I presently have a 1/43 track that measures 4 1/2' x 11 1/2' and want to run an Tyco HO scale track above it, either with the same footprint or slightly smaller. Problem is that I have no idea how to do this. Does anyone have any ideas on stacking seperate tracks above one another. I want to install lighting under the top track to give adequate lighting to the bottom one and I don't want any braces in the front to interfere with the view of the bottom track. I was thinking of mounting 1 by 4s equal spacing along the back of the bottom track, and attaching brackets for the top track to mount to. Then running cable to each corner of the top track from the ceiling to adequately hold it up. Any ideas or input would be appreciated and if you've done this type of thing and have pictures, all the better. I have the lumber, have the track, just don't have the space any other way.
