Guys,I am thinking about building this 2x4 foot layout since I can easily set it up and take it down.I gotta find something to keep me occupied. However I plan on making some changes. 1.Eliminate the bottom crossover crossover and both switches since they have no real reason to be there. 2.Cut the yard from 4 to 3 tracks. 3.Eliminate the engine service track and engine house 4.Use smaller industries and use 2 on each industrial track. Improvements. 1.Use the bottom track as a interchange and run around. After thought. I could leave the bottom cross over and place a industry there. Any thoughts/comments?
