Locomotive Remote Control System

Accuspeed™ is a comprehensive locomotive speed control system that enables operators to safely control the locomotive via a wireless remote control. The system continually applies the right amount of throttle or brake to maintain the selected speed regardless of track grade or train mass while the operator focuses on train movements, track conditions and personal safety. 

Highlights
Consistently maintains the speed selected by the operator
Used by a majority of Class I railroads in North America
OCU-III controller offers a wide variety of options
Compliant to 49 CFR 229.15
OCU-III

Feature-rich controller that includes an embedded GNSS location, a patented method for pushing OCU positional data to the RCL system, bluetooth link to the internal archive record and a Wi-Fi port to accommodate future expansion

Dynamic Speed Control

Cattron's patented speed control system streamlines the complexities of throttle and brake manipulation to maintain the selected speed regardless of track grade or train mass

Internal Archive Record
