In October 2013, MassDOT announced plans for a $1.3 billion subway car order for the Orange and Red Lines, which would provide 74 new cars to replace the 1500/1600-series cars, with an option to increase the number to 132 to replace the 1700-series cars.

On October 22, 2014, the MassDOT Board awarded a $567 million contract to build 132 replacement railcars for the Red Line, as well as additional cars for the Orange Line to a China based manufacturer CNR (which became part of CRRC the following year).
CRRC will build the new cars at a new manufacturing plant in Springfield at the site of the former New England Westinghouse Company, with initial deliveries of Red Line cars expected in 2020 (Orange Line deliveries began a year earlier) and all cars in service by 2023.
The Board forwent federal funding to allow the contract to specify the cars be built in Massachusetts, to create a local railcar manufacturing industry.
In conjunction with the new rolling stock, the remainder of the $1.3 billion allocated for the project will pay for testing, signal improvements and expanded maintenance facilities, as well as other related expenses.
Sixty percent of the car's components are sourced from the United States.
The new cars will hold 15 additional passengers, will have four wheelchair parking areas per car, and will be equipped with on-board video surveillance.
The cars will have wider doors to allow faster boarding at busy stations, and can allow wheelchair access even if one of a pair of door panels fails to open.
The MBTA has rebuilt Track 61 to serve as a test track for the new Red Line cars.

In December 2016, the MBTA opted to purchase additional identical cars from CRRC, allowing replacement rather than costly refurbishment of the 01800 series cars.
The second order is for 120 cars costing $277 million, with an option for 14 additional cars.
Combined, the 2014 and 2016 orders will provide a single common fleet for the entire Red Line by 2023, with enough cars to eventually run 3-minute headways at peak.
Replacement of the signal system is expected to be complete by 2021 on the Red Line; the total cost is $218 million for both the Red and Orange Lines.
Some of these new cars have been delivered, and are now being tested as of August 12, 2020.
