Thanks for all the advice, and keep it coming
I've located someone who runs a store that sells this stuff. I'm in the process of getting him to put a package together now.

Very good info...thank you.

Ok, I'm getting it...smaller distance between the wheels to make navigating the tighter radius turns easier. What about track? Should I use the designated 15" radius track or is it possible to do it with Flex Track/
Thanks for the help!

Ok...guess that's why I couldn't find any with the 15" radius. So if you want to try to get the 15" radius, you would have to purchase the track separately, correct? Is there a special kind of track / cars I need to buy in order to get the smaller radius and make sure the cars will work properly on the track?
My problem is I am trying to incorporate this into a Christmas Village display and the "N" scale is too small. I really need HO, or TT (TT would be perfect) but It would be great if I can keep the radius at 15". I don't especially care if I have to use smaller cars/loco's...although I don't really know much about how you tell the sizes while shopping online? Unless someone knows where I can get TT scale???
Thanks for the replies and help

Hey guys! Been reading/lurking for a while. I am just about to get started with my very first model train...but as a newbie, I could use some help. For my first layout, I would like to go with HO scale, and have a track radius of no more than 15"...30" diameter. I have limited space and this would be perfect. If it is a little more, I could handle it though. I was also thinking about the total track to be 30" X about 90". Just want to start with an oval. Again, a little bit different size smaller or bigger wouldn't really matter.
Also, can I get this size of a track layout in any kind of a kit, or do you have to buy it individually? Is there a certain kind of track that would enable me to have the 15' radius...and so on. I would prefer to buy it in a starter kit, but am not sure it is available like that. I am very new to all this so please be gentle with me.

Thanks!
