My initial design had the Atlanta trackwork mostly focused on the north end and along the aisle. Below is a general view. Backdrops are panels done by Brian Kammerer. The track that traversed the left side of the Car Shed was initially designed as a continuous running for open house visitors. Eventually I removed the bridge to expand the aisle behind Chattanooga beyond the roundhouse.
However, the last panel was pulled in a recent operating session for ease of access. One operator, Andy Estep, suggested connecting that continuous run track as a run around for a loco coming onto that run-around track. Hence, the idea was born! Above, the track to far right was the continuous run connection. I laid a switch on existing track to begin planning the new run-around.
Below, two additional switches are installed. The former continuous run is now the interchange for the Atlanta & West Point RR. The other track you see is marked for the Georgia RR interchange. The operational possibilities have significantly increased including a yard operator position.
