This summer N scale modelers from around the world set up the world's biggest layout in Louisville, KY. The Derby City Express, as it was called, featured a layout of staggering proportions. The exact details can be found here, http://web.mac.com/pauljdowns/2008_N_Scale_Convention/Home.html , but the numbers that I heard at the show were about 700 modules, spread across 50,000 square feet with roughly 100 scale miles of mainline. A run around the layout took about 3 hours. 

I have signed on to Model Railroad Hobbyist as a contributing editor for a column on N Scale subjects. I have started this journal to solicit feedback from N Scale modelers with suggestions on what you would like to see in the column. So if you have an idea or subject that you think needs coverage post it here, or drop me a private email at info@alkemscalemodels.com
