What should be done according to the CBTC TOD when approaching a wayside signal?

When approaching a wayside signal, the appropriate action is to proceed according to the CBTC (Communication-Based Train Control) Train Operating Doctrine (TOD). This means that the train engineer should adhere to the specific instructions and protocols outlined in the CBTC system's operational guidelines.

The TOD is designed to enhance safety and efficiency in train operations by providing real-time communication and signal data. It helps ensure that trains operate at safe speeds and follow signal indications correctly, which is crucial for preventing collisions and maintaining safe distances between trains.

By proceeding according to the CBTC TOD, the train engineer is utilizing the technology's guidance to make informed decisions based on the current signal system status, thereby ensuring safety and compliance with operational standards. This reflects the need for a detailed understanding of how to interact with signals and follow established procedures that are central to the CBTC system's effectiveness.
