What does the Terminal Proceed signal indicate?

The Terminal Proceed signal indicates that the train is allowed to proceed without restrictions. This means that the locomotive engineer can continue on the track without any limitations or conditions to observe. In practice, this type of signal ensures that the route ahead is clear and safe for travel, allowing for an uninterrupted movement of the train.

Understanding the context of this signal is crucial for locomotive operations, as it directly impacts safety and efficiency. When a Terminal Proceed signal is displayed, the engineer can trust the preceding signals and the track conditions, providing confidence in maintaining the schedule and operational flow.

Choices that suggest stopping, needing permission, or reducing speed reflect scenarios where caution must be exercised or conditions are not favorable for normal travel, which is not applicable under the Terminal Proceed indication.
