Re: D&S Diesel #107 Smoke and mirrors

DW,

I love the Sandman reference but Grandmother had been gone for 25 years before that was around, a Morris Ten was what she drove, with running boards too.
I doubt that the MLW has a variable geometry turbo on it, I think you are referencing a truck or bulldozer replacement like the Switchblade turbo there.

I didn't see or hear any abnormality in both the video's on the D&S, just than a brand I've only seen crawling around Skagway's back streets and docks and they didn't do any rapid windup while I was around. I had been surprised on actually seeing the MLW's in operation 91998) just how clean the exhaust was given the crap reputation ALCo has. We only had English Electric and General Electric(turbos) prior to the Wisconsin Central ownership of NZR and subsequent turbo'ing of the GMD D^F's in the mid-1990's, so I was used to well maintained and serviced units thus emitting very little smoke on a daily basis, other than the prolonged idling "carbon up" of the GM's and cold starting the GE's.

Our Enginedriver's exams required competency in all aspects of the locomotive not just the rules&regs eh. I had to be able to describe the difference between an EMD exhausting "carbon up" smoke after a rainyday 4 hr parkup and a failed turbo clutch on a GE. I experienced the latter once, 6kmh upgrade with a light load of just under 200 tonnes, with the wind travelling at the same speed enveloping the loco with a huge choking cloud of filthy exhaust, probably why my lungs aren't that great now.

I drew my previous post from memory, a little hazy now so here's the actual one of my 1982 Enginedriver's Diesel Examination (4 assignments, 94 questions in total).
