KB Signaling Showcases QuEST™ Rail Software-Based LCP at Railway Interchange 2025

Written by Carolina Worrell, Senior Editor
KB Signaling Inc., a Knorr-Bremse subsidiary based in Grain Valley, Mo., on May 20 highlighted the QuEST™ Rail Soft Local Control Panel (sQLCP) at Railway Interchange 2025, marking the debut of the first third-party application developed through the KB Signaling Certified Developer Program.

Built to run on the KB Signaling™ Wayside System Data Management Module™ (WSDMM) edge computing platform, the sQLCP app “transforms legacy, hardware-based local control panels (LCP) into a modern, software-based solution —offering railroads new operational flexibility without the cost or complexity of additional equipment,” according to the company.

The QuEST sQLCP app includes full LCP functionality, “enabling maintainers to request control, execute commands, and receive indications from interlockings via a familiar interface—now delivered through a WSDMM device already installed at thousands of sites across North America.” The sQLCP, KB Signaling says, is designed for “seamless integration” with the KB Signaling™ ElectroLogIXS® platform using the Genisys® protocol over ethernet.

Configurable via QuEST Rail’s free QLCP-NET Developer Tool, the app allows users to create or update control panel designs offline and deploy them remotely through WSDMM’s web user interface (Web GUI). Future versions, the company says, will enable additional data overlays—such as track temperature from the KB Signaling™ Rail TempEst™ app and wayside signal diagnostics—to enhance situational awareness and reduce fieldwork, and support of additional protocols. The result, KB Signaling notes, “is a more agile approach to control, testing, and maintenance that maintains full compatibility with industry standards.”

“Our customers are looking for dependable, streamlined ways to upgrade operations without adding footprint or complexity,” said KB Signaling Managing Director Jeff Baker. “With the QuEST Rail sQLCP app, we’re providing a direct path to smarter control—fully digital, easily configurable, and backed by the reliability of the WSDMM platform. It’s the kind of value our Certified Developer Program is built to deliver.”
