What must the train engineer do in MATC mode when making an employee pick-up?

When making an employee pick-up in MATC (Multiple Automatic Train Control) mode, the train engineer is required to transition to MCS (Manual Control System) mode. This is necessary because MCS mode allows for manual control of the train, which is essential during operations like employee pick-ups, where precise movements and the ability to react to changing situations are critical. In MCS mode, the engineer can safely manage the train's speed and make necessary adjustments as required for picking up employees, ensuring safety and compliance with operational protocols.

Operating in MATC mode would not provide the control needed for such specific and potentially hazardous circumstances. Additionally, during an employee pick-up, there may not be a requirement to notify passengers or request permission from the conductor as part of the operational protocol, making MCS mode the appropriate choice for this task.
