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

• A. Traffic Control
• B. Track Control
• C. Time Control
• D. Track Warrant

Answer: (A)

Traffic Control is the term that describes the system or authority responsible for regulating train movements within a defined area, usually under a dispatcher or centralized control. It covers how signals are set, routes are protected, and train movements are coordinated to prevent conflicts and ensure safety. The other options don’t fit because a track warrant is a separate written authorization method, not what TC expands to; Time Control isn’t a standard signaling term; and Track Control isn’t the established expansion of this acronym in railroad signaling. So, Traffic Control is the best fit.
