Re: Offset Rail Gapping

I wonder about this fascination with gap locations. If you're using an autoreverser it will detect the short when when a wheel hits the first gap, flip the polarity, and everything will be fine. As far as wheels connecting power districts (or track circuit blocks) that will happen as long as the wheelbase of the loco straddles the gap (assuming all wheel pick-up). The gap locations don't make any difference (within reason). Steam locos with pick-up on one side of the loco and the opposite side of the tender will pick up from both sides of the gaps. This is why boosters are bonded. Trying to space the gap so that the lead wheel on the loco hits one gap at the same time as the lead wheel on the tender hits the opposite gap can only work for one type of loco moving in one direction.

Having the gap distance longer than the locomotive should probably be avoided, but shouldn't really cause any problem. See steam loco example above. :)
