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.

Description

The R110As are numbered 8001-8010, and the order is split into two five-car sets that are permanently coupled together. At each end of the five-car set, there is a full-width cab. 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 64-inch passenger entry doors (over a foot wider than the R62 doors, which were 50 inches) that are staggered for better passenger flow, because passengers would stand in the niche instead of in front of each door. All car ends have clear lexan glass, allowing passengers to see through to the next car, except on cab ends. The famous Italian designer Massimo Vignelli was hired to design the car interior with the Metropolitan Transportation Authority Arts for Transit program. The R110A has very bright colors with speckled black floors and with walls that are speckled gray. Unnecessary edges were removed from stanchions, boles, and bars to create a smoother and cleaner appearance. The United States Department of Transportation National Endowment for the Arts gave the 1995 national award for transportation design as a result of these efforts.

Seating is improved by eliminating the bucket seats in favor of comfortable benches in bright colors. The interior has longitudinal seats on one side and transverse seating on the other, unlike previous IRT cars, which since 1910 have always featured all-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. As a result, there was a significant reduction in seats, from a total of 440 in a train of R62As, to 264 in a train of R110As. However, the number of standees went up from 1,332 to 1,684. The seating capacity is 24 in the A cars, and 28 in the non-cab B cars. As a result of the loss of seats, there were complaints from the riding public, and as a result, most of the seats were restored on the first New Technology Train orders, the R142s and R142As.

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

During the 1970s and 1980s, the Metropolitan Transportation Authority had made several large orders for subway cars, such as the R46, which had new components added to them. However, because there was not a prototype built first for testing, many expensive retrofits were required. The Metropolitan Transportation Authority was in the process of creating the first technologically-advanced subway car since the R44 in the early 1970s. In 1989, the MTA awarded contracts for two prototype test trains, one of which was the R110A (contract R130) for the A Division built by Kawasaki Heavy Industries, and the R110B (contract R131) for the B Division built by Bombardier Transportation. In order to avoid the aforementioned problem, in 1989, the MTA awarded contracts for two prototype test trains, one of which was the R110A (contract R130) for the A Division built by Kawasaki Heavy Industries, and the R110B (contract R131) for the B Division built by Bombardier Transportation. The cost for each R110A car was $2,209,000.

These two fleets, were called the New Technology test trains (NTTTs), and would test features that would be implemented on future mass-production orders. The R110A tested new technology including AC propulsion with regeneration, microprocessor-controlled doors and brakes, roof-mounted hermetic air-conditioning units, and fabricated trucks with air bags suspension. Passenger emergency intercoms for contacting train crews, passenger alarm strips to press in case of an emergency, improved lighting, glass to see into the next cars and the platform, and computerized announcements were all implemented.

The R110A cars entered service on June 30, 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.
