This is a simple layout that is a lot of fun. With three lanes there is a lot of space for multiple trains running at the same time. The reverse loop permits the inside train to reverse direction. With two WX310 crossovers, any train can be moved toward the inside lane.
This layout is ten feet by four feet. The largest table I have is a 40×40 inch square card table. For this layout, I used two square tables and one 24×48 inch table. To create a smooth surface, I covered all the tables with pieces of peg board.
The tables are all slightly different heights. I use large pieces of cardboard to bring all the surfaces to roughly the same height. Over top of the peg board I spread a couple layers of green felt. It’s not perfect, but it creates a fairly smooth bed for the track. All together, I invested less than $50 in pegboard and green felt. It was worth it.
This layout has three main tracks. The two outside tracks have turnouts.
On the inside is a reverse loop. The blue and red sections of the train are electrically isolated from each other.
Two insolated Unijoiners are located close to the switches for the storage lanes.
This layout took about an hour to set up. It utilizes Kato Unitrack and is all DC. The complete SCARM file can be downloaded here.
