What immediate action is required as your train passes an Approach signal?

• A. Increase speed to 60 mph
• B. Maintain current speed
• C. Reduce speed to 30 mph and call it out
• D. Stop immediately

Answer: (C)

Approach signals warn that the next signal may require stopping, so you must immediately begin slowing to the designated approach speed to ensure you can stop if needed and to have time to observe and comply with the next signal. In this context, the prescribed approach speed is 30 mph, and you should call it out to your crew or dispatcher to confirm awareness and coordinate actions. Increasing speed would violate the signal's warning, and maintaining your current speed ignores the need to prepare for the next signal. Stopping immediately is not required unless the next signal explicitly requires a stop. Reducing to the approach speed and announcing your approach is the correct, safety-focused action.
