The R-110A (contract R130) was a prototype class of experimental new technology New York City Subway cars delivered in 1992. The R110A was designed to test out new technology features that would be incorporated into the R142 car order, and it was not intended for long-term production use. Built by Kawasaki Heavy Industries, there are ten cars, unit numbered #8001–8010, and they were permanently linked in five-car sets. Between 2013 and 2014, all the B-cars (#8002-8004 and #8007-8009) were converted into flood pump cars.

Background

In each five-car set, there is a full-width cab at each end. The cab cars are powered by four traction motors each. The center car of each five-car set is an unpowered trailer, and the other two cars are powered by two traction motors each.

The cab is computerized, with a control stand consisting of a single lever for traction and braking control, a reversing key, a small numeric and symbol keypad, and an LCD flat panel display. The display is used in conjunction with the keypad to control doors, reset alarms of various sorts including the passenger alert system, display train speed and braking information, and do much more.

The R110A cars are similar to R62s, but they have squarer ends and wider 63-inch passenger entry doors (over a foot wider than the R62 doors, which were 50 inches). All car ends have clear lexan glass, allowing passengers to see through to the next car, except on cab ends. Their bodies are stainless steel.

Seating is improved by eliminating the bucket seats in favor of comfortable benches in bright colors. The benches, unlike the R62 cars, have some forward-facing seating combined with standard longitudinal seating. One side is shifted from the other, making part of the bench on one side of the car face a door on the other side. Some seating space is removed to allow for wider doors. Interior surfaces are fiberglass, which is resistant to graffiti.

There are LED exterior line indicator signs on all cars, LCD destination signs in windows, and LED interior next stop/variable message signs inside the cars. The LED display on the front of the car could either be red, for Broadway–Seventh Avenue Line service, or green, for Lexington Avenue Line service.

History

The R110A cars entered service on June 15, 1993, on the 2 service. In 1999, they were pulled out of service due to brake problems and fire damage, and were transported back and forth between IRT line yards and stored until 2013.

Reconditioning and current status

In 2013, it was decided to convert the cars to pump cars as the car bodies had many years of service left on them. Cars #8002–8004 were converted to pump cars in 2013 until summer 2014, while #8007–8009 were converted in the fall 2014. #8005 was completely stripped of parts to become a pump train as well; however, the conversion process was halted sometime in 2014 as it was decided to use only the B-cars for pump train service. The B-cars were renumbered to #P8002-P8004 and #P8007-P8009 after conversion.

A more detailed list of the known statuses of the ten cars is below:

• #8001 and #8006 – Missing various components, and currently stored at 207th Street Yard. Future plans for these cars are unknown.
• #8002–8004, #8007–8009 – Converted to pump/reach cars, renumbered to #P8002-P004 and #P8007-P8009 respectively, and currently stored at 207th Street Yard.
• #8005 – Completely stripped of parts, remains in 207th Street Yard. Future plans for this car are unknown.
• #8010 – Remains in its original condition in 207th Street Yard. Future plans for this car are unknown, though recently it has been located on the same track as other subway cars slated for preservation.
