Handle Off position
When in Helper Service and a back-up movement exceeds one mile, who must control the trains air brakes?
The Engineer of the HELPER locomotive.
When in Helper Service, the lead engineer must make certain that all other engineers are informed of what? (3 Items)
A. Planned Speed Changes.
B. Signal Indications.
C. Any other condition that may affect train movement.
Only locomotives with which type of couplers can be used for Helper Service?
Alignment Control Couplers.

Class III - Trainline Continuity.
The MAIN RESERVOIR pressure is within 15 PSI of the Regulating Valve Setting. To increase the air compressor output on a locomotive consist with a least one Electrically-Driven Air Compressor, what should be done with the REVERSER and THROTTLE?
THROTTLE in position 1.
MAIN RESERVOIR pressure must be at least ___ PSI more than the BRAKE PIPE pressure for the air brake to work properly?
The MAIN RESERVOIR pressure should be between ___ and ___ PSI?
130 and 145 PSI.
A. While using qualified telemetry, how can it be observed that the brakes are applying on the rear of the train?

A. a 5 PSI BRAKE PIPE reduction.
- B. a 5 PSI BRAKE PIPE increase.
- (ref 5105)
What 3 methods can determine that air brakes at the rear of the train have been applied or released?
1. Telemetry that is qualified as accurate shows a 5 PSI reduction/increase in BRAKE PIPE pressure.
2. Cylinder Piston Travel.
3. Observing a BRAKE PIPE gauge at the rear of the train.
A. If a freight car fails an air brake retest at the originating location, what should be done with the car?
B. If a freight car fails an air brake retest at an intermediate location, what should be done with the car?
A. Set the car out.
B. Once tagged, it may be moved to the NEAREST repair location.

When must the emergency capability of Two-Way Telemetry be tested?
When either or both devices are installed.
TRUE or FALSE:
While the train or engine is moving, the engineer must not adjust the regulating valve on the controlling locomotive, or cut out a brake valve on the controlling locomotive?
While performing a Class I Brake Test, how much of a reduction is made to the BRAKE PIPE?
