If the train operator must cut out brakes in four cars of a ten-car train, what is required?

When brakes are cut out on multiple cars of a train, it signifies a significant safety concern that could affect the train's operation. The need to cut out brakes indicates that those specific cars will not be able to stop effectively, which compromises the overall safety of the train as it operates.

The correct answer underscores the operational protocols dictated by safety regulations. Removing the train from service at the next station ensures that the issue can be addressed properly. This measure prevents the train from continuing to operate in a potentially dangerous condition, where it could encounter situations that require the use of the brakes on those cars.

While an inspection is essential, notifying the control center is also important for operational coordination, but ultimately, the immediate safety imperative is to prevent movement until the issue has been resolved. This action prioritizes safety and compliance with transport regulations, ensuring that all necessary corrective actions can be taken before the train continues its journey.
