We can agree to disagree Bob.
My apprehension to numbering everything sequential is what happens, as has in the past, we add a stall to the roundhouse, car barn, or even the shop (5 tracks, wow..) What would we have to do then? Change each track up one? So the track 6 would become 7, or would the new bay become 4a?
I just think using the building, as we do now, followed by the track number, also as we do now, is the easiest way to have it.
