Walt,
I read your minimum curve size and rushed to come and see! I am thinking of purchasing a 2014 Christmas Pioneer Zephyr set but am perplexed when I saw that it runs on 072 curve track. I am ready to purchase it for a Christmas Train show in December. I better measure my curves first, huh?
Too much money to end up in a smashed heap on the concrete floor don't you think?
After all, this is not the Adam's Family! I am not Gomez Adams!
Best of luck!
Mike Maurice
