For cost effective management of rolling stock and rail wagons, the DRW train weighing system is easy to install in the existing rail. The DRW consists of sensors drilled directly into the rail which sense weight and train direction.

Accuracy of the system depends on the condition of the rail, ballast (or concrete base), in ideal installations 0.5% per train and 1% per wagon can be achieved.

With a choice of controllers which allows the unit to be configured for simple axle weighing application to complete train scales with loading manifests.
