I pulled out my LGB trains again this year, and as usual, it's sparked yet another resurgence in interest. I hopped on ebay to see what was available, and I was surprised to see that "real" LGB track seems to be going for a lot more money than other brands of G-scale track. Why is this? Is there anything about it that makes it tangibly better than compatible track made by other companies? Or is it just a matter of the original track being rare, and people want it because it's scarce and original?
