This was at the recent SGMA layout (which was amazing by the way) at York in April, 2023. These two items are produced by members of the SGMA and are absolutely invaluable if you collect or even try to play with old toy trains.
USA Tracks is probably the best standard gauge track I've ever seen. I've seen tons of this stuff over the years and I've paid for way too much of it. With that said, the USA Track I saw at York is just head and shoulders above anything that has ever been produced by anyone, anywhere. I'm going to be ordering some sections to kick around with some of my standard gauge. If you get a chance to check out the SGMA layout at any event or function, there is a good chance you'll be seeing this track. If there is interest, I'll be glad to ping the owner and SGMA Member, Kirk Lindvig.
Multi-Gauge RaX is also a "best of the best" type of product. The thickness and build of this for displaying trains is just better than anything I've seen. I have a ton of tinplate display track sections and they just are nothing close to MGR. Again, one of the key members of the SGMA is doing this (Wayne Strobel) and he is super-knowledgeable about these. If you are building a train room or just want to display a few trains, this is really a must-have. I would very much like to replace MANY of my sections (which are shoddy in comparison) with MGR's.
The two above items are really important to running trains and being successful collecting them. They are both absolutely world class design and quality. PS The prices, for this kind of quality, are beyond reasonable. Worth every penny!
