Difference between Nova RTS and TMC RTS?


Bracamonte

Recommended Posts

TMCs were also built from 1987 to 1994, after that NovaBus took over. Some design differences in the TMCs are most noticeable in the 1990-91 models we have, like 8210, 8212, 8218 as they do not have the rear right-side vents where the HVAC unit is, instead having two wedge-shaped panels in their places...

1987 TMC RTS : 4600-4899 (retired)

1990 TMC RTS : 8000-8396, 8400 (being retired)

1993 TMC RTS : 8401-8564 (being retired)

1994 TMC RTS : 8565-8566, 8600-8703 (being retired)

 

NovaBus RTS:

 

1996 Novabus RTS : 8750-9349

TMC started with NYCTA RTS in 1987, but those have been retired since.

 

The oldest RTS we have are 1990-1991 TMC RTS-06, noticable due to their single-lined destination signs and wedge "pork chop" in the back. Numbers 8000-8396, and these will be retired soon. They were delivered for NYCTA, and were NEVER in Private Lines colors. They have spread to MTAB post-takeover. Example of one, 8106: Notice two things: The destination sign lettering (ONLY on 1990-1993s) and the porkchop

These buses originally had a Series 92 Detroit Diesel, but have since been repowered to a Series 50 with an Allison V731 transmission.

 

 

Next, we have younger 1993-1994 NYCTA and ex-Private company TMC RTS-06.

 

The numbers of the NYCTA start from the end of the 1990-1 TMC RTS and end at 8749 with a gap for the Ex-Queens Surface 8500s Orion V CNGs. The Private Lines TMCs were from a few companies:

Triboro Coach: 7000 series (there are none left)

Green Lines: Low 5900s (one left left)

Jamaica Bus Lines: 1100s and high 5900s (two left, none in the high 5900s)

and most commonly, Queens Surface Corp: 9700s (few left)

 

Note that NYCTA 1993-1994 TMCs have emergency lights and ex-PBLs do NOT. ALSO, NYCTA 1993-94s have the destination sign like the 1990 TMC RTS-06. The PBL TMC RTS-06 have destination signs close to the ones on NovaBuses. Ex PBLs of these have vents on both sides where the triangles on 1990s are, but NYCTAs only have it on one side.

 

The ex-PBL TMCs have all openable windows, no emergency lights, and newer destination signs. Where the porkchop is, there is instead a "vent" on both sides. The specs for these buses in each private bus line are somewhat universal

 

Example of a two ex-Jamaica Bus Lines 1994 TMCs

9755, a ex-QSC TMC

I can't find my picture of 5926, the last GBL TMC left but its pretty much the same

 

For NYCT, 1993 TMC RTS-06s had the same destination signs as the 1990 TMCs, one line of text. They are from 8401-8564.

Unlike the PBL TMCs, they only have a vent on ONE side, the left (if your facing the front of the bus). This stays true for all of New York City Transit's RTS (the PBL's arent) with the exception of 8565 and 8566, which have them on both.

The 8600s, which are 1994s, changed their destination sign to the signs novabuses have.

 

In 1994, NovaBus bought the RTS design and started manufacturing them.

 

They have Detroit Diesel Series 50s with Allison V731s. They range from 8750-9699, 4900-5249

 

They too have a vent on one side, with a plain white square on the other. They have emergency lights also.

Also with the 8600s, the interior light design is the same as all the ex-PBLs

All of those buses had the standard Detroit Diesel series 50 (or DD50 for short) engines EXCEPT for 9140-9149. Those 10 buses had and still do have a Cummins M11E engine with the exception of 9141 (repowered to DD50), 9142 (retired) and 9145 (retired). Also 5075-5124 has a ZF Ecomat-2 HP592C transmission but those are getting repowered to the standard Allison one. 5075 is the only one so far that has the standard reansmission.
