Tru,
If you are referring to the trains that guy made, they were in the same size as the old electric trains used to be which was quite a bit larger that the Ho and other size. I remember I had one that you had to stick a key into the side of the engine and wind it up. Sure wish I still had that one.
Then at Arden Fair in Sacramento they used to have a model show every year and they had a big hobby shop there. The winner one year was the most realistic battle scene I have ever scene and that person made everything with his own machine shop.I remember a big German Tiger tank coming over a slight rise in the ground sand there were bodies and parts of bodies with blood on the tracks and there were bodies and blood all over the big battle field he had made. Blown up artillery pieces, crashed planes and everything your would expect at a big World War 11 Battle. I talked to him and he had an electric motor in the tank that he could run by remote and it would fire shells that were made of plastic. I used to go to that place a lot as there were some of the most incredible models of everything you could think of there and they all had to be at least 80% hand made. I marvel at the skill and patience of the people who used to display their work there.
