Which statement about Authorized Train Speeds is NOT true?

Which statement about Authorized Train Speeds is NOT true?

• A. They must not be exceeded.
• B. They must be observed even if wayside signs are not properly displayed.
• C. They may be exceeded when the crew deems it safe.
• D. They apply to all trains on the track.

Answer: (C)

Authorized Train Speeds are the maximum speeds permitted for a specific track segment, chosen to keep trains within safe stopping distances and account for track geometry and conditions. You must not exceed these speeds because they are enforceable limits designed to protect against derailments and excessive wear, regardless of the situation. Even if wayside signs aren’t properly displayed, you still follow the authorized speed as the governing limit, using timetable and rules as the backup guidance. The limit applies to all trains on that track, without giving crews the option to override it based on personal judgment. That’s why the statement claiming you may exceed the speed if the crew thinks it’s safe isn’t true.
