Siemens P2000
[3] In July 1992, the Los Angeles County Transportation Commission issued a request for proposals for light rail vehicles for use on the then-under construction Green Line.[5] Siemens-Duewag opened a manufacturing facility in Carson, operated in partnership with AAI Corporation, to build the car shells.The car shells, the key structural components of the train, were the first to be manufactured in the United States for 50 years.[8] Introduction into service was delayed slightly, drawing criticism from the news media that highlighted the P2000 contract's high cost and Metro's contemporary fiscal issues.In June 2013, Metro awarded a fixed price contract to PAMCO Machine Works in Monrovia, California, to overhaul the powered axle assemblies for the then thirteen year old P2000 trains.
