AnsaldoBreda P2550

The P2550 is an articulated high-floor electric light rail vehicle manufactured by AnsaldoBreda for the Los Angeles County Metropolitan Transportation Authority's Metro Rail system.

Background
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. 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. 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. All trains were to be delivered by 2007.

Construction
Bodyshells for the cars were built in Pistoia, Italy, with final assembly in Pittsburg, California. The first vehicles were delivered to Metro in 2005 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.

By 2009, delivery of trains was around three years behind schedule, and Metro alleged that trains were at least 5000 lb overweight. 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. Metro decided not to exercise their options to purchase additional trains, subsequently ordering 235 Kinki Sharyo P3010 trains in 2012.

Service history
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.

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.
