This bus got converted into Diesel recnetly and it got repower with Detroit Diesel Series 50 EGR and Allison B400R 5-speed transmission with 4th generation controller.
My guess....it has something to deal with the filters.
You can hear the "pipe scream" (what I like to call it) on buses with a John Deere 6081, Cummins L Gas+, and Detroit Diesel S50G engine. You won't hear it on a C40LF with the C Gas+ engine, as they have that rhythmic hissing noise.
Now in some cases, there may be an overblown turbocharger (on a diesel powered bus) that makes a bus whistle quite loudly. See the video of SEPTA Neoplan 3426, you'll find out.
see my moms coworker said that they (some) whistle because of the a/c fan that usually has 5 blades but in the summer need to stuff 6 blades in it and it creates that loud whistle i always hear..if that was understandable...
Another thing I like of this bus (and other New Flyer D40LFs 1998-2003) is their own unique interior noise combined with the drivetrain noise. How's that?
Nice sounds more like a detroit diesel seires 50 man i wish these buses are on service in vancouver so it will be good usualy these buses are operating in Coquitlam new flyer buses rock w00t lol noob.
nope. closest you'd get to an L-10 powered New Flyer 40LF is WMATA of Washington D.C. They have ISM/Voith 864.4ADRs. I beleive there's another property in the US that uses ISLs/Voiths but i cant think of the name
Do they still operate these buses? i never see them anymore

Check out the few that Montigue M. (MetroLinerXLZ) has on his YT network.

Is it true that this bus will sound close to a Gillig with equivalent powertrain if it had a Meritor RC633 rear axle?
ClassicTVFan82 4 years ago
Sounds like a Adelaide MAN SL202

Voiths are also known for retarder whistle.
ClassicTVFan82 5 years ago
Because the sound from the retarder, the retarder whistle is the unique of Voith transmission~~

Whistling is a natural happening stance with most turbodiesel engines.

Are there any US properties that run New Flyer C40LFs with the Series 50G and D863.3?
ClassicTVFan82 5 years ago
i just noticed that this bus has a longer 1st gear than the buses in Las Vegas (CAT)
brownbrownson 5 years ago
Voiths are known for their deep 1st gear ratio. That's 6.13:1, compared to the Allison B400R's 3.49:1.

Also, are there any C40LFs out there which use the S50G (EGR version) with Voith D863.3 or D864.3?
ClassicTVFan82 5 years ago
None of them, coz' we don't have S50G (EGR Version) C40LF~~

How did you make the transitions in this video from the bus departing the garage to you inside of the bus?
ClassicTVFan82 5 years ago
Were there any buses in fleet #3283-3308 that received both the Cummins CG280 and Allison B400R5 following their recommission?
ClassicTVFan82 5 years ago
None of them received Cummins CG280 and Allison B400R5 when they're recommissioned~~
3290 was received Allison B400R5 with original Detroit Series 50G engine~~
3288, 3292, 3302, 3306-3308 were received Cummins Westport C Gas Plus 280 engine and retain the original Voith Diwa 863.3 transmission~~

In vancouver. In between the skytrain (the overpass you see) and a highway. I think it's in central Burnaby at Sperlink Skytrain Station.

Please tell me, are there any C40LFs throughout North America which use the Cummins L10G with Voith DIWA863.3?
ClassicTVFan81 5 years ago
nope. closest you'd get to an L-10 powered New Flyer 40LF is WMATA of Washington D.C. They have ISM/Voith 864.4ADRs. I beleive there's another property in the US that uses ISLs/Voiths but i cant think of the name

Tri-Met of Portland, OR has New Flyers with the ISL and D864.3E. MTA Maryland of Baltimore, MD, uses the ISM and D864.3E in their New Flyer D40LFs.

Ride-On of Montgomery County, MD operates a handful of Orion VII 35' buses with this drivetrain.

Actually sounds quiet, compared to the blaring roar of many diesel engines.
VancouverDriver 5 years ago
yea right! Ride Cleveland's 1998 NovaBus RTS's. Series 50G/Allison VR-731 ATEC and they are jus as loud as their diesel powered brothers.
