As with any vehicle, it is important to ensure that trains do not exceed axel limits, or gross rail load limits. Using a rail scale, or weighing freight during loading using a floor or forklift scale, can help to ensure that rail cars are not overloaded. This is important to ensure proper weight distribution in order to prevent track damage, ensure efficient braking, and to reduce the risk of derailments.
Providing accurate weight information is often a regulatory requirement. Gathering, storing and analyzing weight data can be achieved by using sophisticated weigh indicators that link with back office systems. This set up can ensure that rail operators comply with safety regulations, as well as providing an audit trail.
