PTS Positions of Safety 4 — Questions and Answers
Question 1: A track geometry car is approaching at high speed. How does this differ from a freight train in terms of position of safety requirements?
- No difference — all movements require the same position of safety
- Geometry cars have smaller profiles so reduced clearance is acceptable
- High-speed movements reduce warning time, requiring earlier and more distant clearing (Correct answer)
- Only a supervisor may authorize workers to foul a track for high-speed movements
Correct answer: High-speed movements reduce warning time, requiring earlier and more distant clearing
High-speed movements dramatically reduce the time between detection and arrival, so workers must clear to a position of safety earlier and farther from the track.
Question 2: What should a worker do if they are unsure whether a position they have selected qualifies as a position of safety?
- Treat it as unsafe and seek a confirmed, designated position before the next train movement (Correct answer)
- Estimate the clearance by pacing steps from the nearest rail
- Ask the passing train crew for confirmation
- Use the position once and report the uncertainty after the train passes
Correct answer: Treat it as unsafe and seek a confirmed, designated position before the next train movement
When in doubt, a worker must assume the position is unsafe and find a confirmed position of safety — uncertainty should never be resolved by assuming safety.
Question 3: How does the presence of wide loads or shifting cargo on a passing train affect where a worker should stand?
- Workers should increase their distance from the track beyond the standard minimum (Correct answer)
- Wide loads travel slower, so the standard minimum is sufficient
- Only flagmen need to account for wide loads; track workers are trained to avoid them
- Wide loads are marked, so workers can return to standard distance when no markings are seen
Correct answer: Workers should increase their distance from the track beyond the standard minimum
Wide or shifted loads may extend beyond the normal car clearance envelope, so workers should maintain additional distance when such loads are known or possible.
Question 4: During a tunnel work site, workers are completing track repairs. A train is authorized to enter. What is the primary challenge to reaching a position of safety in a tunnel?
- Limited physical space for worker clearance due to tunnel walls (Correct answer)
- Poor radio reception preventing dispatcher communication
- No natural light to identify positions of safety
- Tunnel air pressure changes that disorient workers
Correct answer: Limited physical space for worker clearance due to tunnel walls
Tunnels severely restrict available clearance space, making it essential that designated niches or alcoves are identified as positions of safety before work begins.
Question 5: Which of the following is NOT an acceptable position of safety during live track operations?
- A designated alcove in a tunnel wall
- The shoulder of an adjacent road embankment beyond the fouling area
- The center of a parallel track that currently has no scheduled trains (Correct answer)
- A fenced equipment staging area outside the right-of-way fence
Correct answer: The center of a parallel track that currently has no scheduled trains
An adjacent track without scheduled trains is not a position of safety because unscheduled movements can occur and the fouling area of that track still exists.
Question 6: A worker's tool falls onto the track as a train approaches and they are already in the position of safety. What is the correct action?
- Remain in the position of safety and retrieve the tool after the train passes (Correct answer)
- Quickly retrieve the tool before the train arrives if it is safe to do so
- Signal the train to stop before retrieving the tool
- Inform the lookout, who will retrieve the tool for the worker
Correct answer: Remain in the position of safety and retrieve the tool after the train passes
Once in a position of safety, a worker must stay there until the train has fully passed — no tool or equipment is worth re-entering the fouling area.
Question 7: What is the role of a point protection lookout in relation to a worker's position of safety?
- To observe approaching trains and give workers adequate warning time to reach safety (Correct answer)
- To stand in the position of safety as a marker for other workers
- To physically escort each worker to the designated position of safety
- To stop train traffic while workers move between positions
Correct answer: To observe approaching trains and give workers adequate warning time to reach safety
A point protection lookout's duty is to observe for approaching trains and provide timely warnings so workers can reach the identified position of safety before the train arrives.
