You know, I do recall seeing that on "MotorWeek" TV. They're also working on vehicles like FedEx delivery trucks. On the GM-Allison test track they had the vehicle stopped, got up to about 10 mph on the electric motor, then the Diesel engine would start, ramp-up, and take-over automatically. We all know that from a standing stop, a huge amount of particulates are belched out of a Diesel truck. That was the focus. The question still remains (maybe I should research this first) but is a CNG bus less pollutive (another word that I probably made up -- I'm sticking with it). At any rate, I'm probably hard on GM because I was forced to buy one as my first car and after 4 senseless failures, I went down the Honda road and never looked back. In Northeastern Ohio, you get bad-mouthed for buying a "foreign" car, with all of the GM and Ford assembly plants around there. And of course we all knew someone who worked for them, so you had to buy one. I was fed up during college when my second Beretta started mixing the oil and coolant due to a blown head gasket. In a heated rage I dumped the Chevy and bought a Barebones Civic DX. The whole family gasped in horror! "Yeah, but it's made in Marysville, Ohio". That was the saving grace. Then when I bought my Evo, my Dad was like, "you know Mitsubishi made planes for the Japanese during World War II" -- mostly razzing me. Some generations just don't give up on International grudges. But for me, GM has rubbed me the wrong way in my generation four times, so I'm bitter. The 4 Honda/Acuras that we've had -- best investment. They've earned my trust.

Anyways, on my Dad's railroad, they shut down the locos at night -- in the Winter they plugged them into a 220V outlet to maintain heat for a slick start. I'm guessing the yard near your house has small "switch" engines, which are hard to start unless plugged-in. Another thing to consider is that they may operate them 24/7 by continuously putting trains together for the open "road", and idle between shifts or during lunchtime. The railroad is a strange employer. Time of day doesn't matter much when you work, and your shift could really vary. If they didn't have a 3rd shift and let them idle all night, that's just, well, not a good idea.

Thanks for the thumbs-up on the post...it's been a while ;-) Honestly I had it coming on some of those as I look back on them.
