What are the functions of auxiliary lights on a train?

Auxiliary lights on a train serve specific purposes to enhance safety and functionality. Their primary role includes improving visibility for both train operators and those in proximity to the train, especially at public highway crossings. By illuminating areas where trains cross roads, these lights help ensure that drivers and pedestrians are aware of the train's presence, thereby reducing the likelihood of collisions or accidents at these critical intersections.

While auxiliary lights can contribute to indicating the presence of the train, signaling emergencies, or illuminating the train's path at night, the focus on visibility at public highway crossings underscores a key safety measure put in place to protect individuals in those specific locations. The emphasis is on fostering awareness in high-traffic areas where the risk of an incident might be heightened. This specialized function makes the lights particularly valuable in contexts where clear visibility can prevent potentially dangerous situations.
