What is required when operating the train in MATC mode with yellow flags/lamps?

When operating the train in MATC (Multiple-Area Train Control) mode with yellow flags or lamps, it is essential to take manual control of the train and comply with flagging procedures. This step ensures that the train operator is fully aware of the situation and can navigate safely through areas where there may be restrictions or operational changes indicated by the flags or lamps.

In MATC mode, yellow flags or lamps typically signify that the train must be operated with caution due to potential hazards or specific instructions from railway personnel. By taking manual control, the conductor can immediately adjust the train's speed and handling as necessary to ensure safety, following the procedures indicated by the flags. This conformity to flagging instructions is critical for ensuring both the safety of the passengers and the integrity of the rail operations.

Hence, this option emphasizes the importance of active and cautious operation in accordance with the safety protocols established in railway operations.
