1. What does this sign mean? → Train level crossing up ahead; slow down, watch for trains, and be ready to stop.
2. What is a 'shoving movement' and what special precaution is required? → Moving a car or train in reverse with a crew member protecting the leading end
3. What is a 'thermal sun kink' and when is it most likely to occur? → A lateral track buckle caused by rail expansion in high heat, most common in summer
4. What is the FRA's purpose for the Confidential Close Call Reporting System (C3RS)? → To allow employees to report near-miss incidents without fear of discipline
5. The Driver's Safety Device (vigilance/dead-man's system) activates because you did not respond. What does it do? → Applies the brakes automatically to stop the train
6. What is the main reason for a speed restriction over points (switches) at a junction? → To allow safe negotiation of the diverging route
