PTS Knowledge 3 — Questions and Answers
Question 1: What is 'restricted speed' in railroad operations?
- A speed not exceeding 25 mph while prepared to stop within half the range of vision (Correct answer)
- A speed limit posted at a highway grade crossing
- A maximum speed set by the FRA for freight trains
- The speed used when approaching a red signal
Correct answer: A speed not exceeding 25 mph while prepared to stop within half the range of vision
Restricted speed means operating no faster than 25 mph while being prepared to stop within half the range of vision, short of a train, switch, or obstruction.
Question 2: What is the purpose of a job briefing in track safety?
- To assign disciplinary points for past infractions
- To ensure all workers understand the hazards and protection methods before starting work (Correct answer)
- To record attendance for payroll purposes
- To notify the dispatcher of the work crew's location
Correct answer: To ensure all workers understand the hazards and protection methods before starting work
A job briefing ensures every worker knows the specific hazards, protective measures, and emergency procedures before work begins.
Question 3: What does 'train approach warning' provide to workers on or near the track?
- It triggers automatic brake application on approaching trains
- It gives workers advance notice that a train is approaching so they can move to safety (Correct answer)
- It activates signal lights along the right-of-way
- It alerts the train crew to slow down
Correct answer: It gives workers advance notice that a train is approaching so they can move to safety
Train approach warning gives track workers sufficient advance notice of an approaching train so they can reach a place of safety in time.
Question 4: Under PTS rules, what must happen before removing blue flag protection from equipment?
- The supervisor must call the dispatcher for approval
- All workers who applied the protection must confirm they are clear (Correct answer)
- A two-hour waiting period must elapse
- The nearest track foreman must sign a clearance form
Correct answer: All workers who applied the protection must confirm they are clear
Blue flag protection may only be removed by or with the authorization of the same workers who applied it, once they are all clear of the equipment.
Question 5: What is the significance of a 'positive stop' requirement in PTS?
- All workers must stop walking when a train passes
- Equipment must be capable of stopping before a specific point, not just slowing down (Correct answer)
- Workers must physically plant both feet before giving signals
- Trains must halt at every work zone regardless of protection in place
Correct answer: Equipment must be capable of stopping before a specific point, not just slowing down
A positive stop requirement means equipment must be able to stop before a defined point, ensuring a definitive margin of safety rather than just reduced speed.
Question 6: What is an 'absolute block' in railroad safety?
- A section of track where only one train is allowed at a time, regardless of signals (Correct answer)
- A block signal that cannot be passed under any circumstances
- A physical concrete barrier placed across a track
- A federally mandated no-entry zone around a derailment site
Correct answer: A section of track where only one train is allowed at a time, regardless of signals
An absolute block is a section of track protected so that only one train may occupy it at a time, providing the highest level of occupancy protection.
Question 7: Which of the following is a key characteristic of high-visibility safety apparel required for railroad workers?
- It must be dark-colored to prevent sun glare
- It must meet ANSI/ISEA standards for retroreflective and fluorescent material (Correct answer)
- It must include the employer's logo for identification
- It must be waterproof regardless of weather conditions
Correct answer: It must meet ANSI/ISEA standards for retroreflective and fluorescent material
FRA regulations require high-visibility apparel to meet ANSI/ISEA 107 standards, which specify fluorescent and retroreflective material performance.
