How much of a reduction is a MINIMUM REDUCTION?
6 to 8 pounds
When decreasing the brake pipe pressure what happens to the cars in the train?
Brakes apply throughout the train.
What is the normal position for the retainer valve?
When setting up for trail what position does the independent brake handle need to be in?
When is a locomotive consist brake test required?
Any time the consist is made up or added to.
Is it ok use the PASS position on the automatic brake cutout?
What is the position on the automatic brake valve that gives the max braking effort, without putting the train into emergency?
How much of an increase in brake pipe pressure is required for brakes to start releasing?
1 1/2 to 2 lbs.
What are the 4 gauges on the locomotive?
Main Reservoir, Equalizing Reservoir, Brake Pipe, and Brake Cylinder.
What are the steps for a standing locomotive brake test?
- Place independent brake in Full Application.
- Place reverser in forward/reverse.
- Flip generator field switch UP.
- Place throttle in notch 1.
When is a standing locomotive brake test required?
- When taking control of locomotives.
- When changing ends.
- Initial movement when cutting away from train/cars.
Which gauge should you watch for brake pipe reduction and why?
Equalizing Reservoir, because the brake pipe reduces at a slower rate than the equalizing res.
When should the automatic brake be cut out? (3 situations)
- Checking brake pipe leakage.
- Setting up locomotives for trail.
- Setting up a helper locomotive to assist a train.
When reducing brake pipe past Full Service will you receive any additional braking effort?
Where should you write down the results of a dynamic brake test?
Brake slip/ certificate
When in a penalty application of the brakes and the PC Switch is on, when is the power eliminated?
If the leading engine issued emergency and the PC light is on, when is the power eliminated?
When a train line application is the cause of the emergency application when is the power eliminated?
After 20 seconds.
If a Helper engine is the cause of the emergency application when is power eliminated?
Power is immediately eliminated on the helper engine.
When doing a Running Locomotive Brake Test and applying the independent or automatic brake what should you watch for?
Brake retardation and brake cylinder pressure
When doing a minimum reduction on the automatic brake how much air going to be in the cars brake cylinder?
10 to 12 lbs.
When performing a Standing Locomotive Brake Test and you lose control of the engines what should you do?
- Tie hand brakes if possible.
- Change reverser to opposite direction And place in throttle #1.
When should a running brake test be done?
- When changing ends.
- Initial movement.
- When changing consist.
What 3 pressures will be the same when making service equalization?
- Brake pipe.
- Brake cylinder.
- Auxiliary Reservoir.
What is the pressure of the Main Reservoir?
130 to 145 lbs.
What is considered a reportable condition for locomotive brakes?
2 inch difference than on line 10 of blue form.
What is the position of the automatic handle when adjusting the equalizing res?
Cut out and in RELEASE.
What are 2 things to watch for when doing running locomotive brake test?
- Retarding effect eliminated.
- Brake cylinder pressure reduced to 0.
When doing a running brake test how much automatic brake reduction is needed?
