The slow take off is due to a DDEC protocol called "SMOKE MODE" which prevents less Particulate Matter and reduced NOX levels which in conjunction with the Catalytic Converter muffler allows it to meet EPA and CARB with no problem. NYCTA Buses of the same year 1997-1999 all have that setting if the engine is Non-EGR (Exhaust Gas Recirculation)
So much faster than the 6v92. It was a major improvement over that engine. Even though bus fans still admire the sound of the 6v92 I personally loved the series 50 because I appreciated the substantial power increase
Gosh I miss riding the 8600s and 8900s they had on the M101 from midtown to Washington heights!!! My favorite part of that line is the hill from 125th to around 135th streets off of Amsterdam Avenue. Due to the viaduct. Those series 50s used to pull so hard uphill.
correct. This is ex-Gardena #792. The new owner didnt like those nasty green hard seats...so he removed them and swapped seats with an ex- LA Metro RTS he had scrapped.
To me it sounds like a series 50 with the Allison V731 transmission. The V731 whines really loud as you can tell on RTSs and Flxible Metros. You can definitely tell when the coach is stopped its a Series 50. And the V731 does whine while the bus is in motion but I think it may be quiet while stopped but Im not sure.

The same colors and style used on AMA buses in San Juan from 1992 thru 2002, rubber grab rails on seats only on 1992 units
Love it when you operate Series 50s!

Could be a throttle delay, DDEC issue, or the way that engine is set. It's a variety of things

thank you for the explanmation it makes a lot of sense
He probably didnt get to upload the details & its an RTS as the TITLE says. Its a Detroit Diesel 50 Series Engine - Allison VR-731 ATEC Transmission.
That DDS50 has a little DD6V92 in the soul lol

Correct on the powertrain. I just uploaded the video late night. turned off the monitor, as I was already tired.
detroit 50 series?
oh yeah it will still be here when you come visit. have your recorder with you becuz you will leave here satisfied
This was before the blue seats
Looks like a Flxible Metro. Could you please provide more details as to this unit (who did it belong to, what powertrain)?
Good Job ea90744 to the Omnitrans Bus RTS T80206 #2697 Today!
I just noticed this has a "late" slip is that normal?
The transmission is a little worn out... and this with this bus still being pretty old at at the time I'd say yeah, its pretty normal.
