When does wheel slip occur?
When taking power
When does wheel slide occur?
When braking
Can traction sand be deployed at any time?
No, it can only be used when the traction sand button is illuminated
Where should you not lay traction sand?
Over points
Over level crossings
Why should traction sand not be laid over points?
Because the sand, mixed with moisture could create a paste and stop the points from moving
What is WSP?
Wheel slide protection. It works with smart sanders, detects wheel slide, and deploys sand onto the rail to increase friction
Do all brake steps have WSP?
No, WSP is only in brake steps 2, 3 and emergency
When does low adhesion season begin?
Always on October 1st
Does low adhesion season always end on the same date?
No
How often should running brake tests be carried out in low adhesion season?
Frequently
What formation trains are more prone to slipping?
traditionally short formation trains are more prone to slipping
What should you do if you experience wheel slip but the traction sand button is not illuminated?
Remain in a lower power notch for an extended period of time
How would you identify wheel slide?
The speedometer and the brake pressure guague may fluctuate
Following WSP detection (and the subsequent laying of sand to assist braking), what impact will it have on other trains
The application of sand will improve track conditions for oncoming trains
How long do you press the traction sand button for?
5-7 seconds
If ice mode is required, how do you activate it?
There is an ice mode button in the non driving side of the cab. This needs to be pressed for 5-7 seconds, but ONLY WHEN STATIONARY
If rail conditions deteriorate suddenly, and there is sufficient braking distance to stop safely, what brake step should you use?
Brake step 3 (full service)
If rail conditions deteriorate suddenly, and there is NOT sufficient braking distance to stop safely, what brake step should you use?
Emergency brake, and keep it applied until the train comes to a complete standstill.
When driving in inclement weather, when must you be extra careful?
If you are driving the first train of the day
What can cause low adhesion, name at least 5
Foliage
Industrial contaminants
Oil (from traction units)
Grease (from traction units)
Level crossings (debris, salt, grease)
Rust
Water
Frost
Fog
How would a driver be aware of low adhesion areas, name at least 5
Low adhesion leaf signage
Sandite boards
Signs in depot (October 1st low adhesion season starts)
Late notice case (Ice mode/ extreme weather)
Autumn brief pamphlet in pigeon holes
Sectional appendix
Route packs
When does low adhesion season start?
October 1st
When would you brake in low adhesion season?
Earlier (Not earlier and lighter)
When would you perform a running brake test in low adhesion season?
Frequently
