R110B (contract order R131) was a prototype class of experimental new technology New York City Subway cars built by Bombardier of Canada for service on the IND and BMT (B Division) services delivered in 1992 and entered service on June 15, 1993 on the A service. The R110B was designed to test various new technology features that would eventually be incorporated into the R143 and was also not intended for long-term production use.
There were nine R110B cars, numbered 3001-3009, which were linked into three-car sets. The cab cars are powered with four traction motors each. The center car of the 3-car set is an un-powered, cab-less trailer. The cars are typical B-Division size, except that they are 67 feet long, a length shared by the BMT Standards, and the SIRT ME-1, along with all of the SEPTA's Broad Street Subway cars and the current PATCO fleets.
The R110B uses the standard subway train control stand, but with some added computerized features. The layout of the controls is desk-style, with switches, lamps, and a single lever to control traction and braking. A CRT with function keys on either side is used to monitor speed, train status, etc.
The R110B's design is similar to the R68 cars now in use on the BMT and IND lines, but the ends are more square and Lexan glass is used in the windows. Car ends that do not have cabs have an expanse of glass, which makes the car feel open and airy. The seating configuration is the same as in the R68, but the materials are improved.
A matte plastic is used that allows scratches, tags and stubborn graffiti to be buffed out using a light abrasive. The seats have a reduced bucket. Internal surfaces are tan fiberglass and plastic, with accents provided using a plastic mosaic applique. The floor is linoleum with a pattern of slightly raised and textured squares. The R110B cars have a few handholds for shorter passengers.
There are rollsign line indicators line indicators in the front of the train; LCD destination signs (on windows) and interior strip route guides on top of the ad space with LED indication of stops ahead on both sides.
Another new and important feature is a passenger intercom, which can be used for emergencies.
On November 4, 1996 there was a fire and explosion on R110B car #3006 while in service on the A train. The whole set of #3004–3006 was permanently taken out of service. From then on the two remaining sets run as a six car train on the "C" line.
Due to breakdowns, set 3007-3009 was cannibalized for parts for the remaining two sets, which then ran on the C. The train has not had the computerized voices and next stop indicator signs programmed for the "C" service, so the conductor made the announcements manually.
Retirement and after service life
Throughout 1999, the R110Bs had been in and out of service for both repairs and additional component testing. It was permanently removed from service in 2000 due to breakdowns and low Mean Distance Between Failure (MBDF) numbers and will not see revenue passenger service again.
After retirement, some cars were saved for various purposes though out the New York City Subway system, including:
- 3005 - used as a training car at P.S. 248, the New York City Transit Learning Center since July 15, 2004. This car replaced R16 6452.
- 3004 and 3006 - used as training cars at the Coney Island Yard's firefighting facility since August 2004. These cars replaced R30s 8392 and 8401.
- 3001 - sent off to College Point, Queens in early 2014 for use as a training car for the NYPD.
