By now, it is well known that SBCTA is expanding the public transit network in the San Bernardino Valley with implementation of the Redlands Passenger Rail Project, a project that will introduce the Arrow service that will use diesel multiple unit (DMU) rail vehicles. In conjunction with public transit expansion and providing options for the traveling public, SBCTA seeks to reduce greenhouse gas emissions (GHG) and improve air quality. The DMUs purchased for the Arrow service are powered via a diesel engine “generator” providing power to electric motors at the wheels.
SBCTA, however, recognized an opportunity to convert the power generator to an alternative propulsion technology in an effort to produce a zero or low emission multiple unit (ZEMU) that could run on existing rail infrastructure, thus reducing air quality impacts while furthering the use of our existing rail system.
