What operational mode must the engineer switch to after stopping in MATC?

After stopping in MATC (Manual Automatic Train Control), the engineer must switch to MCS mode, which stands for Manual Control Station mode. This mode allows the engineer to take manual control of the train and is necessary for safe operations, especially when transitioning from an automatic to a manual operation environment.

MCS mode enables the engineer to directly manage train actions such as acceleration, braking, and adherence to signals in situations where automatic control is not applicable, ensuring that they can respond quickly to any changes in the operational environment. This switch is crucial for maintaining safety protocols and ensuring that the train operates according to the set standards after a stop in MATC.

In contrast, the other operational modes serve different functions or are not appropriate in this context. Release mode would not be suitable immediately after stopping, as it is used to disengage systems. Manual mode is a general term that does not specify the necessary functions required in MATC scenarios. Automatic mode would also not be applicable since the purpose of stopping in MATC is to transition back to manual operations.
