The 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 cars were ordered from Bombardier in December 1989. They were designed to test various new technology features that would eventually be incorporated into the R143 and were not intended for long-term production use.
There were nine R110B cars, numbered 3001-3009. The cars were linked into three-car sets by consecutive numbers. The cab cars are powered with four traction motors each, while 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 that of the R68 cars now in use on the BMT and IND lines, but the ends are more square and use Lexan glass 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 more advanced.
