Troubleshooting Flashcards
Regarding SMEE type equipment, if a train fails to take power with T/O’s indication illuminated, what should a Train Operator do to attempt to take power?
- Reset the control cutout circuit breaker
- Make sure the train is charged
- Swipe the reverser and place the train’s brakes into emergency and re-charge.
- Push the door bypass button
If a train cannot move under its own power, the following train may be coupled to it if both have the same type of coupler. Under no circumstances should these trains be coupled:
Electrically
A T/O at a terminal attempts to move the Master Controller handle to a power position and is unable to, the T/O should check to ensure that the:
Reverser has been thrown to the forward, and the Control Cut Out circuit breaker is cut in.
After making a station stop, the 3rd rail power is removed. How would the T/O become aware of this?
Air conditioner blowers & air compressors will not operate
The term “operate at RSEC” means?
10- 2- 1/2- S- F- U-
After making a proper station stop, a T/O looks out of a cab window towards the rear of the train and sees a steady yellow light illuminated on the 2nd car. The probable cause of this would be:
A dead motor(s) on the 2nd car.
If a master controller becomes stuck in “series” or “multiple” position, the T/O should:
Turn off the control cut out circuit breaker and stop train
If the T/O must cut out the breaks in the 1st or last car, they must also:
Remove the train from customer service
A C/R loses indication in the rear section while the train is in motion. The C/R passes one (1) long buzzer signal to the T/O to stop the train. The T/O checks his/her indication, and it’s illuminated. What could have caused the loss of the C/Rs indication?
A burned out C/Rs indication bulb in the MDC panel
A T/O experiences brakes in emergency, after moving the master controller to the “off” position and placing the brake valve handle in emergency, what action should be taken by the T/O next?
Notify RCC of the situation while simultaneously attempting to recharge the train
A T/O operating from other than the front car must not advance the controller beyond which position?
Series
To properly cut out motors on a subway car, which of the following circuit breakers must be placed to the “off” position?
1 thru 8 + GS
When a T/O is required to sectionalize a train, they should:
- Close the brake pipe & straight air pipe angles in the middle of the train
- Retrieve & Lock back the electric portions in the middle of the train
- Attempt to determine the good section
While closing the side doors, if all the doors in one car fails to close, the cause could be the:
DC1 or DC2 circuit breaker is tripped in that car
Regarding SMEE equipment, should a T/O experience a stuck brake condition on the 9th & 10th car of a 10 car consist, which of the following procedures is the correct method to follow:
Cut out the 1 thru 8 + GS circuit breakers and BCO the affected cars, take the train out of service and have the C/R ride in the last car.
