The HR4000 is a rapid transit railcar being built by CRRC Massachusetts in Springfield, MA for the Los Angeles Metro Rail heavy rail lines. A total of 64 cars are being built as part of the base order, primarily for initial section of the Purple Line Extension, with 5 (contradictory information exists about this) options that total 218 cars, 282 cars total, intended to replace the Breda A650 as well as for overall expansion and to accommodate the later parts of the extension.[2][3][4]
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 2030).[4] 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.[5] 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.[6]
The design was first unveiled in July 2021.[7][8]
A June 2022 document has shown that 112-car general expansion option from 2014 was split into a smaller 84-car option in the same category. Of the 28 cars cut from this option, 24 cars were moved new option for increasing train lengths and/or frequency on the Red line, and the remaining 4 were moved to Purple Line Extension Phase 3. As of said document, the first two cars (referred to as Married Pair, or MP3, set 4005-4006) are scheduled to arrive in Los Angeles in August 2022, with sets MP1 and MP2 scheduled to arrive in December, with 4 sets being in production, and 10 sets with carbodies in varying stages of construction. Retirement of the original A650s is currently scheduled for 2028.
In October 2022, it was reported LA Metro had cancelled the HR4000 contract. It is not clear if the HR4000s will be delivered. In November, it was revealed a new model known as the HR5000 was under development.
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 roll signs originally used on the P865 and P2020 (they were later replaced with full color LEDs), green monochrome LED found on the current A650 with somewhat poor contrast, yellow monochrome LED on the P2550, or square-matrix LCD on the P2000. On the inside, it feature more longitudinal seating than their predecessors[2] to increase capacity (although early renders depicted against such[3]). Reception to the change was mixed. Scrolling LED dot-matrix displays are on the width. On the sides, LCD displays are found. It is likely to be the first modern metro car in the continental United States[a] with open gangways[b], but this could be beaten by the CQ400s for the Metropolitan Atlanta Rapid Transit Authority or the R211T being delivered for the New York City Subway. USB ports are also to be available and maps that light up, although this is poorly shown in renders.
Notes
- ^ Open gangway trains will exist in Hawaii on the Honolulu Rail Transit opening in 2023, likely before the HR4000 enters service.
- ^ Some articulated trains did have open gangways in the first half 20th century, namely the D-type Triplex that ran in the New York City Subway from 1925 to 1965 and the original 5000-series built for the Chicago L running from 1947 to 1985.
