This layout was designed to fit the dimensions of a hollow core door, and uses Kato Unitrack. The track plan is based on the Carolina Central, and fits into a space less than 7x3ft.
This is an old photo of Stone Creek and the I-girder bridge in the background. The bridge has been replaced because the radius was to small for 50 car trains. Stone Creek is still a part of my 24' X 30' NYC Janesville Branch Layout.
