This was designed for the Small Layout Design mailing list’s Christmas 2001 competition. The challenge was to build an HO scale layout less than 30 inches long and up to 16 inches deep.
You’re limited to short wheelbase locomotives and rolling stock, but you can’t claim you’ve not got space for a layout any longer!
The layout is based around a double slip and a three-way point, both from Peco. Add a few inches of track off each end and a few low relief buildings and you have a switching puzzle which can keep you occupied for a quick half hour’s shunting.
Carl Arendt put together a version of this plan as a narrow gauge Gn15 layout and published details of how he got on on his website - (now moved here) - take a look around his site anyway as it’s full of inspirational ideas.
