Why might a conductor need to adapt their operations on a curved track?

Adapting operations on a curved track is critical for ensuring the safety and stability of the train. When a train travels on a curve, centrifugal forces act on it, which can lead to potential derailment or instability if the train is not operated at appropriate speeds. Conductors must adjust their operations to maintain a safe and controlled speed that accommodates the curve's radius and the train's weight distribution. This adjustment is vital for preventing excessive lateral forces that could compromise the train's integrity or comfort for passengers.

While other options touch on important aspects of rail operations, they do not specifically address the immediate requirements and safety protocols needed when navigating curved tracks, making them less relevant in this context.
