R142 (New York City Subway car)

880 of the R142s are numbered 6301–7180, and the remaining 150 cars are numbered 1101–1250.

There are two types of cars: "A" (cab at one end) and "B" (no cabs). "A" cars are powered with four traction motors each, with the passenger doors opposite each other. The "B" cars are powered by two traction motors at the number-two end, and the passenger doors are staggered (car ends are numbered on the lower body just above the truck).[4][5] The trains are linked up in 5-car, A-B-B-B-A sets, but also can be linked in sets of 4 cars (A-B-B-A), 6 cars (A-B-B-B-B-A), 9 cars (one 5-car set and one 4-car set), or 11 cars (one 5-car set and one 6-car set).

Currently, most R142s are maintained at the 239th Street Yard and East 180th Street Yard and assigned on the 2 and 5, with the remaining sets maintained at the Jerome Yard and assigned to the 4.

The R142s feature Alstom ONIX AC propulsion systems, electronic braking, automatic climate control, electronic strip maps, and an on-board intercom system. The R142 and the R142A was partly designed by Antenna Design.[6][7]

Like the R110As, the R142s feature wider doors than past A-Division equipment, with 54-inch side doors (about 9 inches narrower than the R110As' 63-inch doors, but 4 inches wider than the R62/As' 50-inch doors). All car ends have windows, allowing passengers to see through to the next car, except cab ends, where the cab walls prevent such visibility. The R142 car bodies are constructed from stainless steel.[8]

On April 30, 1997, the Board of the Metropolitan Transportation Authority approved the purchase of 680 cars from Bombardier (the R142s) and 400 cars from Kawasaki (the R142As). The original purchase order was for 740 cars, but because of the intense competition between the firms, the MTA was able to purchase 340 additional cars at the same price. The entire cost of the purchase was $1.45 billion. The new subway cars were based on the results of the tests from the R110A and R110B test trains. The historic deal came after round-the-clock negotiations and the contract was the largest subway car purchase in the history of the New York City Subway up to this point.[11]

The first ten R142s, 6301–6310, were delivered on November 16, 1999. However, minor issues were reported to be found and have since been corrected during troubleshooting during the testing phase. After several months of testing and troubleshooting of all bugs, the R142s were placed into revenue service on the 2 on July 10, 2000, and the last R142s were delivered by mid-2003.[12]

In January 2019, the MTA proposed mid-life upgrades to several train subsystems in the R142/A fleets. These included changes to the HVAC, propulsion, and door systems; the addition of Ethernet on the R142 fleet; and conversion of the fleet to be compatible with communications-based train control, in conjunction with subway signal upgrades along the IRT Lexington Avenue Line. The R142 fleet would also be retrofitted with a "monitoring and diagnostics system".[13]^:23

On March 27, 2020, a northbound 2 train with operating lead consist 6346-6350 and trailing consist 6366-6370[14] caught fire while traveling from 96th Street to Central Park North–110th Street. The fire erupted on board car 6347, damaging that car, as well as additional fire and smoke damage to the rest of the set, along with some moderate fire damage to the station as well. As a result, the whole set has been taken out of service.[15] The train operator was killed and 16 people were injured.[16][17]
