You are operating a single locomotive through a receiving yard and you are operating at restricted speed. What speed should not be exceeded?

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

Answer: (C)

Restricted speed means you must be able to stop within the distance you can clearly see ahead, taking into account track conditions and braking. In a receiving yard, where there are switches, workers, and equipment on adjacent tracks, you need a speed that lets you react and stop for any signal or obstacle. About 10 mph is the practical limit that supports stopping in time while still allowing efficient yard movement. Going faster than that (20 mph or even 15 mph) risks not being able to stop for a switch, a worker, or an unexpected obstruction. Moving at 5 mph would be unusually slow for typical yard operations unless conditions require it.
