Monitoring and Analysis of the Integrated Network (MAIN): Phase II Final Report
Transportation Technology Center, Inc. (TTCI) developed, tested, and implemented a tool to support Interoperable Train Control (ITC)-compliant Positive Train Control (PTC) monitoring and troubleshooting. The tool, called the Monitoring and Analysis of the Integrated Network (MAIN)-Core Data Exchange (CDX), was developed by Railinc under the guidance of TTCI and an advisory group (AG) consisting of Class I railroads, shortline railroads, passenger and commuter railroads, FRA, and ITC-PTC vendors.
MAIN-CDX is a web application, hosted by Railinc, with a user interface providing a standard method of requesting ITC-PTC asset data from other railroads, replying to requests received for asset data, and tracking of request status through a dashboard. The MAIN-CDX application was also integrated with railroad back offices over Interoperable Train Control System Management (ITCSM) messages to support the capabilities of creating data requests and responses through ITCSM messages rather than the user interface.
MAIN-CDX has been well-received by the industry and is being used by railroads running ITC-PTC.
