Trains using a non signaled siding, operating at restricted speed must not exceed what speed?

• A. 15 mph
• B. 25 mph
• C. 5 mph
• D. 30 mph

Answer: (B)

Restricted speed means you must be able to stop within the distance you can see ahead, given current conditions. On a non-signaled siding there are no signals to govern your movement, so you have to assume you could encounter an opposing train, an occupancy, or an obstruction at any point ahead. To maintain a safe stopping margin in that scenario, the maximum is 25 mph. Going faster could leave you with insufficient distance to stop safely, while slower speeds aren’t necessary for this setup and aren’t required by the rule.
