Rail weighbridge
A rail weighbridge is used to weigh rolling stock including railroad cars, goods wagons and locomotives, empty or loaded. When loaded, the net weight of the cargo is the gross weight less the tare weight when known. These are calibrated using scale test cars, which are often old freight cars rebuilt to have a very precise and exact weight. It is also used to weigh trams.
