Re: Obviously lost an engine and stalled... Yep, I knew that about the stacks, which is why it sounded weird. But, there are some other questions that aren't answered

Yeah, I knew that, they'd done work to raise clearnaces years and years ago, although still "close", so these reports mystified me.... So, it would only be some excess clearance high wide, or something derailing inside the tunnel (it's happened with the draingage issues with the oily water seepage, which have been controlled, and which should not be a problem this summer with the drought) which I was wondering about.
So this "stuck in tunnel" was inadequate power, or power that crapped out? If it crapped out, why did it crap out? Engines emit a lot of CO and CO2, and engines need air, so they all can potentially lose power and/or shut down eventually if stuck long enough... But actually, "nothing" was "stuck" as a result being in a tunnel, other than that poor crew sucking fumes? Of course, a consist can suck a lot of air and needs a lot of cooling air (tunnel motors) pulling a heavy train in run eight, in a tunnel. Did that have anything to to do with the shutdown, or was it mechanical, or cooling related?
What was the length and tonnage, how many units and HPT? PSR supersized? Losing one engine with adequate HPT for the grades on that line (or was it more than one?) and you crap out on those grades is odd? Did the train stall because of the power, or was it something else, like air problems, some combination of factors? Was it PSR "super size" related?
I come from the if it can all possibly go wrong at the same time, it probably eventually will era of "lesson learned" railroading... When you "tied up" the "whole effing railroad" like that, George Delellis wanted to know "why"... Some folks on AP are just "old school" that way....
I still want to know what the hell the routing for this was, and what the gameplan was for getting the train around these fire cloaures? This random "result" of that, needs more of an explanation...
