CBTC Testing on an Operating Railroad/Transit System: Challenges Faced

This paper describes how many operating railroads and transit agencies are in the process of implementing Communications Based Train Control (CBTC) into their existing configuration, or as a replacement to an existing signal system. Although the majority of the Verification and Validation (V&V) of such new technology systems is performed within a simulated environment, it is not possible to comprehensively cover all test scenarios, field configurations, interfaces to the existing system, and nuances of existing operating rules, prior to implementing the system on-site. The field environment provides the vital final phase for completing the testing requirements and proving the system in its operating configuration. The planning of field testing for CBTC systems requires consideration of a number of factors, logistics, scheduling, operating environment, avoidance of disruptions, concurrent safe testing sessions alongside revenue service, which forces the field test organization to take on a more comprehensive systems approach. This paper discusses the challenges faced during testing of CBTC systems based on the experience gained by agencies and suppliers and presents approaches to overcome them with the help of sound test planning and some innovative methods.
