In volume 4 from 2006, this 63 minute DVD contains 4 main features. The first segment is the layout of brad markosky's Midwest central railroad. Brad has an incredible knowledge of modeling skills.

Take note at the ice depot facility that was inspired by the real thing in Yakima Washington for example. A New York central 0-6-0 shunts the ice car in the loading dock.

Just halfway between the 11 & 12 minute mark, the OGR team heads for a 3 rail layout of the Stolfa family. The layout contains realistic structures which was inspired by the older Chicago area.

For power, Alan uses the MTH DCS. Alan also has a Pennsylvania articulated 4-4-6-4 steam locomotive number 6193 with some pacing. The room was built in 1996, and the construction on the layout began in 1997. There are plenty of scratched built bridges on the layout, as well as scratched built buildings.
