train surfing

Train surfing refers to the dangerous and illegal act of riding on the exterior of a moving train or subway car. It involves individuals clinging onto the sides or roofs of trains, often without any safety equipment, and often in an attempt to perform stunts or gain a thrill-seeking experience. Train surfing is extremely hazardous and can result in serious injury or death due to the high speeds, electrical risks, and the confined spaces within which the practice takes place.
