Q

How does a driver check if a back-trip has occurred from the leading cab? (4)

A

54
Upon reaching a Predictor Board, what instructions must a driver follow?
When a driver reaches a Predictor Board, they must not increase their speed until the train has entered the level crossing
55
What is the definition of a Long Whistle?
"The sound of the whistle should be distinct, with intensity, duration or repetition appropriate at which the warning is required to be heard"
56
How should a driver operate the whistle if two trains are approaching a level crossing at the same time?
Both drivers should sound continuous whistles until both trains have reached the crossing
57
How should the driver operate the whistle if they are approaching a level crossing where a road user may be in danger?
They must make a series of short, urgent blasts on the whistle
58
What emergency action should a driver take if they see potential danger at a level crossing? (3)
- Apply emergency brake - Sound continuous whistle - Report incident to Train Controller
59
What must a driver do if approaching a level crossing where the protection equipment has not operated? (4)

60
If, due to disruption, a train is required to be running "wrong line" through a level crossing, what must a driver do to ensure safety of the crossing? (3)

What do the Coasting, Series and Series Parallel Indicators communicate to the driver?
Comeng trains only: Coasting = driver to shut power off on master controller and coast (roll) Series = driver to select Series on master controller Series Parallel = driver to select Series Parallel on master controller
76
Why do we have Coasting boards?
To minimise electricity usage and aid in the maintenance of momentum.
77

- Coasting - Series - Series Parallel
78
Where are Coasting Boards located?
On stanchions
79
What does a Section Board indicate?
The defined end of a signalled area

The ideal stopping point for that platform.
83
