How do those of you with a large collection of locomotives choose addresses for your decoders? And more to the point how do you remember them? I don't have either problem with my Bachmann E-Z system. My eight engines (almost) chose their own addresses because I have a B.R. (ex L.M.S.) layout with these engines 2MT, 3F, 4F, 5MT, 6P, 7P, 8F. It is true that I have a 4MT yet to give a decoder, so I will have to assign that to 1 or 9, but wasn't the choice of engines (some several years ago) rather lucky?
