each side of a TCB. This is, for example, useful when creating block sections on a bi-directional main running -line. -

All signals that are assigned to a TCB can be configured by first right-clicking them, then selecting “Influence Point” in + the signalling formspec. +

The small formspec that opens allows you to set and later view or clear the Influence Point. To set the influence point, click the “Set” +button, face towards the signal and punch a rail about 2m in front of the signal. A small marker will be shown, indicating success. To +cancel setting an influence point, punch anything other. (note that then the influence point remains unset, regardless of its previous +state) +

The advtrains-internal train safety system ensures that the train always obeys any restrictions imposed by signals, if (and only if) the +influence point is set properly. +

+ +

3.2 Main + and + Shunt + signals + +

While static signals are mainly used for speed restrictions, the interesting ones are variable signals. Of course, you can always control any +variable signal by traditional means (mesecons, digiline, right-click) if the signal allows it, but that misses the point of this interlocking +system. +

In the following sections, we will talk about main signals. By this, we mean a variable signal that can display both a “Danger” aspect +(trains are not allowed to proceed) and at least one “Proceed” aspect (train may proceed as train/shunt move, with optional speed +restriction), which act as an “entry signal” for one or multiple routes. +

3.4 Assigning + main + signals + to + TCBs + +

Main signals in the advtrains interlocking system are positioned - like in real life - at the border of track sections, because routes also start +and end there. For advtrains to know from which signal which routes can be set, you need to assign the signal to a +TCB. +

To do this, perform the following steps: +

    +
  1. If not already happened, set up a TCB (you don’t need to, but are advised to, configure track sections there) +

    4. +
  4. Right-click the TCB, and click “Assign a signal” on this side. +
    5. +
  5. Punch the signal.
+

PIC +

If you haven’t set an influence point for the signal yet, the influence point formspec automatically opens. +

You can assign a signal to each side of a TCB. This is, for example, useful when creating block sections on a bi-directional main running +line. +

Only main signals can ever be assigned to TCBs, because static ones can either not display “Danger” or do not permit to proceed at +all. +

The Sht2 route then needs to show a shunt aspect, which instructs the driver to proceed slowly and watch out for vehicles on the route. To show a “free” aspect here would be wrong, because that would mean that the track is free until the next main signal, which it is clearly not. -

Please note that reversing a train outside of stations is not only discouraged, but also very dangerous, because even +real-world interlocking system do not expect this.

4.1 Train + Safety + System + +

The Train Safety System, called “LZB” in the code (from the german term Linienzugbeeinflussung, although this is a completely different +system), ensures that trains obey any restrictions imposed by signals when influence points are set. This way, it is not possible to pass +signals at danger or to bypass speed restrictions. +

It is possible to overrun red signals, if a route is cancelled while a train is approaching. Real interlocking systems use a mechanism called +Approach locking for this, however, as of now, there’s no similar system in this mod. If a red signal is overrun, the train brakes using +emergency brake (“BB”) and can not be moved any further. You should then examine the situation and drive the train backwards out of +the section. +

As of now, changing the driving direction of a train always clears any imposed speed restrictions. +
