What should you never do on or near a railroad track?

Stopping on or near a railroad track is extremely hazardous due to the potential for an approaching train that may be difficult to hear or see until it's too late. Train tracks are designed for trains, and any stationary vehicle or individual can be at significant risk of being struck if they are obstructing the tracks. Stopping in the area of the tracks can also impede emergency services and disrupt the flow of rail traffic. It's essential to maintain a safe distance from the tracks to avoid any accidents, as trains often move faster than anticipated, and their stopping distances are considerably longer than those of vehicles.

Parking, running, and walking in the vicinity of railroad tracks carry their own risks but do not inherently carry the same immediate danger as stopping does. Parking, for example, can involve remaining stationary for a longer period, potentially leading to a dangerous situation if the vehicle obstructs the tracks. Therefore, while all actions near railroad tracks require caution, stopping is particularly critical to avoid serious accidents.
