What is the signal series in Tunnel A?

The signal series in Tunnel A being referenced as the 100 even series is significant for understanding the signaling system used within that specific tunnel. Each signal series corresponds to a range of signals that convey important operational information to the train engineers regarding speed, track conditions, and other vital instructions needed for safe and efficient train operation.

The 100 even series is designated for Tunnel A, which allows engineers to quickly recognize the relevant signals while operating in that area. This series helps streamline communication and ensures that train operators are alert to the specific regulations and procedures relevant to the tunnels they are traversing.

Understanding these signal series is crucial for safety compliance, as they directly impact the way trains are managed in different sections of the PATH system. Recognizing the 100 even series for Tunnel A aids engineers in maintaining the expected protocols, thereby minimizing risks associated with signal misinterpretation.
