In 2001, the Los Angeles County Metropolitan Transportation Authority (LACMTA) began seeking bids for a new order of light rail vehicles for the Gold Line.[3] Four companies submitted proposals; Bombardier, Kinki Sharyo, Siemens, and AnsaldoBreda. Siemens's proposal did not meet LACMTA requirements, and Bombardier declined to bid due to the terms of the contract.[3]
AnsaldoBreda's bid was lower than that of Kinki Sharyo, and as a result, on April 24, 2003, LACMTA awarded a contract to AnsaldoBreda for the production of 50 new light rail vehicles at a cost of $158 million, with options for a further 100 vehicles.[3][4] All trains were to be delivered by 2007.[5]
Bodyshells for the cars were built in Pistoia, Italy, with final assembly in Pittsburg, California.[6] The first vehicles were delivered to Metro in 2005[7] and were first tested on the Blue Line before becoming exclusive to the Gold Line. Trains first entered service in May 2008, significantly behind the contracted schedule.[8] By 2009, delivery of trains was around three years behind schedule, and Metro alleged that trains were at least 5,000 lb (2,300 kg) overweight.[9][10][11] AnsaldoBreda offered to supply Metro with 50 additional trains at a cost of $300 million, with an additional 2 trains as compensation for delivery delays.[10]
Metro decided not to exercise their options to purchase additional P2550 vehicles from AnsaldoBreda,[10][12] and ordered 235 Kinki Sharyo P3010 vehicles in 2012.[13] Following the difficulties of the P2550 procurement process, LACMTA revised its quality control procedures for new rolling stock, and began using best value procurement for future contracts.[14]
Kinki Sharyo is refurbishing the fleet at their Palmdale, California facility, beginning in 2023. Components to be upgraded include doors, safety systems, trucks, and climate control systems.[15][16]
From the beginning of Spring 2023, the P2550 became available to the A Line outside of the former L Line as a result of the completed rail construction and the opening of the Regional Connector.
