That's when the windings come off the armature due to centrifugal force.

I knew the term long before I got into the railroad world... My dad is an avid fisherman, and as a learning youngster, I birdsnested many a reel...

I see while I was typing Jayrod gave the technical explanation.

Randy is the loco friction bearing ? I assume yes. And no alignment control yes? And a 20mph speed restriction on a busy main line for @ 80 miles ??? And the UP is considering this ?

Put it on a truck, if it runs build a panel and ramp and run it onto the truck. The engine will arrive on time and it will be cheaper and easier than dealing with the UP.

How many GE 100 ton locomotives have you moved by "just run it up onto the truck"?

This is 100 ton/200,000 lbs. not counting any of the truck weight.

There are very few if any trucks that could handle that weight , using a drive on style of moving. That may work for a small GE 44 or 45 ton, or even a small steam locomotive, but not a 100 ton unit.

I trucked a GE 80 ton. Removed the body from the trucks and still had a super load. The semi and the body weighed in at 182,500 pounds. After weighing the locomotive, we found out that it had extra ballast. There was a steel box under the cab floor which had steel and concrete in it, adding 12,000 to 15,000 pounds of weight.

Many of the later built GE centerbab locomotives have their frames filled with concrete.

I owned a 1962 built GE 50 ton. It had a "V" shaped fabricated frame. To see if it had concrete as ballast, I took a drill and drilled a small hole in the frame, sure enough, it had concrete as ballast.

You are going to need a bigger truck!

Sadly, there is no real easy or cheap way to move this locomotive.

We are moving it 80 miles within the Las Vegas area... UP is suggesting a flat car. We are also investigating a heavy truck. It would be much simpler to load on a truck.

I was involved since you asked in moving a 50 ton GE center cab on a truck, the SP1233 steam engine at 75 tons on a truck and consulted on the McCloud 18 from the McCloud to the Sierra at Oakdale on a truck weight around 100 tons. I have moved passenger cars, cabooses and a lot of heavy machinery all by truck. I have loaded Westinghouse transformers that are much heavier, It only takes more wheels and axles to increase capacity for a load. My point to Randy was as someone who has been involved in car movements of special loads and hearing the horror stories from others as well as my own. I would recommend trucking the engine, it will be much more painless in the long run, and Randy will get it on time.
