Here is a link to an website with many good ideas for planning layouts with lots of operation that fit small spaces. Tom http://www.wymann.info/ShuntingPuzzles/small-layouts.html#Basic switch list
That's a good link for puzzle-type layouts. For a wider variety of small layouts, also have a look at: http://www.carendt.us/ and http://www.carendt.us/articles/index.html
A shamless self-plug here, but a good site for layout designs... some small, some not. I love it when people post their designs to the site... http://www.layoutdepot.com Peter
