PTS PTS - Personal Track Safety Sentinel Scheme and Fitness 4 — Questions and Answers
Question 1: Which fitness requirement is specifically relevant to PTS workers who may need to identify signal aspects or warning lights?
- Adequate color vision to correctly distinguish railway signal colors (Correct answer)
- 20/20 uncorrected visual acuity in both eyes
- Night vision rating above the standard civilian threshold
- Peripheral vision exceeding 180 degrees in each eye
Correct answer: Adequate color vision to correctly distinguish railway signal colors
PTS workers must meet color vision standards because correctly identifying signal colors and warning lights is critical to personal safety on or near the track.
Question 2: A track worker is prescribed medication that may cause drowsiness or impaired concentration. What should they do before their next track shift?
- Consult their doctor or occupational health professional and inform their employer before working on track (Correct answer)
- Take half the prescribed dose on working days only
- Restrict themselves to daylight-hours shifts for additional safety
- Take no action if they personally feel alert and capable
Correct answer: Consult their doctor or occupational health professional and inform their employer before working on track
Any medication that could impair alertness or reaction time must be discussed with a medical professional before working in a safety-critical railway environment.
Question 3: What is the significance of assessing a track worker's physical fitness and mobility during a PTS medical?
- To confirm the worker can safely move on and off the track and react quickly to emergencies (Correct answer)
- To determine the correct size of PPE to be issued
- To fulfill a legal requirement under the Equality Act 2010
- Physical fitness has no formal role in PTS fitness assessments
Correct answer: To confirm the worker can safely move on and off the track and react quickly to emergencies
Track workers must be physically capable of moving clear of approaching trains quickly and safely, making mobility and physical fitness a genuine safety requirement.
Question 4: At what point during a shift may a PTS worker be required to undergo a drug and alcohol test?
- At any time — before, during, or after the shift (Correct answer)
- Only at the very start of the shift before accessing track
- Only if they visually appear impaired to a supervisor
- Only when returning from a break exceeding two hours
Correct answer: At any time — before, during, or after the shift
Drug and alcohol testing can be conducted at any point — pre-shift, random during the shift, or post-incident — under Network Rail's testing policy.
Question 5: What is Network Rail's general policy regarding alcohol consumption for workers prior to and during track access?
- Workers must not be under the influence of alcohol and must comply with strictly enforced breath alcohol limits (Correct answer)
- Alcohol is permitted in moderation as long as the worker personally feels fit for work
- Workers may consume alcohol the evening before with no restrictions as long as they sleep it off
- Alcohol restrictions apply only to workers operating powered equipment, not foot-patrol workers
Correct answer: Workers must not be under the influence of alcohol and must comply with strictly enforced breath alcohol limits
Network Rail enforces strict, near-zero alcohol limits for all safety-critical workers including those with PTS, with breath tests used to verify compliance.
Question 6: A track worker is newly diagnosed with epilepsy. What is the most likely outcome for their PTS certification?
- Their PTS competency will be suspended pending medical assessment and documented management of the condition (Correct answer)
- They may continue working provided their medication controls seizures and they feel well
- Epilepsy cannot affect PTS certification due to protections under disability law
- They are automatically granted a medical waiver after six consecutive seizure-free months
Correct answer: Their PTS competency will be suspended pending medical assessment and documented management of the condition
Epilepsy poses a serious risk in a trackside environment, so PTS certification is typically suspended until occupational health confirms the condition is appropriately managed and controlled.
Question 7: Which of the following conditions would most likely render a track worker temporarily unfit for PTS duties?
- Taking prescribed medication confirmed to cause dizziness or significantly impaired concentration (Correct answer)
- Having a non-communicable skin condition that does not affect mobility or awareness
- Being color-blind in a way that does not affect recognition of railway signal colors
- Having a fully healed fracture with confirmed complete recovery
Correct answer: Taking prescribed medication confirmed to cause dizziness or significantly impaired concentration
Any condition or medication impairing alertness, balance, or reaction time creates an unacceptable safety risk for track workers and requires medical clearance before returning to duty.
