Watch the video here in 1080p www.youtube.com/watch?v=csl0iEtBFkc N scale custom model train layout. This layout were calling "Kato City" It has a dogbone track plan that raises in elevation and drops back down. The inside track is for Portram, and a branch line serving an oil tank. The outside is double tracked with a spur so three different trains can run. I will have a video for this layout on My Youtube in the next few days... entitled "Kato City"
