What does the abbreviation COT stand for in railroad signaling terminology?

• A. Current of Traffic - Track Signaled in One Direction
• B. Track Warrant Control
• C. Traffic Control
• D. Main Track Yard Limits Signaled

Answer: (A)

The main idea is that COT identifies how a track is signaled in terms of direction. It stands for Current of Traffic, indicating that the track is signaled for movement in one direction only. The full phrase “Current of Traffic - Track Signaled in One Direction” matches how crews understand a unidirectional signaling setup on that track, helping prevent conflicting movements and ensuring trains proceed only in the allowed direction. The other options refer to different concepts—Track Warrant Control is a separate authorization method, Traffic Control is a broad term, and Main Track Yard Limits Signaled describes a different signaling scenario and isn’t the specific abbreviation.
