What is the role of the Dispatcher related to delays in train service?

The role of the Dispatcher in relation to delays in train service is primarily to be notified of any known delays. This is crucial because the Dispatcher's responsibilities include ensuring the safe and efficient operation of train services. Being informed about delays allows the Dispatcher to make necessary adjustments to scheduling, reroute trains if needed, and communicate pertinent information to train crews and relevant personnel. This awareness helps maintain safety, efficiency, and service reliability across the entire rail network. The other options involve functions that are outside the specific scope of the Dispatcher's responsibilities concerning delays—for example, controlling train speeds or inspecting train conditions in real-time, which are typically the responsibilities of the train crews and onboard operations staff.
