6000 series

[busfan4022]

Well this morning I rode bus number 6319 on the X9. This bus had a different engine sound compared to the other 6000s. Did the 6000s get the same treatment as the 5300s? With the different engines and all. :(

There is a definite difference in the upper 6200-6300's compared to the 6000-6100's. The engine seems to have a lower bass pitch to it and is somewhat quieter. I am not quite sure exactly what the difference is in engine, but I am sure there are those out there who can clear it up.

This is how the 6000-series break down....

6000-6304: These buses have a traditional Detroit Diesel Engine. I'm not sure which model engine(they are not Series-50, BTW... Only the 5800-Series have this engine type. OT: The 1000-Series have a Cummins Engine).

6305-6329: These buses are a small order that have a Cummins Engine. 6319 sounds different because it is a Cummins Series Engine. Again, I'm not sure which model engine is in them, but they are Cummins.

Here are the engine types I found on the internet for Detroit Diesels. The one in 6000-6304 is most likely one of the following...

N45, C, H, and 60.

Ah, I see. So they did get the same treatment as the 5300s. Maybe this should be added on the 6000 series bus page. :|

Are you sure it's not a series 50? Granted, I couldn't guarantee that it is, but they sure sound like Series 50 engines to me. They're certainly not 6Vs (as found in the 4400s/5300s). What other transit bus engine was Detroit Diesel building in the mid 1990s?

From the Chicago Bus and Railfan website:

6000-6304 Flxible 1995 40102-6T

6305-6329 Flxible 1995 40102-6C

I would imagine the letter at the end of the model would be the engine.

I guess that they are never going to repaint the 40102-6C (6305-6329), I like their engine sounds better than 6T, They could've loan some of the 6C to forest glen and 103rd.

Again, not sure rmadisonwi. But a Series-50 is what is in the 5800's. And the 6000's sound nothing like them while being driven.

Here's a link that may help us figure out the mystery behind what's powering #'s6000-6304.

Above 6D, it says 6V53, so perhaps this is the engine model?

[busfan4022]

This all confuses me. :|!

[JolietJakeCTA]

The "-6D" is indeed incorrect engine nomenclature for Flxible bus engines. In 1995 there was "-6C8" (Cummins C8.3), "-6M" (Cummins M11), "-6C" (for Cummins L10G natural gas) and "-4D" (Detroit Diesel Series 50).

Also, these engine nomenclatures are not related to what you find on the engine blocks.

#6000 to 6304 use Detroit Diesel Series 50 engines; the Series 50, aka DD50, is the 4-cyl derivative of the 6-cyl Series 60 that you could find in some motorcoaches.

#6305 to 6329 use Cummins M11E engines; the M11E was an outgrowth of the L10. Like the Series 60, the M11(E) and its successor the ISM were used in some motorcoaches.

Thanks for the update, Joliet. There are a variety of characteristic that contribute to an engine's sound, including how the exhaust system is set up. Alas, I never got to ride CTA's 6000s (and likely never will at this point), but having ridden WMATA's Metro Es (with DD50s) and Ride-On of Montgomery County, MD's Metro Ds (powered with DD50/ZF) they tend to have really bassy engines compared to New Flyers.

The fact that the Flxes are "V drive" like older RTSs rather than "T drive" like New Flyers may come into play as well.

That being said - I'm sorry I missed out on the CTA Flxes.

You got until Feb. 7th. If your nearby, take a short trip to Chicago and catch a ride(best chance is a FG route).

I agree with best to catch them from Forest Glen because for last 2-3 sundays ago, I go to Church in Forest Park/ Oak Park area and I've spotted few 6000s on Route 90- Harlem at Harlem/ Lake each of those Sundays. Forest Glen are the best on weekends than 74th. I live near 74th routes and I've barely seen few of their 6000s on weekends except Rt. 63-63rd which is probably the best on Saturday but I doubt it for Sundays tho.
