Thanks GG, Paul and Joe. Sounds like I should go with the 18" even tho the 15" might work. And now that I have dimensions to work with ie. 18X2 + 2, I can get a board to place on top of the table. Do you guys recommend the EZ fit tracks?

The transformer, engine and cars are Bachmann but from what i've read they don't make 15" curves and i read something abt. the train being too long to take any smaller radius curves but i don't know anything abt model trains and thought some one here could help.

Hi there,
We have a ho scale EMD GP-18 diesel engine and a HO and N power pack item# 6607. These are over 15 yrs old. What is the smallest track the train can run on and which track items do i need to purchase? I looked at the thortrains.net site and am thinking that I cannot set it up on a 2'X4' tabletop that i was planning to do. Can you verify? It used to be under our tree when the kids were little. Thanks for your help.
