A
50 psi
3
Q
- After inadequate brake performance has been detected and train is stopped, what must be performed to determine the cause?
A
Walking inspection
4
Q
- A train must be brought to a safe stop immediately if main reservoir falls below what pressure?
A
100 psi
5
Q
- If it becomes necessary to cut out brakes en route, calculate the total number of axles in the following train consist: 2 locomotives (P42), 8 passenger cars, and 5 baggage cars:
A
60
6
Q
- What is the maximum authorized speed when operating Amfleet cars with over-inflated air bellows (springs) for movements other than turnouts and crossovers?
A
30 mph
7
Q
- If the brakes become completely inoperative (no brakes on any axle) on front or rear of passenger equipment, what speed must not be exceeded?
A
20 mph
8
Q
- What type equipment is counted when making operative brake calculations with non-passenger equipment if it becomes necessary to cut out brakes en route?
A
cars and locomotives
9
Q
- When cutting cars off only, which of the following is not used to put the equipment left standing in emergency?
A
ABV
10
Q
- With a passenger train en route, what is the minimum percentage of operative brakes necessary in order to continue without applicable speed restriction in effect?
A
85%
11
Q
- On what form must the engineer report locomotive defects before going off duty?
A
MAP 100
12
Q
- From what location do emergency applications initiate when the EOT emergency toggle switch is activated?
A
rear of train to the front
13
Q
- Anytime brakes are cut out, what is the procedure in order to confirm the percentage of operative brakes?
A
Perform a walking inspection of a brake application
14
Q
- If a train breaks in two, after re-coupling and testing the air hoses, what air brake test must be made prior to movement?
A
Passenger Class II/Non-passenger Class III
15
Q
- Following and emergency brake application, what air brake test must be made after proceeding?
A
Running brake test
16
Q
- In accordance with AMT-3, what is the first step to be taken by the engineer after a train breaks in two and an emergency radio transmission is made?
A
If equipped, shut down and isolate HEP as soon as possible
17
Q
- Besides applying all hand/parking brakes on all locomotives, how is the generator field switch/breaker to be positioned on an unattended locomotive that is supplying compressed air and coupled to cars?
A
Place switch in OFF/DOWN position
18
Q
- What brake test is required whenever a control valve or brakes are cut out on passenger or non-passenger trains?
A
Passenger Class II/Non-passenger Class III
19
Q
- Under non-passenger train rules, what is the method used to calculate the percentage of operative brakes?
A
Divide the total number of operative control valves in the train by the total number of control valves in the train, including locomotives
20
Q
- When must an emergency function test of the two way end of train device be conducted?
A
Whenever the LCU or EOT is changed or at point of installation
