PTS PTS - Personal Track Safety Safe Access and Egress 4 — Questions and Answers
Question 1: Under PTS rules, a worker may only access the track cess without formal track authority when:
- They are wearing full PPE and high-visibility vest
- The cess is outside the designated safe clearance distance from the running line (Correct answer)
- No trains have passed in the previous hour
- They have verbal approval from any team member
Correct answer: The cess is outside the designated safe clearance distance from the running line
The cess can only be used without track authority if it is confirmed to be outside the minimum safe clearance distance specified for that line.
Question 2: A worker is required to cross multiple lines to reach their work location. Which sequence is correct?
- Cross all lines simultaneously as quickly as possible
- Obtain authority for each line crossing individually and verify safety before each step (Correct answer)
- Cross with a colleague so one can watch for trains
- Cross only after verbally confirming with another worker that it is safe
Correct answer: Obtain authority for each line crossing individually and verify safety before each step
Each line crossing must be covered by specific authority and the safety of each track must be independently verified before crossing.
Question 3: What is the purpose of the 'four-foot' in the context of track access and egress?
- A measurement tool for rail spacing
- The space between the two running rails, which is a restricted zone requiring authority to enter (Correct answer)
- A buffer zone marked four feet from the rail head
- The minimum distance a worker must stand from a moving train
Correct answer: The space between the two running rails, which is a restricted zone requiring authority to enter
The four-foot is the space between the rails and is considered the most hazardous zone; formal authority is required before entering it.
Question 4: A work group has authority to access a track section from 08:00 to 12:00. At 11:55, some tasks remain incomplete. The correct action is to:
- Continue working until the task is done since they are almost finished
- Request an extension of the authority before it expires, then continue only if granted (Correct answer)
- Work until 12:15 since a 15-minute grace period applies
- Have one member work while another watches for trains
Correct answer: Request an extension of the authority before it expires, then continue only if granted
Working beyond the authorized time without a formal extension is a serious violation; the extension must be obtained and confirmed before continuing.
Question 5: During a PTS briefing, the controller states there is a 15-minute engineering possession. Which factor most directly determines the safe working time available to workers?
- The 15-minute window minus travel time to and from the work site within that possession (Correct answer)
- The total possession duration regardless of travel distance
- The time remaining after the first train passes through
- The number of workers available on the shift
Correct answer: The 15-minute window minus travel time to and from the work site within that possession
Workers must account for travel time to and from the worksite within the possession window, leaving the remaining time as actual safe working time.
Question 6: If a worker realizes mid-task that their planned egress route has become blocked, what is the immediate required action?
- Continue working and use any available route when the time comes
- Immediately inform the person in charge and identify an alternative safe egress route (Correct answer)
- Signal for a train stop using a red flag
- Walk along the track to find the nearest access gate
Correct answer: Immediately inform the person in charge and identify an alternative safe egress route
A blocked egress route is a safety-critical situation that must be reported immediately so an alternative route can be identified and authorized before work continues.
Question 7: When stepping over a running rail during authorized track access, a worker should:
- Step on the rail head for better grip
- Step over the rail with a high-clearance step to avoid tripping on the rail head or foot (Correct answer)
- Kick the rail with their boot to test stability
- Slide their foot along the rail to detect any obstructions
Correct answer: Step over the rail with a high-clearance step to avoid tripping on the rail head or foot
Stepping high and clear over the rail head prevents tripping, which could leave a worker stranded in a dangerous position.
