What is the name of the fixed signal that illuminates green with the sound of a bell going off at a terminal?

The fixed signal that illuminates green with the sound of a bell going off at a terminal is indeed known as the train starting signal. This signal is critical for train operations, especially at terminals, as it indicates to the train crew that it is safe to begin their journey. The combination of the green light and the audible bell provides a clear and unmistakable indication that all systems are clear and that the train can proceed safely.

In a terminal setting, this signal ensures that trains leave in an orderly fashion and that any necessary checks or balances have been accounted for prior to departure. It plays a vital role in maintaining safety and efficiency in train operations. Other terms like departure signal or clearance signal may seem related, but they do not specifically describe the signal paired with an audible alert at the exact moment the train is ready to start its journey. Understanding these nuances in signaling is essential for effective train operation.
