Banner type indicator. Provide the driver with an early indication of the signal indication shown on the signal ahead. Failure of banner indicator? |
Should one or both indicators fail to display and indication, Driver must consider next fixed signal is displaying a “Stop” indication and regulate the speed of the train accordingly. Notify control with defective banner number. |
|
|
Failure of LED active speed board. |
Signaller will notify drivers of affected trains of the fault. |
|
|
If driver observes a signal which is displaying a proceed indication and the route indicator is not illuminated, the driver must confirm with controlling signaller the route to be taken. Must attempt to stop if there is sufficient time to stop safely, if not proceed in usual manner, setback moves require correct authority. |

Types of route indicators. |
Large theatre boxes-display a letter/s, dual gauge indicator V/S, feather, illuminated/ painted arrow, stop boards, location board, derail, dice loop, speed indicator. |

Speed boards. “G” applies to trains with vehicles in the consist with the last letter classification ‘A or Z’ “F” applies to trains that have no vehicles in the consist with ‘A or Z’ “P” applies to passenger trains. |
Curve boards indicate the maximum allowable speed a train can travel around the curve. Cannot accelerate until entire length of train is clear of the curve. |

Approach section indicators signs are located at the beginning of track circuits that control the operation of the crossings protection equipment. Located where shunting takes place. If the driver allows the train to pass this sign the level crossing warning equipment will activate. This sign is a white reflective diamond shaped sign with a black diagonal cross. |
Minimum clearance signs. Sometimes the clearance between track side infrastructure and the side of the train is less than the minimum required. A horizontal white reflective board with black chevrons at 45deg is positioned on the infrastructure to warn crews that the clearance is less than the minimum required for work. |

Level crossing predictor signs. Designed to check the trains speed as it approaches the level crossing. This means that the time taken for the train to reach the crossing can be calculated and the warning equipment can be activated at the appropriate time to allow arming of the trains approach and not unnecessarily delay traffic. If the speed of the train is increased between the time the loco passes the board and the crossing, the minimum protection time is shortened. A predictor board is black circle and a cross on a white board. |
The predictor board with a black circle and cross on a white board with the numerals 50. Trains travelling below 50km/h must not increase speed. Trains travelling above 50km/h can increase speed. Should a train stop on the approach to a level crossing the level crossing warning equipment will activate for 15secs and stop. Level crossing will operate again once train moves towards crossing but must wait until booms are level. Should the train be stationary on the approach and the equipment has ceased operation, it will reactivate after 10mins and continue to operate until train has cleared. If occupying the island circuit, level crossing equipment with operate continuously. |
