How does visibility change during adverse weather conditions?

Visibility generally decreases during adverse weather conditions such as rain, fog, snow, or heavy winds. These factors can obscure the view of signals, tracks, and other important visual indicators necessary for safe train operation. Reduced visibility can lead to difficulties in spotting obstacles or signals, increasing the potential for accidents and making it crucial for locomotive engineers to exercise heightened caution.

In adverse weather, it becomes essential for engineers to rely more on instruments and signals, often requiring reduced speeds and increased stopping distances. Understanding how visibility diminishes under these circumstances is key for maintaining safety and operational integrity during challenging weather scenarios.
