Although a footplate was almost universal in British locomotive design, and often in continental European locomotives, it was never a common feature of steam locomotives constructed in North America, and disappeared from Russian locomotives and big-power locomotives in British colonies (or former colonies), Australia and New Zealand during the 20th century. On those locomotives, the boiler and cab were mounted directly on the frame,2 and the walkway around the boiler – "running board" or "foot board" – was not a structural element.
The footplate has openings cut in it for various purposes. The firebox always extends beneath the footplate. The cylinders are beneath the footplate, and steam pipes pass through holes to them. The reversing gear control for the valve gear also passes through, and in some locomotives part of the valve motion also extends through the footplate.

On British Railways Standard Locomotives the running plate/board was high enough to clear the wheels; on earlier British locomotives, the tops of driving wheels usually projected through slots in it and were covered by "splashers" – analogous to mudguards on a road vehicle.
