s. Originally, they were used by brakemen to travel from car to car to apply hand-operated brakes. With the adoption of the air brake this practice was abandoned. However the running board was still used as an observation point to pass hand signals to the train driver (train engineer in North America) when cars were being shunted (switched in North America). The increased use of radio communication made this unnecessary. Today, most countries forbid anyone to be atop a moving freight car.

Automobile

In the early 20th century, all automobiles were equipped with running boards. The necessity of using them was caused by the fact that first cars were designed with a narrow, high body bolted to the

. Most roads were unpaved and tall narrow wheels and tires were needed to get through the ruts, mud, and snow. A running board served as a step to a vehicle's cabin, and sometimes could be wide enough to serve as a place to sit or even lie down for an adult. During the 1920s and 1930s, car design was evolving rapidly to become more sleek and aerodynamic, which largely eliminated the need for running boards. The first automobile designed without running boards was the 1929 Ruxton, and the first by a high production manufacturer was the 1936 Cord. The Cord changed the attitude towards running boards for many years ahead. Common materials for running boards include aluminum, fiberglass, stainless steel and ABS plastic.
