I'm posting this here, because from what I've seen, there are not many 2 rail offerings in the Buy/Sell Forum. I hope this is OK.
I was recently experimenting with 2 rail wheels on my 3 rail layout just to see how well they might work. It was a very interesting experiment as they actually worked quite well, even going through 3 rail Ross switches and frogs. Even so, I've decided to stick with the 3 rail wheel sets and i need to find a home for the 3 sets of brand new, in the package 2 rail trucks I have.
2 packs of MTH roller bearing trucks
1 pack of Atlas O trucks with the new, thinner side frames.
They were 20$ each I'll let somebody have 'em for 12$ each.
