PTS Basic 5 — Questions and Answers
Question 1: What rule governs the minimum warning time a lookout must provide to roadway workers before a train arrives at the work location?
- Sufficient time for all workers to clear the track and reach a place of safety, at minimum 15 seconds (Correct answer)
- At least 60 seconds in all situations regardless of train speed
- 30 seconds for freight trains and 45 seconds for passenger trains
- 10 seconds, which is considered adequate for experienced workers
Correct answer: Sufficient time for all workers to clear the track and reach a place of safety, at minimum 15 seconds
The warning must allow every worker to stop their activity, move clear of the track, and be at a place of safety with at least 15 seconds remaining before the train arrives.
Question 2: Which factor most directly affects the stopping distance of a freight train traveling at 60 mph?
- Track grade and train tonnage, which can require a mile or more to stop (Correct answer)
- The engineer's reaction time, typically 2-3 seconds
- The type of rail (jointed vs. continuous welded)
- Weather conditions such as rain or fog
Correct answer: Track grade and train tonnage, which can require a mile or more to stop
A heavy freight train at 60 mph may require well over a mile to stop due to the enormous momentum from its tonnage and grade effects, which is why roadway workers cannot rely on trains stopping for them.
Question 3: Under what circumstances may a roadway worker act as both a RWIC and a flagger simultaneously?
- Never — the roles require separate individuals to be effective (Correct answer)
- Only when the crew has fewer than three workers
- When working within 1,000 feet of a controlled signal
- Only on branch lines with speeds below 25 mph
Correct answer: Never — the roles require separate individuals to be effective
The RWIC must coordinate overall protection and supervise the crew while the flagger must maintain an uninterrupted watch for trains — combining these roles compromises both functions and is not permitted.
Question 4: What is required before on-track roadway maintenance equipment (hi-rail vehicles, tampers, etc.) can travel from one work zone to another?
- The operator must obtain movement authority or confirmation from the RWIC for the route to be traveled (Correct answer)
- The equipment must be escorted by a locomotive
- A supervisor must physically inspect the route ahead
- The dispatcher must issue a formal track warrant for each move
Correct answer: The operator must obtain movement authority or confirmation from the RWIC for the route to be traveled
On-track equipment moving between work zones must have confirmed movement authority covering the route, as the equipment itself is subject to the same on-track protection requirements as workers on foot.
Question 5: A roadway worker new to a work site must receive a job briefing:
- Before fouling the track, even if work has already begun for the rest of the crew (Correct answer)
- Only at the start of each shift, not upon arrival mid-shift
- Within the first 30 minutes of joining the crew on track
- Only if the new worker will be performing a task different from the rest of the crew
Correct answer: Before fouling the track, even if work has already begun for the rest of the crew
Any worker joining a job in progress must receive a complete job briefing before fouling the track, because a late arrival has not been informed of the protection type, limits, or hazards.
Question 6: What does 'inaccessible territory' mean in the context of roadway worker protection?
- Track territory where trains cannot enter due to physical or dispatcher-controlled barriers, providing the highest level of protection (Correct answer)
- A work zone that has been declared unsafe and closed to all personnel
- Territory where communication equipment does not function reliably
- Track sections reserved exclusively for maintenance-of-way equipment
Correct answer: Track territory where trains cannot enter due to physical or dispatcher-controlled barriers, providing the highest level of protection
Inaccessible territory is track that trains physically cannot reach or that has been locked out of dispatcher control, offering roadway workers absolute protection because train entry is impossible.
Question 7: Which of the following scenarios represents an improper use of on-track protection procedures?
- A worker fouling the track before the RWIC has confirmed protection is in effect, relying on their own assessment that no train is due (Correct answer)
- A flagger using a two-way radio to relay a train approach warning to the RWIC
- The RWIC obtaining authority before the crew arrives at the job site
- Workers clearing to 25 feet when a train passes through the work zone
Correct answer: A worker fouling the track before the RWIC has confirmed protection is in effect, relying on their own assessment that no train is due
Fouling the track before confirmed protection is in effect — even if the worker believes a train is not coming — bypasses the formal safety system and violates FRA roadway worker protection requirements.
