Airbrake6 Flashcards
- ATC is an automatic brake applying apparatus that imposes speed limitations according to:
Cab signal indication
- How many aspects can the ATC aspect display units display on Amtrak locomotives?
4 or 9
- What is the first step to recover from a speed control penalty application?
Place automatic brake valve handle to suppression or lap position
- When operating a P-42 locomotive, what device is cut out if an ATS/IITS failure occurs?
Move ATS pneumatic cut out switch labeled cab signal to out
- On trailing units in a multiple unit consist, what position does the speed control switch on the control stand need to be in?
May be in any position
- What is the indication of an impending penalty when operating in ATS/IITS territory?
Audible alarm sounds and visual indication illuminates
- On a lead locomotive equipped with two control stations, both speed control switches must be placed in what position?
In
- In order to forestall a penalty application when cab signal drops to a more restrictive indication and you are under the speed required, the engineer must do what?
Acknowledge
- What type of train control system requires the engineer to suppress an overspeed condition within a prescribed time limit?
Automatic Train Control (ATC)
- When using the ATC (cab signal) self tester to perform a cab signal test, what must occur when the least restrictive aspect is displayed?
Audible alarm sounds and a penalty application must occur within 8 seconds
- If an ATC failure occurs, what device must be cut out in order to maintain enforced acknowledgement?
Sealed speed control cut out switch
- If the Velocity Zero light remains illuminated when speed is above 12 mph, it is considered a:
Speed control failure
- When must an ATS/IITS wayside signal inductor type warning be acknowledged?
If a block signal indication is less than clear
- When does a train control test need to be performed?
Within 24 hours of initial terminal departure
- On an AEM-7, if you have a speed control failure, what needs to be cut out?
Speed control cut out cock
- What is the cut out procedure if an ATS failure occurs when operating in IITS territory?
Cut out ATS pneumatic cut out switch/cock
- What speed limit is imposed when the cab territory switch is in the out position and ATC is cut in?
79 mph
- According to AMT-3 instructions in table 2, what is the cut out procedure if an ATS failure occurs when operating in IITS territory?
Cut out ATS pneumatic cut out switch/cock
- When would the ATC switch be in the out position?
When operating in non cab signal territory or in cab signal territory during a signal suspension
- What is the name of the display that indicates cab signals?
Aspect Display Unit (ADU)
