Lionel or O gauge reverse loop

[Anonymous]

May have been answered before, but I haven't found it when searching the posts.

If I make a reverse loop using standard 3 rail track, do I have to insulate or do anything special the way I would with 2 rail HO track? I'm going to be setting up a continuous run track along 90 feet of wall.

This is one of the advantages of 3 rail, no insulators or reverse switches required.
