I talked to Eric Moe this evening to get an idea how the G Scale units are made and what power truck he uses. Most everything is 3D printed so they are plastic. Truck frames are also 3D printed and the flywheel is functional. I told him I was thinking about converting to Std Gauge. He did not see it as an easy task because of his truck design, but he likes the idea. He will do a study to see if he can make wider truck frames keeping the scale staggered design. They are 1/32 scale, but the truck width and pilot height would most likely have to be altered for our purpose. He understand they would need a rectifier or? and 3rd rail pick up. He hopes to get back to me in the 1st quarter of 2020 with his input.
If you have any interest, send him an email so he will know there is a bit of interest.
