On tracks other than main or signaled tracks, what is the maximum speed unless otherwise specified?

• A. 10 MPH
• B. 15 MPH
• C. 25 MPH
• D. 35 MPH

Answer: (A)

On tracks that aren’t main or signaled, the safest default speed is 10 mph. This low speed gives you better control and enough time to react to unexpected conditions, such as switches, crossing points, or workers on or near the track. The rule includes “unless otherwise specified,” meaning a posted sign or dispatcher instruction can override this default if a higher speed is permitted for that segment. The other speeds listed would be unsafe on un-signaled, non-main tracks because there’s less protection and visibility, making it harder to stop in time or avoid hazards.
