Reverse Loop w/ new FasTrack O31 curves

Looks like a good plan. 

I've had good luck with reverse loops using Fastrack switches (including O-36).  I estimated that my layout, when all Fastrack, had them operate automatically in anti-derailing mode bout 80,000 times with no failures.  So, when I went to all Atlas track recently, I still used Fastrack switches for my reversing loop Ys, making and fitting transitions. 

I've used O36 and made reverse loops, but I have too many locomotives that won't run on O36 now, much less O31.  Also, you can only reverse short consists, half a dozen cars or so.

That's great!  I was wondering if it would work.

I tried it, the plan works.  The O-31 does not fit together as tightly as the O-36, there is a slight gap between the sections.  The was the same for all ten pieces that I bought, I think it's a byproduct of reducing the radius. 

If space is consideration, you can also make an 031 reverse loop using an 072 turn out that will allow you to reverse trains up to 11 feet long:

Space permitting, you can stretch the size of the loop by adding pairs of straights.  I did this on my layout and can now run longer trains.  Before, my train length was constrained by the size of my turnback loops.

Yep, you can stretch it, but as you say, takes more space.   I guess there is no such thing as a free lunch.

Gentlemen,

   I have used the reverse loops on our layouts for many years, depending on which part of the layout and the space alloted the track size aways differs.  I do not use the FasTrack switches instead I use the old Lionel 022's.  Remember however if you engineer part of your layout, in this manner, it limits which engines and rolling stock you can run on that section of your layout.   Eventually with more space you will engineer reversed loops with the 711 or 072 type switches, to allow the

running of larger engines and rolling stock, without problems.  With little space you must engineer to match the space limitations.

The loop as described above will fit a williams turbine and seven 2400 series coaches with some room to spare - in other words, for all the 0-27 guys who will be the main buyers for this track, most any reasonable consist will fit.
