Study Notes
Hazardous Materials
- Materials transported by rail posing significant health, safety, or property risks.
Air Hose
- Flexible pipes connecting vehicle headstocks.
- Enabled by couplings, allowing pressurized air flow for brake function.
Angle Cock
- Valve at the air hose's fixed end, operated by a rotating handle.
- When open, it allows air flow through the hose.
- When closed, it prevents air flow through the hose.
Automatic Coupling
- Vehicle coupling device requiring no manual handling.
- Operated by a single release lever controlled by the shunter from a safe position.
Brake Reservoir
- A tank storing air used for brake operation.
Draw Gear
- A general term for coupling and draft components.
Dummy Coupling
- A fitting attached to an air hose coupling head when the hose is not in use.
- It secures the hose and prevents dirt/moisture ingress.
Shunting
- Moving and positioning rolling stock within a yard based on operational or maintenance needs.
Vehicle(s)
- Any rolling stock item(s).
Abbreviations and Full Forms
- CCID stands for Car Control & Identification Device.
- ECP stands for Electrically Controlled Pneumatic (Brakes), meaning the brakes are controlled by electricity and use air pressure.
- PPE stands for Personal Protective Equipment, which includes items like gloves, helmets, goggles, respirators, and high-visibility clothing, worn to protect workers from hazards in their work environment.
- RSM stands for Rolling Stock Maintenance, which involves the regular maintenance of trains, trams, and other railway vehicles.
Automatic Brake - Requirements
- Defective automatic brakes must be repaired if possible.
- A vehicle with a defective automatic brake can continue to its destination only if RSM authorizes it.
- A discharged tank wagon can make another journey to a maintenance facility.
Handbrake Requirements
- Handbrakes must be applied to rakes of wagons.
- The number of handbrakes required depends on the number of wagons:
- 3 handbrakes for 1 to 30 wagons
- 10% of the number of wagons for 31 wagons and over
- The shunter must ensure that the SAR Train Driver has checked the Fire Screen Event Log for handbrake status.
Piston Travel Indicator
- A Piston Travel Indicator visually confirms brake application or release.
- The indicator is located on each bogie.
- The indicator can be viewed through the bogie frame or over the top of the bogie.
Brake Release Confirmation
- Brake blocks remain in contact with the wheel when brakes are released.
- This makes it difficult to confirm brake release visually alone.
- Other indicators like the piston travel indicator and handbrake chain should be checked.
- A loose handbrake chain indicates the handbrake is not applied.
### Reporting a Rail Dangerous Goods Emergency
- When calling the OCC for a rail dangerous goods emergency, start by clearly stating: "THIS IS A RAIL DANGEROUS GOODS EMERGENCY"
- Provide the train reporting number, if applicable
- Specify the location of the incident
- State the time of the incident
- Describe the incident in detail
- Unless the incident is minor (no damage to the wagon, tank, container, or flask), advise the OCC to stop all trains passing on adjacent lines.
- Indicate whether any Rail Staff or members of the public are involved.
