If wishes were horses I would have a huge 2 rail layout on O Scale. The fact remains that while 0 scale 2 rail has undergone a huge revival in recent years, it's still a rich man's or lucky bachelor's hobby. The space required is just insane, to do it right. When the Max Grays came out HO was reigning supreme. The only O scale kits were highly labor intensive craftsmen kits and the couplers by and large were dummy. Contrast that with what you can buy off the shelf from Atlas. Today I believe the 3 railers represent simply lazy O scalers. We can still run our childhood trains but the entertainment value of today's O locos is just outstanding. Sound, smoke.... Great! So you cannot compare the poor sales of those Max Grays with where O gauge is today - both scale and 3 rail which compliment each other as we see here a loco built to both systems.
