Bridge Stress Committee

The Bridge Stress Committee was appointed in 1923 by the UK Department of Scientific and Industrial Research under Sir Alfred Ewing, to investigate stresses in railway-bridges, especially as regards the effects of moving loads.

Driving wheel

On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive).

Duplex locomotive

A duplex locomotive is a steam locomotive that divides the driving force on its wheels by using two pairs of cylinders rigidly mounted to a single locomotive frame; it is not an articulated locomotive.
