Development
Shortly after the groundbreaking of the Purple Line Extension in 2014, procurement started for new trains to run on it. The base order consists of 64 cars, 34 for the Purple Line Extension Phase 1, and 30 to replace the first order A650s (cars 501-530) with DC motors, which would have been retired in 2021, although this has not occurred. In 2014 there were 4 option orders totaling to 218 cars; 112 cars for general expansion, 20 cars for Purple Line Extension Phase 2, 12 for Phase 3, and the remaining 74 to replace the second order of A650s (cars 531-604) with AC motors (to have been retired in 2030).[5] The base order was to be delivered from 2019 to 2021, with the options from 2021 to 2030. CRRC was chosen as the manufacturer in 2017.[6] At that point, they had expected a Spring 2020 first delivery with completion in 2021. To accommodate this order, yard expansion work started in 2019. As of January 2022, it is scheduled for completion in 2023.[7]
Design
The exterior design shows influence from the Kinki Sharyo P3010s found on the light rail lines with yellow sides and full-color LED destination signs, compared to the green monochrome dot-matrix LED signs used with the A650s. Internally, it features more longitudinal seating than its predecessors[3] to increase capacity (although early renders depicted against such[4]).
