Hot, What was the point of putting the engine into reverse and cracking the throttle? What was supposed to be the desired outcome?

Would it have been a better idea to immediately bail off on the engine brake, and wait for the train to come to a stop?

From what I was told, the entire short train's (seven cars IIRC) brakes were not enough to hold back the high HP diesel.  The train had been in emergency for some time and wasn't slowing down.  The fear was that the brakes were going to overheat and fade soon, and the diesel was located in an inaccessible location in the train (water cars in front, and a box car behind).

Not to mention that the current manager always ran with the "mountain cock" cut out, i.e. the driver brakes would not come on on 844, thus they never had to "bail off" the independent brakes. Reportedly, the FRA folks were NOT real pleased with THAT "plan".

What makes no sense to me is when the air was dumped and went into emergency, why didn't the diesel immediately drop the load and go back to idle? The diesel was still pushing after the train was in emergency. Even if everyone 'forgot' about the MU box was still in run, the emergency brake application would have over ridden that.  Electrical malfunction was the cause, not human error.

There was no PC function built into the Diesel MU Control box, as the designers made the assumption that the operator knew what the he)) he was doing. Besides, simply dropping the Generator Field button, would have unloaded the MU'ed diesel units.

Nope! You have no idea what you are talking about!

 

So the whole train would brake in emergency, the diesel would have it's brakes applied and still pushing? I know you can't control the diesels' brakes from the steamer control stand, so you are telling me there was no over-ride safety that would throttle the diesel down unless it was done manually? So they forgot about the field switch too?

Yes, that is EXACTLY what happened! There is even video to prove it.

That is wrong, as the independent air is also MU'ed to the trailing MU'ed diesel units! Again, you don't know what you are talking about.

Correct! However, the NKP 765 group have since modified their EMD supplied Diesel MU Control Box with PC protection, at the request of the Norfolk Southern Mechanical Dept..

Thanks to Hot Water we can see the absurdity of the current manager of the UP Steam program, how sad.I feel happy that I had the oppurtinity to ride behing 3985 and 844 while they were running,we may never get the Chance again.

The only "absurdity" here is that one man's personal vendetta continues to be allowed to be posted to this day!

Mike,
I have confidence that if the UP wants to run 3985 & 844 again, they will. What you really need to worry about is the UP hierarchy being invaded by the kind of people that don't like steam.

I am sitting back waiting to see if there is enough meat on a crow for more than one person to eat.

Yeah guys, let’s try to get back on track. I just want to hear about the Big Boy, not some excursion from 2011.

The Steam program has got to show a real payoff. It has got to show a relivence. UP management is no longer going to allow money to be flushed down a steam restoration toilet. Back in the Steve Lee era it did totally justify its existence as a PR tool. It stopped doing that right after the management change. It went from being a functioning viable steam program to a invisible  steam shop. That is what is going to kill the UP steam Program in the end. I personally already think its to late. The lack of presence has already killed it.

Put in a call to Hollywood for their best stunt man!  "Roof walk?  I don't need no stinkin' roof walk!"
