Hey Guys! Santa brought my 8 year old son an HO scale Bachmann starter set with the EZ track. I've determined that I'm going to build him an under the bed roll out layout for his bedroom, for him and his friends (& me) to play with. He has a couple of manual switches and 5 or 6 cars with his DC loco. This will be on a piece of plywood, framed on the bottom with some cheap plastic casters to allow it to roll under his bed when he's not using it. Which has gotten me fired up about building a permanent layout, leading me to this: I am in the planning stages of building a permanent father and son layout out in our finished out storage shed. I have an "L" shaped space roughly 9' x 9' ranging from 2 1/2' to 3 1/2' in depth. I used the atlas RTS freeware to design an HO plan which would pretty well suit our vision. But, I'm thinking that N scale would be a better size for us, increasing the number of operations, etc. I realize that N scale (at least I think I do) has less detail on the Loco's and rolling stock. My main question is, do the N scale have all the operations of magnetic coupling, uncoupling, switching, DCC & sound, (basically all the bells and whistles) you get with HO or are they size restricted? I've read up on the Kadee knuckle couplers for HO, are they the same for N scale? I've been reading alot of these posts and I know you guys have some pretty elaborate layouts with a bunch of amazing stuff. I want to get to that point someday, but I don't want to get 2/3 of the way into N scale or HO for that matter and discover I've invested in the wrong scale and have to start over. As you can tell, I'm new to this and to be honest quite astonished as to how much can be done, like the multiple elevations, etc. What are your opinions? Pros and Cons? Thanks for your help and ideas... I'll be asking more questions I'm sure.
