I started fitting new Atlas track to my BEEPWorld Loop  today ( It's an all-36" curve area of my layout where nothing longer than a BEEP is allowed).  The photo below shows of a track section I made this morning, and a zoom view on it, for a special (okay, crazy) application I am doing there. I made this section out of two Atlas flex track sections, just removing a rail from each and then fitting one back common to both.  I will be mounting this is a few minutes.

Five-rail Atlas Section

The five-rail section will go in the green part of the BEEPWORLD plan shown in the bottom of the two diagrams shown below.  For several years, I operated BEEPWorld configured as in the top diagram: a "dogbone" with switched reversing loops at both ends, twisted over and under itself.  It was/is a very fun configuration (the light gray lines indicate track inside a tunnel).  The lower diagram shows the new BEEPWorld plan.  At the left, I am extending it so that I get room to build a mini Albuquerque type station, but it will still be an over and under reversing loop of sorts, but without switches.  

WHY?  The section shown in green in the lower diagram was a 3% but will be a 4+% slope when rebuilt.  Now, everything on this loop has to run conventional, with no cruise.  Even at 3%, there was a substantial slowing down versus speeding up of trains on this loop as they went up and down.  My first plan was to use separate track sections up and down this time (three rails up, three rails down) and wire them so the up had about 2 to 3 volts more than the down.  But I did not have quite the width to fit them without a lot of work tearing up terrain and scenery.  The five-rail section will be about 3/4 inch narrower - not a lot, but just enough so it will fit.  Besides, its really a weird thing to do.   Only the outer outer rails, so to speak, will be fed power, the "up" rail with about 3 volts more than the "down" rail.  

So that is my excuse, and yes, there are alot of other ways I could have done this, or gotten the voltage boost, but - tis seemed quirky and fun . . . . and, just because . . .

This is so cool, there is a near real world prototype for what I am doing.

 

I say "near" because, strictly speaking, at least as I understand it, my track section is not a pure gauntlet because  on a gauntlet track there is a discrete set of rails for each direction/gauge.  By contrast, on my five-rail section, the "center outer rail" is shared - the train uses it in both directions.  However, I have no doubt that somewhere, someone did this in the real world (it saves the cost and width of that extra rail).  

 

I will have the section laid down in an hour or two and post more pictures.  I have it in plqace but am testing it before screwing it down, etc, right now.
