I am planning on putting a shelf around the perimeter of my son's room, about a foot from the ceiling (we have 10' ceilings).  Is a "G" scale train the best to see from the floor?  I was just going to purchase a Bachmann set, and some extra track, and throw it up there.  Am I getting in over my head?  I have never done this before.  Am I going to have to oil the trains every so often?  Any help or suggestions in getting me started on this project would be greatly appreciated.  Thank you.

I am getting ready to buy the Durango & Silverton - Freight large set.

  I have a couple of questions....Are the large sets "G" scale?  I can't find it anywhere on the box, and I am going to need to buy more track.  Do you know how sharp of a turn the trains can make?  I am planning on putting shelves around my sons room, and I have to figure out the turns.  The room is 14' x 18'.  Thanks a ton......
