SAY AGAIN
Please repeat all of your last statement
26
LOUD AND CLEAR
Your signal is strong, and every word is understood
27
STANDBY
Wait. I will be back to you soon
28
Documentation that should be accessed prior to an arrival/departure roll-by inspection
Train consist, train identification number, loco numbers, wagon identification information, loading information, dangerous goods information
29
Reasons for Accessing the train consist information
Confirm the train is correct and assist with making corrective decisions if required
30
Documentation for after a roll-by inspection
Record relevant documentation and in own route records, terminal log (if at terminal)
31
Information to record for roll-by inspections
Date, time, train/lead locomotive number, location, outcome
32
Environmental conditions to be aware of while performing roll-by inspections
Time of day (night), infrastructure arrangements/ground conditions, weather conditions, long grass, ballasted banks, uneven ground, level grossing/local traffic
33
When defects are detected during a roll-by
A closer inspection is needed and the situation assessed for safety requirements and to determine any potential operating requirements or repairs
34
When a train needs to be stopped for a closer inspection you need to create
a contingency plan
35
A contingency plan must include
Who and what information to communicate, any safeworking requirements or impacts to 'normal running', personal safety, personal isolation to the train or train, tools, PPE
36
Information needed prior to entering the 'Line of Fire'
Track protection for train movements on adjacent lines, three step protection is in place, type of loading (Dangerous goods, glass), Stored energy (sprung steel), risk of being burnt by hot metal parts (wheel faces, brake blocks), a safe evacuation route, method of communication
37
With respect to dangerous goods, if you need to access the Line of Fire
complete a visual inspection of the wagon side checking for DG placarding, Communicate with the Driver to check the load sheet for the wagons in question and those either side for DGs content
38
If you suspect there are dangerous goods in a wagon you need to approach
DO NOT approach until you confirm it is safe to do so
39
The correct loading and securing of all freight is essential to
prevent injuries to employees and the general public, prevent damage to property, prevent damage to customer freight, ensure on time delivery of goods, prevent movement in any direction
40
Devices used to secure freight
chains and ropes, webbing and straps, gates and doors, container locking devices
41
When checking and securing devices, you should be alert for
securing devices which are not firmly done up or safely stowed, fraying knots in straps or chains, doors and gates which are not closed or secured or which are damaged
42
Number of twist locks that need to be secured per container
4, one per corner
43
At all times you should be checking to make sure loading
has not shifted, is not poorly or insecurely attached, is still inside the guage requirements for the network
44
Out of guage loading
a load is outside the allowable dimensions
45
If a wagon is safe to travel, all containers must be
in a safe sound sound condition, properly secured, loaded correctly, not leaking
46
Locking devices used to secure containers to wagons
Portable anchor brackets, retractable fixed twist locks (hinged/pop up), automatic twist locks, portable or marine twist locks
47
End of Train Matker (ETM) or Electronic Train Air Sensor (ETAS)
a device placed on the loast wagon of all trains before they depart
48
Why use an ETM?
Signal to the driver of a train travelling behind that they are approaching the rear of a preceding train, visual indicator that the train is complete
49
Benefits of a ETAS
gives train driver an indication of the status of their train by providing an end of train brake pipe pressure reading in the Loco cab
50
Skidded wheels
Occurs when an axle or wheel locks up while the train is moving
51
Skids lead to
further wheel damage and reduce the life of the bogie components
52
To detect a skidded wheel, be alert for
a wheel that is not rotating, smoke, unusual sounds (banging), an unusual smell of hot metal, bouncing of a wagon
53
Wheel Scale
a build up of metallic material on the wheel tread
54
Usual cause for wheel scale
sticking brakes
55
To check for scaled wheels, be alert for
Unusual sounds (banging), bouncing of the wagon, an unusual smell of hot metal
56
Wheel bearing
transfers the weight of the load to the wheel set. Usually contained in the axle box
57
Hot box
overheating of the bearing/axle journal/axle box assembly
58
Cause of Hot box/bearing failure
Lack of lubrication
59
Implications of not detecting a failed bearing (hot box)
the bearing may melt the journal and collapse or "screw off" or more commonly referred to as a screwed journal. This will cause a derailment
60
To check for axle box/bearing failures, be alert for
Grinding noises from the bearings being crushed, heat caused by metal melting, smell from the melting metal and possible accompanying skids and scale
61
Bogie
the part of the wagon which holds the wheel sets and brake equipment and supports the weight of the vehicle
62
When performing the roll-by inspection of bogies, you should be alert for
loose or missing safety loops, broken or missing springs
63
Brake rigging
the system of rods, levers and brake beams on the bogie which connects the cylinder with the brake block on the wheel
64
Dragging or damaged brake rigging indicates
that there is no brake on the vehicle which can lead to derailment and/or damage to the track
65
To check for issues with brake rigging, be alert for
dragging rods, levers and brake beams
66
Implications of air leaks
The braking of the train is affected
67
To check for air leaks, be alert for
the sound of escaping air from connections, smell or visibility of smoke
68
Implications of air brakes/hand brakes not being released
overheating occurs and can lead to locked/skidded wheels
69
to check for brake release issues, be alert for
Air brake cylinder pistons not in the release position, air brake blocks against the wheel, handbrake chain is not hanging correctly (smiley face)
70
Smoke and fire during a roll by inspection could be caused by
a fire in the loading, changed condition in relation to a load of dangerous goods, overheated bearings, locked wheels, dragging brakes
