This plan was inspired by the track arrangement in Troy, Alabama where the CSX and Conecuh Valley interchange. Until a few years ago, these lines actually crossed at grade. The diamonds were replaced by two turnouts. In this plan, the mainline trains travels clockwise around the loop. The inner loop track is the interchange with the short line and crosses the mainline at the crossing at the bottom of the picture. The branchline engine is parked at the lower right. In a typical day's run, it crosses the mainline, picks up cars from the interchange track, and then switches the industries on the left side. The plan is drawn for N scale, 36" X 72" using Kato Unitrack. There's plenty of room for scenery, buildings, and more spurs.
