What speed cannot be exceeded when operating in a yard?

• A. 10 mph
• B. 25 mph
• C. 5 mph
• D. 15 mph

Answer: (A)

In yard operations, speeds are kept low to allow precise control and to protect workers and equipment around switches and cars. The commonly prescribed maximum in a yard is 10 mph. This limit provides enough momentum to move cut trains efficiently while still giving the engineer time to react to switching movements, signals, or anyone on or near the tracks. You must not exceed the posted yard limit, and if a specific area has a lower requirement (for example near switches or workers), that tighter limit applies as well. The other speeds listed—25 mph or 15 mph—are not safe or appropriate for yard environments, and 5 mph, while appearing in some restricted zones, is not the general yard limit.
