Shunting Flashcards
What does foul mean
When a rail vehicle or object is not clear of adjacent line
What does make good mean?
Preparing rail traffic for departure by making sure rail vehicles are coupled correctly, hose bags are connected, air taps are in correct position and spare hose bags are secured to the dummy connection
What is a rake (string)?
A number of rail vehicles coupled together
What do two white shunt lights mean?
Authority to proceed to:
- LOS board
- next intervening signal
- as far as the way is clear
- signal tells us points are housed against the stock rail (but NOT in which direction)
Restricted speed of maximum 25 kn
What are the NINE shunting commands
- Stop
- Danger
- Move away
- Move towards
- Move away slowly
- Move towards slowly
- Admit
- All clear
Rules to follow when giving shunting commands
- Use radios
- if radio fails use hand signals to stop train
- re-establish radio communication before shunt movements recommence
- if radio comms are restricted to one single channel the shunter conducting the shunt movements must wait for the channel to be clear
Level crossing driving rules
- can go 10 kms while on crossing
- leading vehicle must be clear of crossing then can go 25kms
- workers must not direct road traffic
What is a passive crossing?
Only have signal (stop or give way) that are visible on approach. This signals is unchanged and has no mechanical aspects or devices
What is an Active level crossing?
As well as passive, they have mechanical devices e.g- flashing lights, automatic gates, audible devices.
Wagon components
- Bogie
- Brake components
- Automatic couplers
- Draft gear
- Headstock
- Wagon frames/Chasis
BBADHW
Wagon Frame/Chasis
Load bearing structure that carries the weight and absorbs Draft forces of the wagon.
Where is the B end located on a COAL train?
At the end closet to the park brake
Where is the B end located for a FREIGHT train?
The direction the piston is pointing
-Headstock
-Equipment carried on headstock
At either end of the wagon, used to join wagons together.
Equipment carried on headstock:
- Automatic couplers and release levers
- Air hoses
- Dummy couplers
- Couplers
- Air isolation cocks
- Knuckle
- Knuckle pin
- Draft gear
- Shank
- Headstock stock cocks
- Brake pipe
- Main reservoir
Automatic couplers
Name the two types
- Are fitted to both ends of rolling stock to attach and detach
- Top list and bottom lift
Main parts of Automatic couplers
- Coupler Head
- Guard Arm
- Knuckle
- Knuckle Pin
-Shank
-Locking block - Automatic Lifter
How together safety information?
- HOWED (SHE) - HOWED is online reporting of SHE
- pre-start briefing
- safety board
- emails (notices and alerts)
- toolbox talk
What is a shunter responsible for?
- preparing and communicating a shunt plan
- performing the shunt as per shunt plan
- Applying local operating procedures
Why do we perform stretch testing?
Done after coupling up.
To make sure couplers are locked and pins are down.
Components of air braking system
- Triple valve
- Release valve
- Brake booster
- Brake beam
- Brake block
- Brake cylinder
- Load compensating device
- Hose bags
- Main reservoir
- Axillary reservoir
- Branch pipe isolation cock
- Pipe supply
What is a Dummy Couple and why do we use it?
- Device and air hose can be attached to when not in use
- Prevents damage to airbase and infrastructure when travelling and stops dirt and debris getting into the hose
