Western-Cullen-Hayes Type SF utilizes the weight of the car itself to compensate for greater-than normal speeds. It can fit rail from 4 to 7 inch high and there are no loose parts. Each SF contains 360 lb of steel that are effective in stopping cars, not just wheels, the company says. The cushion plus friction absorbs shock in the wheel stop, not in the center-pin of car. Type SF uses engineering principles in a practical way to stop cars.
