@Strummer posted:Probably a lot of us have thought that same thing, especially when looking at 3 rail layouts like Norm's, Dave's etc.
O (1/48) is really the only size/scale where this even comes into play, so I guess my response here would be: maybe there is no "Perfect" 3R track...the closest might be the "original" outside 3rd rail used back in the day...(?)

Living near NY City, can definitely say, outside 3rd rail is Prototypical. Not just on Light Rail, it is used on the "Hudson Line" (former NYC).
