Placing Signals


General Placement

  • The red arrow indicates where the signal is placed.
  • It can be used as a handle to move the signal along the track.
  • The signal’s offset (position left or right of the track) can be adjusted in the properties window.

Overlap

  • Signals have a 20m overlap.
  • If a signal is placed closer than this distance to the signal in front then it will repeat the state of the signal ahead (if able). This can be used as a way of providing Co-acting or Indicator signals without needing any extra setup.
  • If a train occupies this overlap region then the previous signal (in most cases) will be held at stop.

Defining Routes

Standard Turnout

  • Turnout routes are defined using the standard Direction Targets.
  • Straight, Left 1-3 and Right 1-3 targets may be used.
  • A route table in the signal properties window lists how many routes are available and which target to use.
  • The top route is the default route if no targets are placed.
  • The Danger target or a direction marker pointing towards the signal can be used to block the signal from clearing down that track.

High Speed Turnout

  • Most turnouts in NSW have a slower speed than the main or continuing route. In some cases however, the speed limit may be of equal speed. This is known as a high-speed turnout.
  • Use a High-Speed modifier target before the direction target to define a high-speed route.
  • Note that this is only possible with Diverge signals fitted with a Main Line Route Indicator unit.

Low Speed Turnout

  • In some cases, permission to take a diverging route may be given by a Low Speed indication.
  • Use a Low Speed modifier target before the direction target to define a permanent low speed route.
  • If the signal is fitted with a Small Route Indicator then the text for that route will also be illuminated.

Shunting Route

  • Subsidiary shunting routes can be permanently defined by placing a Shunt or Shunt Ahead modifier target before the direction target.
  • This removes the need for custom driver commands to be used if a route is always accessed by authority of a shunting movement.
  • Regular ground shunting signals (with the exception of intermediate shunting signals) do not need the shunting target.

Overriding Routes

  • Some situations will require multiple signals to point to the same track but require different direction targets for each signal.
  • To help workaround this, a special Route Override Target may be used in place of the standard direction target.
  • The override target is linked to the corresponding route in the signal’s route table.

Advanced Warning

  • If additional warning is required between signals then an Advanced Warning Target may be used.
  • For single light signals, this adds a Medium indication when the next signal is at Caution or Caution Turnout.
  • For double light signals, this will add a Preliminary Medium indication when the next signal is at Medium or Medium Turnout.

Controlling Signals
In most cases, the signals will be able to operate on their own without additional setup (with the exception of placing direction targets for junctions). If additional control is required however, the signals are compatible with Interlocking Towers and Driver commands. See the post Ranger_51's Signal Kit | Signal Assets for references to which signal state to use.

If an Automatic/Controlled signal is controlled by an Interlocking Tower (and not set to Automatic) or set via a Driver Command then the “A” light will be extinguished.
Interlocking Towers

  • It is advised that all trackwork and signalling has been finalised before setting up an interlocking tower.
  • Setting the signal to Automatic will allow the signal to function as normal and be able to automatically determine which route is set (based on the route target). This is the recommended setting.
  • Alternatively, you may select a specific signal state to be displayed. In most cases, this means the signal will not perform additional checks for which route is set or respond to signals ahead.
  • For shunting routes, set the state to be used as “Proceed at Medium Speed”. The signal will display a shunt indication and then automatically check ahead for the correct route target.

Driver Commands

  • Use the “Set Signal Ahead” or “Set Selected Signal” commands to change the state of the signal ahead.
  • For shunting routes, the signal will perform an additional check to determine which route is set.
