I think Jonathan's idea at the top is a good one. As for this sub-forum, I would rename it the "Modelling in Three-Rail Scale" forum. That was the original idea when it started as a sub-forum about a dozen years ago. It was a place to talk about pushing farther the trend toward more scale equipment, such as by fixing pilots and using more scale-like (typically Kadee) couplers. The idea was to encourage that trend, encourage greater knowledge of the prototype, and for "Three-Rail Scalers" in turn to encourage the manufacturers toward even more prototype fidelity. ("My Premier diesel's smoke unit doesn't work" wasn't really a Three-Rail Scale topic). Sunset Third Rail is the manufacturer that comes closest to those ideals, and it's natural to talk about Scott's products here. But we have Lionel, MTH, and Atlas O sub-forums, so why not have a separate Sunset/Third Rail forum too?
