The InterTest® Automated Interlocking Test System provides for fully automated tests for all types of railway interlockings – from the oldest relay-based systems to the newest microprocessor-based systems. InterTest® completely automates the performance of both in-service and two-year interlocking tests, and it makes testing more accurate, thorough, consistent, reliable and cost-efficient. Specialized Hardware Tools – InterTest® includes a combination of permanently installed and portable hardware componentry. UTE’s proprietary Control Point Interfaces (CPIs) and CPI routers are installed at all control points throughout the interlocking to provide the foundation of the system. VHF radio modems, client computers and a host computer are then added as needed.
Fully Automated Testing – InterTest® creates a detailed computerized model of the track and signal system layout for any specific interlocking. It then automatically manipulates the interlocking into the desired state and measures the status of every object in the interlocking test limits – including all signals, track circuits, switches and non-vital indications – throughout every step of the test.
Based on Your Existing Test Procedures – InterTest® does not evaluate, analyze or diagnose the vital logic of an interlocking, and it doesn’t dictate how to test interlockings. It simply automates your existing test procedures and recreates them in a computerized test template.
