San Bernardino County Conducts Final Test for Zero Emission Train

The San Bernardino County Transportation Authority (SBCTA) in California added the next generation of clean passenger rail vehicles.

The first self-powered, zero-emission passenger train that will meet Federal Railroad Administration (FRA) regulations began its final testing phase. Service is scheduled to begin this fall between the cities of San Bernardino and Redlands.

The passenger train, a Zero Emission Multiple Unit (ZEMU), uses a hybrid hydrogen and battery technology to propel the train and power onboard electrical systems. Water vapor is the only emission generated from the propulsion system, making this a clean transit alternative.

A Burlington Northern Santa Fe locomotive coupled with ZEMU pulled the new train more than 1,000 miles over two days from Pueblo to San Bernardino in June as part of its testing. In the coming months, ZEMU will complete its testing phase, including trips on the Arrow line and Metrolink system checks. 

“ZEMU’s arrival in San Bernardino is a significant milestone recognizing years of strategic planning for a greener rail system and a commitment to innovative transportation solutions in San Bernardino County,” SBCTA Board President Ray Marquez said in a statement. “I look forward to county residents and visitors riding ZEMU on the Arrow line later this year.”
