Even though I posted what is your answer above in another topic, I will repeat it here. UP ran a set of Light Engines to the site yestrday as symbol WSPSPW 25 to get the equipment. Yesterday evening, they ran back to Sparks and the CAD/Dispatcher treated the move like the President of the Railroad was on it, they even put an Eastbound Freight in one of the passing tracks (Can't remember what one) to keep this train on the main. Although I don't have any technical data, it appeared that they ran it at Passenger Train Speed, not to exceed 70 MPH! Of course, there were no people onboad this move.
