The Purple Line project, a 16-mile light rail line, recently achieved major milestones. M.C. Dean hosted a customer tour and demonstration of their Pre-Installation Testing and Check-Out (PITCO) at their Modular Mission Critical™ facility to view integrated systems testing and delivered the line’s first train control instrument houses (CIH) and traction power substations (TPSS).
Showcasing PITCO at MMC
M.C. Dean hosted Maryland Transit Solutions (MTS), Purple Line Transit Operators (PLTO), and Maryland Transit Administration’s Program Management Consultant teams, along with other subcontractors, at Modular Mission Critical™ to showcase their PITCO process.
“The entire project was laid out for our customers on a single floor for them to test at this stage of the process,” said Bob Link, vice president of Automation Systems. “Our PITCO process demonstrates a commitment to reducing schedule, cost, and labor risks while meeting our customer requirements.”
Automation Systems, Security & Electronic Systems, Engineering & Construction, and Integrated Infrastructure & Communications Systems teams performed offsite testing and commissioning of Supervisory Control and Data Acquisition (SCADA), security, network management, and communication systems.
Major step in test track construction begins
The Purple Line team recently completed the first four CIH placements for the project.
Each CIH was installed as part of the “test track”, with plans to place 11 more along the 16-mile light rail system. These buildings play a vital role in the processing and control of the train system, generally overseeing movement and preventing collisions.
This team also delivered the fourth TPSS module to the site in December, bringing power to the track. They plan to deliver six more through the end of summer to continue meeting customer timelines and functionality requirements.
