I have a Max Gray Big Boy that I wish to consider putting it on display on a roller track for stationary operation. Can you people help me find a source for such a project. Thanks.

Micro mart sells them in sets of axels. Make your own. Google o gauge roller display.
I have one for my Big Boy from this company:

They can be used for 2-rail and 3-rail.

This is all in German.
I'll check with Micro MArt
What would be neat is to build a model of the PRR locomotive test plant and run the model on that!
Pretty certain the Pennsy had no 4-8-8-4s so you might need to upscale the basic equipment. 
Still, something loosely modeled after it would be very cool.

This gives me an ideal use for a bunch of 1/2 in. dia. roller bearings I recently purchased. They were intended for future endeavors fabricating a turnable and display bases. Never hurts to find more uses in a variety of projects.

Mine came from JAK machine tool at York years ago.
There is a set by Arduk on eBay
Thanks for the tip, but I'll need two sets of four for the Big Boy, unless I am misunderstanding the set up.
I think Laidoff Sick as a how to video.
OK, I'll try and find it. Thanks.
Interesting video and it does give me an idea and also produces a few more questions. Thanks!!
I think you're making this too hard. I saw a neat idea a few years ago for a stationary rig. Just suspend the train about 1/16" above the rails with a few large screws through the ties holding up the locomotive and tender. Some rubber bumpers on the heads of the screws keep it from scratching and also provide friction to keep it from moving. Wire it up and it' runs with no rollers visible.
Wow, that's an interesting idea! But won't that be too wobbley? These engines are heavy. But this is certainly an easy way to approach it!!!

Neat idea, John …. I assume that at only 1/16" off the track, the center pick-up rollers would still contact the center rail but with no wheels touching track, how would you wire the ground side ?

If you align the supports, it's as steady as a rock. Usually, there are some little depressions or ridges in the frame to help. Believe me, this is way more steady than rollers!

A simple wire to the frame in the rear or under the locomotive gets that job done.

Roy, are you the seller? $199 plus shippng for four roller pairs?
So what about my 2-rail Big Boy as far as wiring it up to run this way? Sure would be cheaper than the rollers.

No. I am not the seller and I have no knowledge of the seller. I merely posted this as an example of what is available.

No problem that I can see. You just have to find the two power connections. One is likely to be the frame, the other is the insulated wheels. Connect that to a wheel wiper.
