BRAKING INSTRUCTIONS (WSP) Flashcards
What information should be considered when braking under good rail conditions? 3 answers
Train speed
Environmental conditions
Passenger load
At a braking area, what must the first application of the brake be?
Step 1 or step 2
Prolonged use of brake 1 (from high-speed braking) causes what to happen to the brakes?
It causes brake fade.
When braking, if necessary, what brake step should be applied?
Step 3
How can you stop the train from having an abrupt stop when bringing the train to a stand?
Momentarily releasing and then re-applying the brake just before the train comes to a stand.
As a driver, how can you increase rail to wheel adhesion?
Using the manual sander
Why must you resist the temptation to partially release the brakes when applying WSP?
If you release the brakes, they will prevent the WSP and automatic sander from doing their job.
The WSP is linked to the speedometer, so if the reading drops to 0MPH and holds, what does this mean?
The wheels have locked and the WSP system cannot detect this.
How would you get the wheel to rotate if it is locked?
Release the brake momentarily, before immediately making another brake application.
When must you apply the manual sanding button, if required to use it? And why would you do this?
Just prior to applying the brake.
This allows sanding to commence immediately when the brake is applied. It means the wheels will be running on sanded rails before the brake starts to ‘bite.’
What will the use of the emergency brake ensure regarding electrical feeds and the sander?
It will ensure that any false electrical feeds are eliminated. It will also allow the sanders to work automatically.
