Minimum radius = 2nd radius

 

This plan offers a development of the 'Oban' theme, with a continuous run and an inner loop allowing two trains to alternate. This plan was developed from the original Port Rush plan by Kebang on the FreeTrackPlans forum, with the possibility of a central divider making for 'two layouts in one'. I envisaged the bottom right corner as a dockside section, with the internal siding serving a small station. A variety of industrial buildings including coal sheds and a timber yard complete the scene.
