In Non-Signaled TWC yard limits with no signals, what speed must the train proceed?

• A. Restricted
• B. Approach
• C. Normal
• D. Stop

Answer: (A)

In non-signaled yard limits, there are no signals to govern your speed, so you must proceed at restricted speed. This means you operate at the slowest safe speed, prepared to stop within the distance you can see ahead, and you must be able to stop for any obstruction, misaligned switch, or other train or worker in the yard. The yard environment—lots of equipment, tracks, and limited visibility—makes it essential to assume you can’t stop quickly if something appears suddenly. Normal track speed isn’t safe here because there’s no signaling to guarantee you can stop in time.
