How does a 'service brake' differ from an 'emergency brake'?

The distinction between a 'service brake' and an 'emergency brake' lies primarily in their respective functions and applications during railway operations. The service brake is designed for regular use, enabling the train to decelerate and come to a stop under normal operating conditions. This brake system is employed during routine stops at stations or to manage speed while traveling, ensuring safe and controlled braking in everyday scenarios.

In contrast, the emergency brake is activated in situations where there is an immediate need to stop, such as when a hazard is detected or in the event of a potential derailment. The emergency brake is a backup system designed to provide maximum stopping force under critical circumstances.

Understanding the function of the service brake as a standard operational tool highlights its role in maintaining safe and efficient train operations. This knowledge is essential for train operators and safety personnel to ensure they can effectively manage both regular and emergency stopping procedures.
