My first attempt at building a roller base.

Nice job Jeff. I did my roller base with Gargraves & used a dremel to cut the track. I have never cut Lionel track.

Looks good Jeff, my only comment is you'll probably regret making the upper level so small if you get a larger tender. Why the upper section on each end?  I settled for a 2-level design as well, but I didn't put an upper section on the front.

I also went "big", my upper track is 15" and the lower level is 30"  It's switchable between 2-rail and 3-rail and also has a detachable uncoupler/unloader control and embedded track.

My first one!

More recently made a smaller one to test single unit diesels.

You guys are great!

I just plop three pieces of track on the bench and set the rollers on that. It takes a minute to get the rollers positioned properly, but the whole thing )minus the track) fits in a parts drawer when I am done.

Of course, my work bench accommodates trains of two different gauges, car radio rebuilding and real car repair, so I cannot specialize too much.

That plus the fact that I tend to be lazy are all factors.
