FRA Passenger Equipment Safety Standards 1 — Questions and Answers
Question 1: Under 49 CFR Part 238, what is the minimum static end compression load that Tier I passenger car end frames must be designed to withstand?
- 400,000 lbs
- 600,000 lbs
- 800,000 lbs (Correct answer)
- 1,000,000 lbs
Correct answer: 800,000 lbs
Part 238 requires Tier I passenger car end frames to withstand a minimum static end compression load of 800,000 lbs to protect the occupied volume in a collision.
Question 2: What is the minimum duration that emergency lighting must remain functional on a passenger car following loss of normal power under FRA Part 238?
- 30 minutes
- 60 minutes
- 90 minutes (Correct answer)
- 120 minutes
Correct answer: 90 minutes
FRA Part 238 requires emergency lighting to remain operational for at least 90 minutes after loss of normal power to support safe passenger evacuation.
Question 3: Under 49 CFR Part 238, how must emergency exits on passenger cars be marked?
- Blue reflective markings visible from 10 feet inside the car only
- Yellow markings with instructions printed in English only
- Conspicuously marked to be visible from both inside and outside the car (Correct answer)
- Green exit signs connected exclusively to the normal lighting circuit
Correct answer: Conspicuously marked to be visible from both inside and outside the car
Part 238 requires emergency exits to be conspicuously marked so they can be identified from both inside and outside the passenger car under emergency conditions.
Question 4: What is the primary safety purpose of anti-climbing devices required on FRA-regulated passenger equipment?
- To prevent unauthorized persons from boarding moving trains
- To prevent cars from overriding one another during a collision (Correct answer)
- To stabilize trucks at high operating speeds
- To assist with automatic coupling and uncoupling procedures
Correct answer: To prevent cars from overriding one another during a collision
Anti-climbing devices prevent passenger cars from overriding (riding up on top of) adjacent cars in a collision, preserving the occupied volume and protecting passengers.
Question 5: Under 49 CFR Part 238, which classification describes 'Tier I' passenger equipment?
- Equipment operating at speeds up to 79 mph
- Equipment operating at speeds up to 90 mph
- Equipment operating at speeds up to 125 mph (Correct answer)
- Equipment operating at speeds up to 150 mph
Correct answer: Equipment operating at speeds up to 125 mph
Tier I under Part 238 covers conventional passenger equipment operating at speeds up to 125 mph and must meet the associated structural and safety standards.
Question 6: What does 49 CFR Part 238 require before passenger equipment enters revenue service each day?
- A formal written inspection signed by a licensed mechanical engineer
- A pre-departure inspection to verify key safety systems are functional (Correct answer)
- A complete mechanical overhaul by FRA-certified maintenance staff
- A federal inspector certificate issued for each individual trip
Correct answer: A pre-departure inspection to verify key safety systems are functional
Part 238 mandates a pre-departure inspection of key safety systems each day before passenger equipment carries revenue passengers.
Question 7: Under FRA Part 238, which requirement applies to interior materials used in newly manufactured passenger cars?
- All structural materials must be steel or aluminum alloy
- Interior materials must meet prescribed flammability and smoke emission standards (Correct answer)
- Only seat cushions are required to have fire resistance treatment
- Materials must meet standards individually set by state fire marshals
Correct answer: Interior materials must meet prescribed flammability and smoke emission standards
Part 238 requires all interior materials in passenger cars to meet FRA flammability and smoke emission standards to limit fire spread and protect passengers.
