This project reflects the Metra Automated Communications and Onboard Reporting Network (ACORN) that includes the vehicle based technology to track train movement, report a train's adherence to the schedule, make onboard and platform announcements, perform automatic passenger counting, send digital information to onboard and platform signs, and communicate operational changes and alerts to customers. Project will also install a new communication network with a complete replacement of all hardware, including computers, GPS units, modems, and other components that are no longer supported or past their useful life or capacity. There is a pilot in progress for evaluation in 2020 with a longer–term deployment plan to be established.
