- Greetings folks!
-
- Last weekend the NYCTA had both of the New Technology trains (R-110a
- and R-110b) on display on the downtown express track on the BMT
- Broadway Line at Herald Square, and I managed to spend a few hours
- there examining the trains. I also spent some time talking to
- employees of the TA and the manufacturers of the trains.
-
- Note that I am referring to these beasts as trains as opposed to cars.
- This is due to the fact that both are permanently coupled trainsets --
- the R-110a having a minimum length of 5 cars, and the R110b having a
- minimum length of 3 cars.
-
- With amazing common sense, the R-110a is destined to live on the A
- Division, otherwise known as the IRT (numbered lines) and the R-110b
- is headed for the B Division, otherwise known as the BMT and IND
- (lettered lines).
-
- Both trains are scheduled for test in revenue service in April.
-
- Some new features are common to both trains:
-
- 1) Computerized traction and braking control -- a single lever
- controls both acceleration and braking.
-
- 2) AC Traction Motors controlled using choppers.
-
- 3) Battery powered operation. Power from the third rail is used to
- charge batteries, from which power is drawn, converted to AC, and
- passed to the AC traction motors. This will allow trains to proceed
- to the next station (or back to the previous station) in case of a
- loss of third rail power.
-
- 4) Air bag suspension. Compressors are used to inflate air bladders
- which are used instead of springs. A computer continuously monitors
- the train, adjusting the inflation of the bags and keeping the train
- level.
-
- 5) Passenger alarm system. A pressure sensitive tape switch is
- mounted throughout the interior of each car. When pressed, the
- operator is notified, and a light on the outside of the car comes on,
- alerting police as to in which car the emergency exists. (this has
- already been installed in some cars on the J line).
-
- 6) Door motors are now electronically controlled and use worm drive as
- opposed to the older lever style actuators. It is now impossible to
- force a door open once it is closed.
-
- 7) Electronic route/destination signs and synthesized voice station
- anouncements controlled from the cab (already on some newer R-60
- cars).
-
- 8) Automatic climate control. All Heating and Air-Conditioning is
- controlled automatically using a thermostat in each car. The cars
- switch automatically between heating and cooling as necessary.
-
- 9) Exterior appearance. Both trains are in the now-standard stainless
- steel and glass.
-
- About the R-110a:
-
- Manufacturer: Kawasaki
- Status: Now in use in Kansas City?
- Loading guage: 8.5 feet (IRT)
- Car length: 54 feet
- Coupling: N2A
- Minimum configuration: 5 cars
- power cab 4 traction motors
- power battery 2 traction motors
- trailer battery
- power battery 2 traction motors
- power cab 4 traction motors
- Destination/route signs: LED line indicator signs (1,2,3,4,5,6,7)
- LCD destination signs
- LED interior next stop signs
- Control stand:
- The cab is completely 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 a LCD flat panel graphic/alphanumeric display (as in a
- laptop computer). The display is used in conjunction with
- the keypad to control doors, reset alarms of various sorts
- (including the silent passenger alert system), display train
- speed and braking information, etc.
- External:
- Not much different from the current R-62 cars now in use on
- the IRT, except for slightly squarer ends in black lexan (or
- possibly glass?), and the considerably wider passenger entry
- doors (about one foot wider than the R-62 doors).
- Internal:
- Seating has been improved, giving up the scoop seats in
- favor of comfortable benches (those who are more than skin
- and bones will rejoice) in bright colors. Pattern is now
- parallel across from front/back facing -- rather like the
- R-60 cars, but with one side shifted from the other, so that
- the front/back facing seats are opposite benches which are
- parallel to the side of the car. Unfortunately, some
- seating space has been sacrificed in order to allow for the
- wider doors. Interior surfaces are smooth fake-granite
- fiberglass (or plastic?) -- which is apparently quite
- resistant to graffiti, and also quite cheap to replace when
- necessary. There is the typical shortage of handholds --
- especially for shorter individuals who cannot comfortably
- reach the horizontal bars above the bench seats. Also, the
- wider doors leave a huge gulf with no handholds whatsoever.
- The floor is still that horrible smooth linolium which looks
- dirty even when it's just been cleaned, and which gets
- terribly slippery when wet.
- Comments:
- Unfortunately, on the morning of the exhibition they
- couldn't manage to get the R-110a to operate -- some problem
- with arcing when trying to start up the traction motors. So
- they hooked up two diesel-electrics (one to either end)
- and hauled it dead to Herald Square. This was apparently
- quite a tricky operation, as the dead train had little
- braking control, and there was no MU connection between the
- diesels. The operators communicated using a kludged up
- hardwired headset rig wired straight through the train (the
- car-end doors were left open).
-
- Other than that, this is an impressive train, with a lot of
- very new technology. Especially the new suspension and
- traction control systems. The next stop signs are a very
- nice touch, as are the wider doors.
-
- About the R-110b:
-
- Manufacturer: Bombardier
- Status: Prototype
- Loading guage: 10 feet (BMT/IND)
- Car length: 70 feet
- Coupling: BABCO
- Minimum configuration: 3 cars
- power cab 4 traction motors
- trailer battery
- power cab 4 traction motors
- Destination/route signs: Roll-sign line indicators (most letters)
- LCD destination signs
- Interior strip route guides with
- led indication of stops ahead.
- Control stand:
- This is a pretty standard subway train control stand, to
- which some computerized features have been added. The
- layout of the controls is desk-style, with a myriad of
- switches, lamps, and a single lever to control traction and
- braking. A CRT with function keys on either side has been
- added, and is used to monitor speed, train status, etc.
- External:
- Similar to R-60 cars now in use on the BMT and IND, the ends
- are a little squarer, and are lexan (or glass?). Car ends
- which do not have cabs are open (again lexan or glass).
- Internal:
- Seating is basically the same as in the R-60's, but the
- materials have been improved -- a matte plastic is used,
- allowing scratches and stubborn grafitti to be buffed out
- using a light abrasive. The seats are still slightly
- scooped, but not as much as before. Internal surfaces are
- fiberglass and plastic in the wonderful TA tan (ugh!), with
- some accent provided by a plastic mosaic applique (begging
- to be peeled off by vandals). The floor is linolium with a
- pattern of slightly raised and textured squares, which
- should be quite good when wet. We still have the handhold
- shortage for shorter passengers. Added, however is a
- passenger intercom -- which can be used to call for aid in
- an emergency. Also, the clear non-cab ends of the cars
- make them feel much more open and airy.
- Comments:
- The R-110b, unlike the R-110a, managed to both arrive at,
- and depart from, the exhibition under its own power. It was
- _quiet_ -- incredibly so. This probably has to do with the
- smoother traction control and the better suspension systems.
- The drivers are going to be using the horn quite often,
- because a train could very easily surprise someone standing
- close to the edge of a platform.
-
- I liked the open feeling of this train, and the excellant
- signage, but was disappointed with the drab colors used on the
- interior surfaces.
-
- Has anyone else out there had a chance to see these trainsets? I
- think (and hope) that I have covered everything -- if you have any
- questions, I'd be happy to answer them if I can...
-
- Enjoy...
