The Beltpack™ is a comprehensive, FRA-regulated locomotive control system enabling operators to control driverless locomotives from a safer point of view. The system continually applies the right amount of throttle or brake to maintain the selected speed regardless of the track grade or train mass. It includes a unique safety feature that provides information to the operator through the cab radio, enabling ‘heads up’ operation. Beltpack is designed for railroad operations in the Americas.

  • Consistently maintains the speed selected by the operator
  • Used by FRA-regulated railroad operations
  • Compliant to 49 CFR § 229.15
  • Powered by RemoteIQ™ Rail
  • Provides heads-up operations through cab radio
  • Works with the OCU-III
