When may a driver enter the danger zone?
When necessary provided:
- Have completed Reactive Track Access Request Form (if necessary)
- Are wearing appropriate PPE
- Have identified POS in case rail traffic approaches
Is an Emergency Refuge a position of safety?
No
What is a Restricted Location?
Where access to a POS cannot be achieved within 10 seconds of seeing approaching rail traffic
What is a viaduct?
Long bridge consisting of multiple spans with total length over 100m
When can you leave a POS?
- When rail traffic has passed
- You are certain you won’t be in danger
What is an Underbridge?
Used when road traffic or waterway goes UNDER the rail tracks
What is an Overbridge?
Used when road traffic goes OVER the rail tracks
What are sleepers made from?
Concrete, steel or timber
What is the function of ballast?
To provide drainage and support/holding the track
What is the function of the sleepers?
Distribute weight onto the ballast, maintains correct gauge
What is the function of the rails?
To guide trains through interaction with wheel flanges
What is Dual Gauge?
Tracks with three rails so standard and broad gauge trains can run
What do the Kilometre Posts signify?
How many kilometres you are away from Southern Cross Station
What are Overhead Structure Numbers?
Times the number by 100 to know how many feet you are from FSS
(Every stanchion is numbered)
What is a bi-directional line?
Where trains can travel ‘up’ and ‘down’ on same line
What is a double line?
Two lines where one line is generally used for ‘up’ and the other for ‘down’.
What are multiple lines?
Three or more lines.
Increase hazards as more trains will be running from both directions
What are Turnout Points?
They are a means of altering the route of trains, not necessarily to another line
What are Crossover Points?
They are points that allow trains to cross from one line to another
Where is the Inner Suburban Area?
Between North Melbourne, Jolimont and Richmond platforms
One third of railway incidents are caused by what?
Communication errors
What is ‘active listening’?
Where you make a conscious effort to understand not only the words being said but the complete message
In Safety Critical Communication, how do we demonstrate active listening?
By repeating back the message
Over coms, how do we say ‘no’?
Negative
Over come, how do we say, ‘yes’?
Correct
What are the basic hand signals?
‘Stop’ and ‘All-right’
What are the driver’s responsibility to an electric shock victim?
- Safety to themselves
- Safety to passenger
- Isolate power
- Attend to victim
How do drivers keep themselves safe from electrical items in sidings and yards?
Keep a safe distance from them.
What is the exclusion zone for personnel near live apparatus?
2 metres
How many volts in the traction power system?
1500v DC
What is the voltage supplied from the power grid to the substation?
22,000v AC
Overhead structures:
What is the stanchion that forms a complete arch?
Portal stanchion
What kind of stanchion looks like an F-shirt?
Cantilever Stanchion
What are the stand-off stanchions used for?
To keep the overhead in position around curves
What does the transmission wire do?
Distributes 22,000v AC along the rail corridor to the substations
What holds the contact wire in position from the stanchion towards the centre of the track?
Steady arm.
(Staggers in zig-zag pattern to prevent excessive wear)
Who manages the overhead power system?
Electrol
What are Spark Gaps?
Safety device that enables power to return to the substation in the event of a fault occurring – similar to safety switch
What are the three types of Section Insulators?
- Fibreglass
- Porcelain
- Wood
When would Section Insulators be used?
If a section of the overhead power needs to be isolated
What do guy wires do?
Attach to the ground and provide stability to stanchions, often where catenary/contact wires terminate
What are the two types of tension structures?
Spring type and weighted
White star symbol with black dot in middle?
Terminal Stop Sign
Where are Terminal Stop Signs placed?
15m from where a pantograph leaves the contact wire
Where does a driver stop in relation to a Terminal Stop Sign?
at least 3 metres before
Faults that may occur in overhead equipment includes: (6)
- Loose or hanging wires
- Obstructions
- Water flowing onto overhead conductors
- Sparking between pantograph and contact wire
