Abstract
A running board for railway car features a plank and a support where the support is constructed of a steel that is thicker than the steel of the plank. The support features flanges with mounting holes by which it is mounted to the railway car. As a result, the lives of the mounting areas of the support match the life of the plank so that the life of the running board is extended. The plank features side vertical and horizontal lip portions that extend from opposite side edges of the plank's anti-slip walkway. The horizontal lip portions are engaged by tabs formed in the support so that the plank is securely held to the support.
