What actions should a train engineer avoid while switching in CBTC yards?

Operating in Release mode without conditions met is the correct action that a train engineer should avoid while switching in CBTC (Communication-Based Train Control) yards. Release mode allows a train to operate beyond its normal limits, but it should only be engaged when certain predefined conditions are satisfied. If these conditions are not met, it can lead to unsafe situations including potential collisions or other accidents, as the train’s movements may not be strictly controlled or monitored.

In CBTC yards, following the specified speed limits, communicating with the control center, and checking for proper signals are crucial actions that enhance safety and operational efficiency. Adhering to speed limits helps to ensure that trains can stop safely and respond to signals without exceeding safe operational thresholds. Communicating with the control center is essential for coordinating operations and responding to instructions. Checking for proper signals ensures that the engineer is aware of the current track conditions and can safely navigate the yard. Each of these actions aligns with the safety protocols that the engineers must adhere to, while engaging in safe and efficient switching operations.
