The Volumetric Rail Scanner Advantage

A Better Way to Manage Railway Payloads

• What is Volumetric Rail Scanning?

In the last decade, volumetric scanning technology, which is used to determine a payload’s weight by volume, has provided several exciting opportunities for companies spanning the broad spectrum of industry, mining, construction and agriculture. This revolutionary approach to weight data management is a process that your railway application can take advantage of!


Instead of depending on a static traditional scale integrated into the physical rail tracks, a volumetric scanner is able to measure the bulk materials that is loaded into railcars using advanced 3D imaging software. Walz developed this system to be able to automatically capture and record the payload volume of loaded train cars. As the cars slowly travel under the suspended scanner system, which is remarkably simple in its design and implementation, the scanner automatically measures the railcar load, records the results, and can send them directly to an operator. The specialists at Walz are proud to set the industry standard for this new tech, and we’re absolutely confident that it will change the way that your railway operation approaches payload data management.

The Innovative Technology of Volumetric Rail Scanning

Volumetric payload scanning is still a relatively new technology in the industrial, commercial and mining fields. Always striving to innovate, Walz Scale contributed to the pioneering of this weight management technology, and developed our railway volumetric scanner system, which has become the industry standard. You may be wondering, however, how the scanning system works, and is it actually accurate?

The volumetric railcar scanners that we’ve developed are able to measure load volumes in real time, even while the train is in motion. This is achieved by first scanning the empty railcars and then comparing that data to a second scan of the cars once they’ve been loaded. This collected data is used to calculate the car’s load volume with an unprecedented level of accuracy and efficiency.

The Benefits of Adopting a Volumetric Rail Scanning System

You may be curious about how a volumetric scanning system can offer an advantage to your railway application that would make traditional scale systems a less viable option. While there is certainly no denying the practical usefulness of traditional railway scales, which we have no plans to cease production on any time in the near future, more and more volumetric scanning systems are becoming the more feasible alternative. We’ve broken down the biggest benefits that you can expect to reap the rewards of when you take advantage of a volumetric railcar scanning system:

  • Volumetric scanners are able to operate dependably in almost any condition, delivering reliable results.
  • Variables like moisture content, compaction, and uneven railcar loads are non-issues to volumetric scanners. Since these factors don’t affect scanning technology, you will be able to detect and record the most accurate weight by volume possible, surpassing the ability of traditional scales.
  • The speed at which volumetric scanners can record data will lend greatly increased efficiency to your operation.
  • Walz designed our volumetric scanner system to feature extremely user-friendly operation, with an intuitive operating system and user interface. Our system includes features like touch-screen operation, cloud data sharing, and complete smartphone, tablet, PC or laptop connectivity.
  • Walz will only ever manufacture scanner systems that are durable enough to withstand several years of operation without needing regular maintenance, even in the most harsh of environments.
  • Our volumetric load scanning system is a significant money-saver, lowering operating costs and drastically boosting your productivity.
  • 3D imaging technology allows for the accurate recording of every railcar in operation, increasing efficiency and reducing waste.
  • All of our volumetric scanner systems require practically zero maintenance. Should the need ever arise that one of our scanners needs technical attention, Walz is proud to offer onsite service! You’ll never have to worry about maintaining a volumetric scanning system on your own.
  • With volumetric scanning, you can take advantage of 3D imaging capabilities to monitor load distributions, optimize the ways in which your railcars are loaded, and decrease the amount of spillage and waste that occurs.
  • In-motion scanning capabilities mean that the train never has to actually stop for the scanner system to accurately record and transmit data to the system operator — it’s all recorded automatically and quickly!

At Walz Scale, we believe that volumetric scanning is an indispensable tool for railway operations. The ultimate goal of the scanning system is to optimize your payload efficiency, reduce your company costs, and increase your overall production value. 

Is it Really Better to Scan Rail Loads?

With all of this talking up of our volumetric scanning systems, it’s understandable that you may ask “should I even bother with traditional rail scales?” Simply put, the answer to that question lies in what is the best solution for your specific railway application. Walz has an unwavering dedication to providing weight data management systems that exceed all of our customer’s satisfaction levels for both scanners and scales. If a scanner system seems impractical for your railcar setup and you’d rather continue to use a scale system, then the experts at Walz are more than happy to provide you with the best line of portable and permanent railway scales on the market. We’re not just in the business of selling systems, we sell solutions — whichever solution delivers the best results for you.
