Here's some photos from some operating sessions at Harley Smith's house. Harley's basement contains his Ohio Northern layout, easily one of the largest home layouts I've ever visited and the largest that I've had the privilege of operating on. Here's a map of the layout.
We'll start out the session by following an Ohio Northern train, pulled by two SD7's, around the railroad.
As more people arrive and start running trains, the action on the railroad begins to heat up.
Harley's layout has a facinating branch which is the source of the stone traffic that operates on the railroad. Known as the Valley Line, it leaves the Ohio Northern main at Hillside Junction Yard, crosses the main again at Valley Crossing, and makes its way to Valley City, where a large stone loader is located. Empties are pushed up the branch by the Hillside Junction yard crew, and the yard crew at Valley City is responsible for picking up the hoppers and loading them with stone. The following photos demonstrate the process:
