If the headlight on the leading end of a train fails en route and the locomotive has two working auxiliary lights, the train may:

• A. Continue unrestricted to the next point where headlight can be repaired.
• B. Stop and wait for repairs.
• C. Proceed at reduced speed to the next signal.
• D. Proceed with a flagman signaling.

Answer: (A)

If the headlight on the leading end fails but there are two working auxiliary lights, you can continue to the next point where the headlight can be repaired without reducing speed. The two auxiliary lights provide sufficient forward visibility and signaling, so normal operation is permitted until you reach a location where repairs can be made. You’d choose stopping, reduced speed, or signaling with a flagman only when those auxiliary lights aren’t available or other safety rules require them.
