Operator TriMet relies on rail technology from Siemens for newly opened light rail line

14.09.2015
  • MAX Orange Line between Portland and Milwaukie
  • 18 light rail vehicles S70 type energy
  • Energy storage system type Sitras SES
  • Signaling and communication system

Today, TriMet's new MAX Orange Line, a light rail project between Portland and Milwaukie (USA), was officially inaugurated. Siemens advanced rail technologies are now operating on the Orange line including its S70 light rail vehicles designed and manufactured at Siemens Sacramento, California plant to move riders along the system, rail signaling and communication systems to help manage train operation, and the company's first Sitras SES energy storage unit in the U.S. that uses regenerative braking to sustainably power the line.


The 7.3-mile (around 12 Kilometer) MAX Orange Line is the region's sixth construction project of the development project Metropolitan Area Express (MAX) to expand the city's transport network to cope with the expected population growth in the Portland area. The line will improve transit in the corridor that extends from the terminus of the MAX Green and Yellow lines at Portland State University in Downtown Portland to Milwaukie and North Clackamas County.

"Siemens is proud to be a technology partner for Trimet for more than 30 years, starting in the this project is a perfect example of how advanced rail technologies can help to revitalize city centers, creating jobs and stimulating economic development", said Jochen Eickholt, CEO Siemens Mobility Division.

The newly redesigned light rail vehicles were built based on input from TriMet and riders, featuring new seating arrangements, additional wheelchair accessibility, larger windows and improved HVAC systems that automatically adjust based on the number of people in the vehicle.

The vehicles also include better sight lines for the driver, more ergonomically designed main cabins, and larger displays for train operators so they are better able to monitor the vehicle's status to improve safety and efficiency. Maintenance enhancements were made based on TriMet's feedback including rearrangement of systems to increase accessibility to key components on the vehicles and improved diagnostic systems.

The innovative regenerative rail energy storage technology allows for energy created during braking to be stored and then re-used in one of two forms, energy savings or voltage stabilization during peak demand times. TriMet will utilize the system in voltage stabilization mode. In this mode, the storage unit allows the system to avoid problems disruptions that can occur in mass transit operations if power drops below a certain level.

If a number of vehicles accelerate simultaneously, system voltage can drop below a critical level and result in instances of under-voltage tripping in vehicles and, consequently, lead to disruptions in passenger service. The Sitras SES ensures the system voltage always remains within the required range and voltage-related disruptions no longer occur.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
