The R142 is the first model class of the newest generation or new technology IRT cars for the New York City Subway. Built by Bombardier in La Pocatiere, Quebec and Barre, Vermont with final assembly performed at Plattsburgh, New York, from 1999 to 2003.^[2]

Background

The 1,030 R142 cars have Alstom ONIX AC propulsion, electronic braking, automatic climate control, and an on-board intercom system. The R142 and the R142A was partly designed by Antenna Design.^[3][4]

The first 10 R142s numbered 6301–6310 were delivered in November 1999. Regular service began on the 2 train on July 10, 2000, after several months of testing. The R142s and R142As replaced all of the Redbirds—the R26, R28, R29, R33, R33 WF, R36 and R36 WF IRT cars by late 2003.

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).^[5][6][7] The trains are linked up in A-B-B-B-A sets, but also can be linked in sets of 4, 6, 9, or 11 cars.

The R142/A cars are similar to the R110A cars, with 54-inch side doors (about 9 inches narrower than the R110A doors, which were 63 inches, and 4 inches wider than the doors on the R62/As, which were 50 inches). All car ends have windows, allowing passengers to see through to the next car, except unit ends, where the cab walls prevent such visibility. R142 car bodies are stainless steel.

Recorded announcements

The R142 and R142As were the first fleets to feature recorded announcements.

The recorded announcements are by:

• Jessica Ettinger-Gottesman, 1010 WINS Anchor: Announcements on Lexington Avenue Line 4 5 6 <6> services
• Melissa Kliner: original announcements on the 4 and 5 services outside of Manhattan; these have since been re-recorded by Ettinger-Gottesman
• Diane Thompson: announcements on the 2 service.
• Charlie Pellett: "Stand clear of the closing doors, please" and various public announcements, such as safety announcements, announcements about a delay, and on the IRT trains, transfer announcements at most stations. The female announcers' voices are utilized for transfer announcements on the R143 and R160 cars.

These people were news anchors with Bloomberg Radio at the time the announcements were recorded. Since then, Ettinger-Gottesman and Pellett are now at 1010 WINS-AM and Sirius Satellite Radio working with Howard Stern and his Howard 100 news team.^[8]

Differences between the R142s and R142As

• The R142As external speakers have a narrower rim around the edges than those on the R142.
• The interior speakers on the R142A are recessed into the curved portion of the ceiling while the R142s speakers are located in the middle of the ceiling.
• The R142As have different AC traction motors than the R142. The R142s use Alstom AC traction motors, which are very similar to the ones used on the R160A cars and many R160B cars, while the R142A's use Bombardier (formerly Adtranz) AC traction motors which are identical to the ones used on the R143 cars.^[9][10][11]
• B cars have traction motors at the number-one end.^[12][13]
• The R142A car ends consist of a single fiberglass piece, while the front consists of two separate portions, one fiberglass and one stainless on the R142.
• The LCD destination signs and LED interior passenger information signs on the R142 turn off when changing, while the ones on the R142A switch without turning off.
• R142 cars have a dot-matrix LCD route number display and mosaic LCD destination on the side destination signs, while R142A cars have a mosaic LCD for both the route and destination on the side destination signs.
• The interior red door indicator lights on R142s are directly above the doors near its corners and point downwards towards the floor while the R142A's interior red door indicator lights are located just to the left and right of the doors and point towards the opposite wall.
• The flashing orange closing door lights are slightly larger on the R142s.
• The car end lexan glass windows open through a few tiny screws on R142s compared to the keyhole on the R142As.
• The R142 and R142A utilize different truck designs. The R142 utilizes Bombardier trucks while the R142A utilizes Kawasaki trucks.^[14][15][16]
• The two cars have different HVAC systems. The R142s HVAC is noticeably louder.
• R142A cars contain two more advertising panels than R142 cars.
• The front windows on the R142s are less abruptly curved than the R142As.
• The windows on the front doors of the R142As are smaller than those on the front doors of the R142s.
• The door handles on the car end doors leading from one car to another are different on the R142s and R142As.
• The numbers on the R142As cars are in Akzidenz-Grotesk font while those on the R142 cars are in New York City's traditional Helvetica lettering.
