When must the headlight on a train be displayed?

The headlight on a train must be displayed brightly both during the day and at night to ensure safety and visibility. The primary function of the headlight is to make the train more conspicuous to others on or near the tracks, including other trains, maintenance personnel, and any individuals who might inadvertently approach the railway. Having the headlight on at all times also helps alert pedestrians and vehicles at crossings, significantly reducing the risk of accidents.

In daylight, while the illumination may not be as visually apparent, the use of the headlight ensures constant visibility. This standard promotes a safe operating environment by reinforcing the train's presence regardless of the time of day. Therefore, the requirement for the headlight to be brightly displayed at all times aligns with best safety practices in railroad operations.
