Why do _school_ buses sound different as compared to any other type of vehicle?

I asked this question on Google and got a couple of good theories, but no definitive explanation. You can always tell when one is coming, even if you can't see it (over the rise of a hill, for example). Greyhound buses, RVs, motorhomes, dump trucks, semis - school buses don't sound like any of those. It's been suggested that the long exhaust pipe and/or long drive shaft may contribute, but why wouldn't the other "long" vehicles sound like that? I'm sure you all know the sound I'm referring to, it's a particular type of whine (gear noise maybe?) that increases relative to the speed of the bus.
