Coupled-In-Motion (CIM) Rail Scales

Keep the train moving while weighing


Safe, Accurate and Reliable In-Motion Weighing

Eliminate the costs and hazards of uncoupling and positioning each car for weighing by weighing in-motion. METTLER TOLEDO's Coupled In-Motion Rail Scale facilitates safe and accurate weighing of an entire train at speeds up to 10 km/hour (6 mph) to get goods to their destination faster.

VRS241 Rail Scale

Reliable Weighing for Static or In-Motion Rail Cars

No matter how demanding your application is, METTLER TOLEDO has a railroad track scale to handle the job. VRS241 scales are available for static weighing or coupled in-motion weighing. Choose between two deck options: a concrete deck with manholes and a steel deck with removable plates. Both provide easy access to the load cell network. VRS241 scales are designed to handle the massive loads applied by rail traffic. They are built to last, with the strongest structural components fully supporting the rails. METTLER TOLEDO scales are designed to weigh rail cars safely, accurately, and reliably.

  • Static Weighing

The static version of the VRS241 scale weighs uncoupled rail cars that are stopped on the scale. A typical installation consists of two weighbridges that are spaced to provide single-draft weighing for various lengths of rail cars.

The coupled in-motion (CIM) version of  the scale weighs rail cars that are coupled together and moving across the scale at 3 to 5 miles per hour. It makes weighing quicker and safer by eliminating the need to uncouple rail cars and position them on a static scale.

7260 Railroad Scales

For Weighing Coupled, In-Motion Rail Cars

7260 rail scales provide accurate weighing of rail cars. Coupled, in-motion scales are designed for weighing rail cars that are coupled together and moving across the scale at 3 to 5 miles per hour. The weighbridge converts a section of railroad track into a scale. Weighbridge is designed to meet AREMA requirements for Cooper E-80 loading. POWERCELL load cells transmit a powerful signal for accurate, reliable weighing.

IND9R86 Coupled In-Motion Rail Car Scale Controller

Weigh Coupled In-Motion Railcar Trains in Just Minutes Safely, Reliably and Accurately
Model IND9R86 scale controllers weigh coupled railroad cars while a train is in motion, eliminating the costs and hazards of uncoupling and positioning each car for weighing.

Train entering scaleThe IND9R86 dynamic weighing controller, integrated with a METTLER TOLEDO dynamic rail scale, allows for automated weighing of entire trains as they cross the scale at speeds up to 10 km/hour (6 mph). Individual railcar weights are obtained without uncoupling of cars, and train total weights are calculated. Railcar identification information from an RFID tag is integrated into the weighing record. The controller stores and prints weight information for any length train, even those exceeding several hundred cars, and provides data storage for hundreds of trains.

The system includes an industrial PC with Windows® XP, 240 x 64 graphical display or LCD monitor, rail wheel detector interface, scale terminal for MTX® Powercell or Analog scale connection, and interface to local printer. Optional interfaces to PLC protocols, such as EtherNet/IP™, ControlNet™, Profibus®, and AB RIO™, are available. The IND9R86 CIM controller is designed to meet or exceed NIST HB-44 and OIML requirements.
  • Unattended Operation — Allows for automatic weighing and data capture; no operator is required
  • Attended Mode — User-friendly Windows® interface allows the operator to weigh trains, enter car information and print train reports using a standard keyboard and mouse commands
  • Weigh Statically or Dynamically — Allows for both unattended dynamic weighing and attended static weighing with the same system, providing for extra user flexibility
  • AEI Railcard RFID Tag Interface — System automatically includes railcard AEI tag data in the weight record
  • Powerful Database Storage and Communication — Hundreds of trains can be stored in MS Access® database or other OLEDB/ODBC compatible database types, either locally or remotely on a networked computer.  For remote facilities, either a wireless, fiber optic, or phone line connection can be used for data communication
  • Integration with Plant MES or MRP Systems – Available communication formats include TCP/IP, serial, and PLC fieldbus (EtherNet/IP™, Allen Bradley RIO, ControlNet™, Device-Net™, Profibus®)
  • Rollback Detection and Recovery – Allows for accurate and complete train weighing even if the train reverses direction, such as in load out operations
  • Remote monitoring and system control – Allows for alerting train operators via portable radio or warning lights of conditions such as train over-speed or railcar overweight, plus provides ability to place system in weighing mode via a portable radio or other input device
  • Expanded Diagnostics – When used with METTLER TOLEDO DigiTOL® load cells, the IND9R86 finds potential trouble all the way down to the load cell level, allowing you to take corrective action before a problem occurs
  • New or Retrofit – The IND9R86 can be used in new installations or as part of a retrofit project using either a METTLER TOLEDO or other brand weighbridge and load cells
  • Certified to NTEP HB44 – Allows for use in legal-for-trade applications
