What speed must not be exceeded at Medium Speed?

• A. 30 mph
• B. 45 mph
• C. 15 mph
• D. 50 mph

Answer: (A)

Medium speed is the speed limit for a track segment where trains can move faster than yard or restricted speeds but still must stay within a safe maximum to ensure you can stop in time for signals, switches, and other trains. The official limit for this segment is 30 mph, so you must not exceed 30 mph. Exceeding that limit (for example, 45 mph or 50 mph) would violate the medium-speed restriction, while going as low as 15 mph is more typical of yard or restricted-speed areas rather than this medium-speed territory. Staying at or below 30 mph keeps you in the designated safe operating window for this part of the route.
