During the early 1990's, two trains (R110A & B) have been undergoing strenuous tests for the next generation of subway cars. Among the improvements are:
The R110A is for the IRT lines and is a ten car train. The R110B is a nine car train of 67' cars for the BMT and IND. A 9 car train is about as long as a 8x75' or 10x60' train.
To be more accurate, the R110 contract was for the specifications for a new generation of cars. The actual contracts for construction should have been R130 for the IRT and R131 for the BMT/IND cars.
The column marked NYSR Page in the car type tables contain links to the New York Subways Resources Web pages for each of the fleets.

to be enough cars to replace remaining R32 to R42 cars. But the increase of
R160 makes this moot. October 2009 this will replace 272 car R44 fleet with 60' cars. June 2010 with the service reductions of 2010, the R44 fleet was removed from service. This returns the R179 contract to the replacements for the remianing R32 and R42 50 five cars sets for the R32 replacements and 10 four car sets for the ENY R42 replacements. There might be an option for 10 more five car sets. March 24, 2012 The main 300 car order awarded.

Update January 21, 2012: The contract has been modified
to purchase 103 cars and a total of 37 C cars. A new total of 370 existing
R142A cars will be converted to CBTC. The net changes will project 473 cars,

One unit of R160 cars had a 6th car added to make up an 11 car test train (5+6) for operation on the to alleviate overcrowding. Since the cars have link bars, the addition had to be done in the shop. The cars involved were: Units 93539357, 93639367 and 93689372. They were reconfigured into a single 11car test train. Cars 9363/9364/9365 were linked to 9370/9371/9372 to form a 6car set and coupled to unit 93539357.
The R142 and R142A's will be in permanently coupled sets of 5 cars. The end cars will be the only ones with cabs and will be numbers xxy1, xxy5,xxy6,xxz0 (z is the next tens digit after y). So a typical train will be:
7521+7522+7523+7524+75257226+7227+7228+7229+7230
+ is a drawbar
 is a coupler
This numbering scheme is a direct result of the screwy method introduced
by the R62 and R68A cars. If the block began with '00', the cars would have
been more logical with the 0,4,5,and 9 endings being the cab cars:
7520+7521+7522+7523+75247225+7226+7227+7228+7229.
I guess that'll be the
puzzle for future railfans to ponder.
However, this is all moot. The R143
cars are four car sets and the R160 contract, where units are in four or five
car blocks. so forget about any logic in where the numbers break between
units.
With the delivery of the R143 and R160 fleest, even this scheme
has gone by the wayside with the four car and five car units mixed in the
contracts.
The 30 day testing for the R160B Kawasaki train is complete, the testing for the R160A Alstom train began on 10/14.2006.
Good News/Bad News/Good News: Although the CBTC system is almost ready on the Canarsie line, full implementation must be delayed until additional R160A1 cars are available because ridership is up and more trains will be needed. R42 cars will be used and the old signal system will continue in service until then.
Arriving just under the wire for 1999, the 'PILOT' cars for the R 142 and R 142A contracts reached NYCT rails on December 20, 1999. As of February 2000, there are ten R 142 cars (60016010) and ten R 142A cars (72117220) on the property and ready for testing. They will be tested on the Dyre Ave test track between Dyre Ave and Morris Park. There will also be speed tests on the Rockaway flats.
The tests will last about five months, then there will be a 30 day in service test for each train. The trains must operate without problems for the full 30 days before the remainder of the fleets will be approved for shipment.
Bombardier shipped two production cars (6311 and 6312) for the 207th Street Shop for training mantenainers and supervisors on inspection and repair procedures.
The Bombardier cars were shipped by rail via the Delaware & Hudson, Hudson Division of MNCRR to Oak Point. From there the NY&A picks them up and takes them via the Hell Gate Bridge to Fresh Pond Yard (of the LIRR). Here the cars are removed from flat cars and assembled onto their trucks. From here the NY&A takes them to the Linden Shop of NYCT. There a TA diesel pulls them up the ramp to the IRT Livonia el for the trip to E180th St yard.
The Kawasaki cars are fabricated in Kobe Japan. The bodies and trucks are shiped by boat via the Panama Canal to Port Newark. Each car is on its own flatbed trailer, much like the recent delivery of the LIRR (photo taken at NJTP exit 14A) cars in 1999. From there they are trucked to Yonkers by highway. The cars are finally assembled and tested there. They are then trucked to 239th Street Yard, where they are placed on NYCT tracks.
The R142 (Bombardier) and 142A (Kawasaki) will operate on the #2 and #5 lines. Their configuration will be ABBB'A. The B' cars will be wired in reverse so the trainline connections will be correct. Although draw bars will connect the units, they can easily be reconfigured into ABB'A four or ABB'BBA six car units. Because the B and B' cars have the air compressors, units may not be less than four cars (two compressors are required on each unit). Also more than four B or B' cars won't work since the those cars have only two traction motors. The A cars have four.
The R142 test units (10 cars) are scheduled to arrive in May 1999. The test units for the R142A are scheduled for November. Boths sets will be tested for about six months. When all are accepted, cars will be delivered at a rate of 40 per month.
If the options on both contracts are exercised, there will be a total of 1400 cars, enough to replace all of the R26, 28, 29, 33 and 36 cars.
The R143 BMT/IND contract was increased from 100 to 212 cars. They will be used mainly on the L Canarsie14th St line. This line is the first to have Communication Based Train Control (CBTC). The R143 will be equipped with that system.
