Train Driver Crew Communication and Protocols 2 — Questions and Answers
Question 1: When a dispatcher issues a 'Form D' track authority, what does this document authorize?
- The train to occupy a specified segment of main track between defined limits (Correct answer)
- Emergency speed restrictions due to track damage
- A crew to perform maintenance on a specified section of track
- A passenger train to make an unscheduled stop
Correct answer: The train to occupy a specified segment of main track between defined limits
A Form D (or equivalent track warrant) is a written or transmitted authority granting a train the right to occupy a defined segment of track.
Question 2: What does 'crew resource management' (CRM) training emphasize for train crews?
- Effective communication, situational awareness, and assertiveness to prevent errors (Correct answer)
- Efficient fuel management and schedule adherence
- Physical fitness standards for operating railroad equipment
- Proper completion of paperwork and compliance logs
Correct answer: Effective communication, situational awareness, and assertiveness to prevent errors
CRM training focuses on teamwork skills: communicating clearly, maintaining awareness of the operating environment, and speaking up when something is wrong.
Question 3: What is 'direct train control' (DTC) and how does it differ from CTC?
- DTC uses radio instructions from a dispatcher instead of wayside signals; CTC uses remote-controlled signals (Correct answer)
- DTC is an onboard computer system; CTC is a wayside signal system
- DTC is used in yards only; CTC is for mainline operations
- DTC requires a second engineer; CTC allows solo operation
Correct answer: DTC uses radio instructions from a dispatcher instead of wayside signals; CTC uses remote-controlled signals
In DTC territory, a dispatcher grants verbal or written authority by radio or phone with no wayside signals, while CTC uses remotely controlled signals to authorize movements.
Question 4: What is the correct response when a train driver receives conflicting instructions from the dispatcher and the signal system?
- Comply with the more restrictive indication and immediately clarify the discrepancy with the dispatcher (Correct answer)
- Follow the dispatcher's verbal instruction, which overrides signals
- Stop the train and wait for written authority before proceeding
- Follow the signal indication and report the conflict at the terminal
Correct answer: Comply with the more restrictive indication and immediately clarify the discrepancy with the dispatcher
Always obey the most restrictive indication and immediately contact the dispatcher to resolve the conflict before proceeding.
Question 5: What does a 'slow order' (temporary speed restriction) require of the engineer?
- Reduce speed to the specified limit throughout the restricted zone and not exceed it until clear (Correct answer)
- Apply brakes smoothly and return to normal speed as quickly as possible
- Reduce speed only if track conditions are visibly poor
- Contact the dispatcher for permission to exceed the slow order speed
Correct answer: Reduce speed to the specified limit throughout the restricted zone and not exceed it until clear
A slow order mandates operating at or below the specified speed from the beginning to the end of the restricted zone, no exceptions.
Question 6: What is the purpose of the 'cab-to-cab' radio channel on a multi-unit locomotive consist?
- To allow communication between the lead and remote (distributed power) locomotive units (Correct answer)
- To enable the engineer to talk directly with the conductor in the last car
- To provide a backup channel to the dispatcher when the main radio fails
- To transmit cab signal data to the rear locomotive unit
Correct answer: To allow communication between the lead and remote (distributed power) locomotive units
The cab-to-cab channel enables voice communication between the lead locomotive operator and crew members at remote locomotive units in distributed power operations.
