Trains have three lights at the front, which serve specific purposes for safety and visibility:
– White Headlight: The central white headlight on a train illuminates the track ahead, helping the train crew spot any obstacles, signals, or potential hazards on the tracks during nighttime or low visibility conditions.
– Red Light: As mentioned earlier, the red light at the rear of the train is a safety signal indicating to others that they should not approach or pass the train from behind.
– Classification Lights: Some trains are equipped with a pair of lights on either side of the headlight, known as classification lights. These lights have specific colors and configurations that communicate information to railway personnel and other trains regarding the train’s identity, status, and direction.
