Overview

The QuEST Rail Digital Signal Processor – Style C Track Circuit (DSP-C) is designed specifically for freight and transit rail applications.

The DSP-C is a digital version of the classic AC/DC Style C track circuit with excellent analytics and remote alarm capabilities via RS422 allowing railroads to monitor track circuit performance, so issues such as poor ballast conditions and leaky Insulated Joints (IJs) can be corrected before operations suffer.
