Coupled-In-Motion: Dynamic Railcar Weighing
New technology offers an enhanced weighing solution for accurate and reliable weighing of coupled railcars in motion.
The IND9R86 rail scale controller is used to weigh rail cars as they cross a scale at speeds up to 10 kilometers per hour. The controller automatically detects individual railcars and provides transaction reports both for individual railcars and for the entire train. Interface to inductive wheel detectors and Automatic Equipment Identification readers is provided. Compared to traditional static weighing, benefits include enhanced productivity, increased safety and fully unattended operation.
Powerful data storage and communication provides the ability to store hundreds of train reports in Access or SQL database formats, allowing for simple export via Ethernet, fiber optic, modem or wireless connection.

Pseudo Single Draft (PSD) technology
Single draft weighing is the ideal method for capturing railcar weights, especially for liquid cargoes where slight end-to-end weight shifts may compromise accuracy. In the real world, however, cars come in varying lengths, making true Coupled In-Motion single draft weighing impossible to achieve.
PSD offers the solution: weighments for each bogie taken independently on two scale platforms spaced so that, regardless of car length, there is the least possible time gap between the car’s two weight sampling periods. In addition to providing legal-for-trade accuracy that rivals true single draft weighing, this method employs a straightforward and cost-effective installation using only two small scale platforms.

Industries and Applications
CIM weighing offers important benefits:
- Increased safety because cars don’t have to be decoupled
- Speed and efficiency maximizes use of equipment and reduces interruptions to traffic
- Accuracy of measurement
- Meet OIML, MID and NTEP requirements
- Legal for trade and commercial transactions
These advantages of dynamic railcar weighing are particularly significant both for high-value materials, and for high volume/long train materials:
- Oil
- Liquefied Natural Gas (LNG)
- Coal
- Iron Ore
- Plastics
- Aggregates
