What happens when the control cut-out circuit breaker is in the 'OFF' position?

When the control cut-out circuit breaker is positioned in the 'OFF' state, it interrupts the electrical circuit that supplies power to the traction motors, resulting in the train having no power to propel itself. This means that the propulsion system is effectively disabled, preventing the train from moving forward or backward.

In this context, the energy supplied by the traction motors is crucial for the operation of the train, and by cutting off power, the circuit breaker ensures that there is no unintended movement or operation. It is a safety measure that allows for maintenance or emergency situations where the train should not be in operation. Understanding this function is essential for ensuring safe operations and proper handling of the train's systems.
