Someone tell me about this... the 1st Generation locomotive running with today's road power.
It's 1750 more horse power, but 
It's a video I just shot the afternoon of January 23rd.

I don't have a one track mind. It depends on the turn-out.

Is that a power-trip or just another pick-up line?

Was it producing power or a dead loco in tow? They may have wanted it for the extra dynamic braking.
Unspoken expectations are premeditated failures.

If you click on the link, I've blogged a bit more about this.
But, just moments before the train started moving, a bell in the GP9 rung and then the locomotive fired up... I was wondering why it was fully hooked up with the ES & AC4400's, not running until the bell and start-up happened.
Through BC until farther southwest is all mountainous.
Extra dynamic braking? I'd appreciate anymore information.

I really don't know much about train operations. I was reading about a train accident and there was this long train that was supposed to go through the Cajon Pass. They did not mention much about enough power to go over the mountain but, they needed 4 locos to go down the mountain with dynamic braking. The wheel brakes would overheat on the long descent.
To finish the story, there was miscommunication, two (maybe it was just one) of the locos had inoperative dynamics and the engineers (lead and helper) both thought dispatch knew about it. Dispatch had also miscalculated the weight of the train by a very large amount. The whole bit hurtles down the mountain at 90 mph and boom!

I read about that recently in an old train mag, there was one other thing. The brakeman in the caboose was trying to set the air pressure lower to help the brakes drag more due to the inop dynamic brakes, but there was a junior engineer operating the train, too, and he thought the low pressure was a problem, so he adjusted it up in the cab for MORE air pressure, ie released the brakes more. And there was no way for the brakeman to directly communicate with the engineer up front at the time. So due to the inop dynamic brakes, the overweight cars, and the engineer over-riding the brakeman's air pressure adjustment, it all added up to catastrophe.
