• A. 5 mph
• B. 20 mph
• C. 10 mph
• D. 15 mph

Answer: (C)

Speed control in a yard is essential because yard tracks have tighter curves, more switches, and workers and equipment nearby. A low, clear limit helps you see signals, observe switch positions, and stop quickly if something unexpected happens. The typical limit used for moving into a sorting yard is 10 mph, which provides enough control for precise handling of switches and alignment while maintaining safety. Going faster would raise the risk of missing signals or derailing on switches, while going much slower would hinder operations; 20 mph is too fast for yard conditions, and 15 mph or 5 mph are outside the standard yard limit used in most practice scenarios.
