Reply to "2 rail track that takes Lionel"

I was hesitant to explain my approach as purists will shudder.

Here goes.

I am considering replacing the rollers on engines, tenders, passenger cars, cabooses with sliders (tapped to accept the rods that hold the rollers).

Then I can use a Marklin - style pickup (their method gave me the idea).  Blackened screws in the ties would replace the center rail.

Thanks to all who posted - Ross & Gargraves will be my sources.
