I've decided to build a small mining themed micro layout to put into my shop. The size will 24" by 24" square. I haven't fully committed to a track plan yet. I recently purchased a used Bachmann Davenport 0-4-0 Gas Mechanical. It needs a new paint job, but it runs well. I plan to use both types of Bachmann mine carts. I plan to use Atlas Code 100 Track with every other tie removed.
