Weighing of railway vehicles in-motion

The authors briefly review the needs for, and the means of, weighing railway vehicles both statically and in-motion. Increasing emphasis on safety has given greater impetus to ensuring correct tare and gross weights and to ensuring correct loading and weight distribution. The authors' point out the advantages of in-motion weighing enabling, as it does, a cost effective and rapid means of weighing for safety, trade and other purposes. Specific attention is given to a strain gauged in-motion system that has the Internationally recognised OIML approval for weighing at speeds up to 80 km/h and has been tested at 135 km/h.
