Weighwell’s In-Motion Train Weighing System is designed specifically for the rail freight industry, delivering accurate load data without interrupting train movements. By weighing at low speed, operators can monitor compliance with weight load limits, identify uneven distribution and address potential safety issues before trains leave the site.

Using a single Portable Train Weigher (PTW) unit, the in-motion rail scale is quick to install, easy to relocate and ideal for freight terminals, material handling sites or other loading locations. Installation can be completed in as little as 15 minutes, with no permanent track modifications required.

Quick, portable in-motion train weighing setup

The in-motion weighing system can weigh trains at speeds of up to 3mph (5kph), with an achievable accuracy of 2–3% (or better, subject to site conditions). It supports axle loads of up to 40,000kg (20,000kg per wheel), making it suitable for heavy freight applications. The PTW is compatible with a wide range of track gauges and rail profiles, with installation requiring no cutting, drilling or welding, avoiding costly civil works or permanent alterations.

Benefits of portable in-motion train weighing

  • Improved Safety – Detect overloads and poor load balance to reduce derailment risk.
  • Quick to Install – At only 556mm in length, the Heavy-Duty PTW unit fits between rail fastenings and requires no permanent track modifications.
  • Flexible Operation – Deploy the system wherever it’s needed from main terminals to remote sidings.
  • Real-Time Data – Access immediate, actionable data by viewing the weighing results on either a digital indicator or software (laptop) interface.

Key Applications

  • Rail freight terminals
  • Intermodal ports
  • Aggregate and quarry operations
  • Recycling centres
  • Mines
  • Bulk material handling facilities
