Must authorized train speed be observed even if wayside signs are not displayed?

• A. Yes
• B. No
• C. Only for passenger trains
• D. Only during daylight

Answer: (A)

Authorized train speed is set by the timetable, track authority, and operating rules, not by whether wayside signs are visible. This means you must operate at the speed that is permitted for that track segment, even if no speed-reducing or other signs are displayed. Signs convey restrictions, but they do not grant new permissions or override the established limit. If signs are missing or unreadable, you rely on the timetable and dispatcher instructions to determine the maximum safe speed and proceed accordingly, always adhering to the most restrictive applicable limit and any signals along the route. If in doubt, proceed at a conservative speed and verify with the dispatcher. The other options don’t fit because speed limits apply to all trains and at all times, not only during daylight, and you don’t get to ignore authorized speeds when signs aren’t shown, nor do those limits apply only to passenger trains.
