George,
Yes the spacing between the rails for No. 1 gauge is 1-3/4" vs 2-1/8" for Standard gauge. While no one is making 1 gauge tinplate track here in the US to my knowledge, vintage 1 gauge track made by Ives, Maerklin and Bing can sometimes be found. The new 1 gauge track in my photos and the video below came from Europe. This video shows my Electoy set in operation. The locomotives are usually found not in operating condition with blown apart motor commutators. The locos are difficult to disassemble and repair. It took me a while and a lot of effort, but I got this loco running again with an assist from the Motor Doctor, who repaired the commutator.
