A demonstration of Siemens' eHighway systems Siemens AG

Siemens plans to build a trolley-like system near the ports of Long Beach and L.A. that will power shipping trucks with overhead electrical lines, the company announced Wednesday.

The one-mile stretch of “catenary” infrastructure will be installed on the northbound and southbound sections of Alameda Street where it intersects with Sepulveda Boulevard in Carson, Calif.

The up to four trucks at a time will be able to use the overhead lines or disconnect and drive with hybrid diesel, compressed natural gas, battery or other on-board energy source.

The South Coast Air Quality Management District signed a contract with Siemens to test the company’s eHighway system. The one-year-demo is slated to begin in July 2015.

”This project will help us evaluate the feasibility of a zero-emission cargo movement system using overhead catenaries,” said Barry Wallerstein, SCAQMD’s executive officer. “Southern California’s air pollution is so severe that it needs, among other strategies, zero- and near-zero emission goods movement technologies to achieve clean air standards.”
