The Regional Transportation District of Denver began off-site bench testing of train and traffic signals for at-grade crossings on the FasTracks I-225 Rail “R” Line. The bench testing process uses computer software to simulate trains approaching intersections and crossings.
“Testing train and traffic signal equipment allows us to make critical adjustments to operations and timing so that everything functions properly before being installed in the field. It’s more cost effective, safer to the public and easier to conduct this initial testing in a controlled environment where multiple signal controllers can be wired in one location without being subjected to live automobile and train traffic,” RTD Traffic Engineer Brett Higgins said.
After bench testing is completed, RTD will initiate systems integrated testing, which tests real trains and traffic equipment at crossings and intersections prior to opening the line.
