I'm wondering if anyone besides me has a favorite bus/engine/transmission combination because of the way it sounds? Obviously a lot of us are fans of screaming two-stroke Detroits, but does anyone have another one they personally like? For me, it's a Nova Bus Classic with a Detroit Series 50 and an Allison B400R transmission. In this case the transmission is heard much more prominently than the engine, and I find the B400R's whine under acceleration very pleasant to listen to. Calming, if you will. My local system had such a Classic, until it was retired in 2014 when the transmission failed. 3:10 in this video: Trent
I've been traveling on Greyhound for almost a year now and a thought struck me the other day when i was coming back to Toronto from Rochester, New York. It seems that the new Prevost buses aquired by GH Canada aren't actually new. The new X3-45's are always on the New York City-Toronto and London-Detroit-Chicago routes but never on any local routes in the GTA. They do however operate x3-45's with fleet number 88xx but a driver told me they were from 2008 and were transferred to GH Canada in 2014. He told me when they came to Canada they were plagued with problems. Transmissions were falling out of them, body damage, ripped seats, power outlets not working and missing buttons and such in the drivers area. My question is, if Greyhound is advertising the purchase of new buses (86xxx), why is the Canadian side getting the shitty end of the stick? The bus I was on was really nice, the seats had seat belts, the outlets were REAL power outlets, and the drive was smooth. All the older MCI buses from the US is being sent to Canada for a 2nd life but why be greedy with the new fleet if they're practically the same company?
Does anyone have any information regarding the Renk-Doromat 874 series transmissions that were used, among other applications, in the MAN articulated buses? Stuff relating to specifications as gear ratios and input power/torque. Thank you! Models in this series included the 873 (3-speed direct-drive) and the 874 (overdrive in 4th). The model 874 was updated twice (to 874A and 874B). The only non-MAN bus applications I can think of, here in the U.S., are the 10 Orion I model 01.507 buses (units 501-510, built 1986) ordered by Intercity Transit of Olympia, WA. Orion cataloged that transmission alongside the Voith and ZF (and the more common Allison units) through 1989 or 1990. Again, I am unsure if any other non-MAN-related bus builders (at least here) ever cataloged it. Someone here used to say Gillig offered it too but that rumor was debunked in regard to the Golden Gate Transit 30-foot Phantoms (those instead had Voith transmissions). ~Ben
What are your favorite powertrains? Some of my personal favourties are the 6V92TA/Allison HT-740 to HT-748, the Series 50/ZF, and the Cummins M11/Allison B400R. There are a few more that I really like, but I cannot think of them at the momment.
