Since 1986, Portland’s neighborhoods and outlying communities have come “The Siemens Rail Electrification team has closer together, thanks to TriMet and its MAX Light Rail service. The system, performed tremendously for TriMet on four consisting of six lines and more than 100 miles of track, provides Portland’s light rail extensions since 2004. Siemens has brought industry leading design and installation citizens a safe, comfortable, and reliable commute. Through light rail, TriMet talent to each of our projects which have connects more than just downtown and the suburbs, it connects business, opened on time and under budget. Our most culture, and people with each other. recent project, the 7.4 mile Orange Line extension to Milwaukie, Siemens installed For 30 years, Siemens Mobility has supported TriMet’s mission with rail TriMet’s first Energy Storage Substation, electrification, signaling, and communications. Throughout the relationship, capturing regenerative power from vehicle TriMet and Siemens have worked together to develop a light rail system braking and putting that energy back into unique to Portland and to keep it running on time, efficiently and reliably. the traction powersystem.”

Client Objectives Neil McFarlane When planning the MAX Light Rail system, TriMet envisioned the system General Manager long-term. The initial Blue Line would connect downtown with Gresham in TriMet the east and Hillsboro in the west. Additional lines would extend to other communities. TriMet’s philosophy called for transit to grow alongside Portland’s population and help knit the region together. Success for TriMet would depend, in part, on its infrastructure partners. TriMet was looking for partners that could work with them long-term, tailor solutions to meet the specific needs of the community, and balance innovation with proven technology and budget-friendly solutions. TriMet operates 56 Siemens DC substations and more than 100 track miles of Siemens OCS.

Siemens Solutions • For residential areas, Siemens modernization is to cost-effectively TriMet selected the Mobility division of integrated equipment into a apply 21st century technologies while Siemens Industry to design, produce, more aesthetically pleasing, maintaining equipment that is in and install rail electrification, signaling, TriMet-designed substation good working order and TriMet is and communications systems. Siemens housing, while more cost-efficient comfortable using. brought the right expertise, technology, designs are used in other areas Client Results and stability needed to help TriMet build • Siemens worked with TriMet to Over the course of the 30-year and grow the MAX Light Rail system. develop solutions to shorten relationship between TriMet and Electrification technologies from timelines, when possible, to Siemens, the MAX Light Rail system Siemens power the entire line. They provide traction power ahead has expanded from a single, 15-mile include fifty-six 0.75MW and 1MW, of schedule line to a six-line system with close to 750V DC traction power substations 100 stations serving all corners of • The tie-in of extension lines were and an overhead contact system (OCS) the Portland metropolitan region. scheduled to minimize disruptions spanning 100 miles of track. to existing light rail service With smart electrification technologies, For each project – beginning with the the system has cost-effectively expanded Siemens solutions incorporated Blue Line in 1986 through the Orange to serve more than 130,000 riders ingenuity and innovation to help Line launch in 2015 – Siemens has on an average weekday. It is a light TriMet generate cost savings and worked closely with TriMet to develop rail system that has been truly address challenges. For example, the solutions meeting the specific needs embraced by the local community 2015 Orange Line extension included of the agency and the community it and is one of the most travelled the first use of regenerative energy serves. Some of the ways in which systems in the nation. storage in the United States. Energy solutions have been tailored to meet generated during the braking of Together, Siemens and TriMet have the needs of Portland include: vehicles is converted into electricity created a successful working • The development of modular and then stored to power the next partnership that will help to maintain substations where equipment trains on the line. the popularity of light rail and support is integrated and tested remotely its use well into the future. Presently, Siemens is working with and delivered to the job site as a TriMet on solutions that will extend complete unit, saving time and the life of its infrastructure another money in on-site commissioning 30 years.
