6 Questions
What device detects the frequency of the engineer's movements and initiates a penalty brake application if the required movement frequency is not maintained?
Alerter
In the controlling cab, which device displays cab signal aspects?
Automatic Train Control (ATC)
Which system penalizes the engineer if they fail to reduce speed in compliance with cab signal indications?
Automatic Train Stop (ATS)
What is the apparatus used by the RTC to control switches, signals, and traffic direction in CTC territory?
Control Console
Which type of ATC system is primarily found on freight locomotives and enforces speed reduction based on defined braking profiles?
Locomotive Speed Limiter (LSL)
In CTC operations, what method authorizes and governs movements on designated tracks?
Centralized Traffic Control (CTC)
Study Notes
Railroad Safety Systems
- Alerter: a device that monitors the engineer's movement frequency and applies a penalty brake if the required frequency is not maintained or acknowledged.
Display and Control Systems
- Aspect Display Unit (ADU): a device in the controlling cab that displays cab signal aspects.
- Control Console: an apparatus used by the RTC to control switches, signals, and traffic direction in CTC territory, displaying track status and occupancy.
Automatic Train Control Systems
- Automatic Train Control (ATC): a system that applies a penalty brake if the engineer fails to reduce speed according to cab signal indications.
- Automatic Train Stop (ATS): a system that applies a penalty brake if the engineer fails to acknowledge a more restrictive cab signal indication.
- Locomotive Speed Limiter (LSL): a type of ATC system, primarily on freight locomotives, that applies a penalty brake if the engineer fails to reduce speed according to a defined braking profile.
Traffic Control Methods
- Centralized Traffic Control (CTC): a method of operation on designated tracks, where movements are authorized and governed by interlocking signals, cab signals, RTC instructions, or a combination of these.
Test your knowledge on railway signaling systems including devices like ALERTER, ASPECT DISPLAY UNIT (ADU), AUTOMATIC TRAIN CONTROL (ATC) and AUTOMATIC TRAIN STOP (ATS). Learn about how these systems work to enhance safety and control in railway operations.
