Hello, I really enjoy your program. I do have one problem. I’m working with Bachmann HO scale E-Z Track system. I thought it was me when I did my first layout. I did another layout without the use of 2 switches. It seems that if you use more than 2 the length of one of the tracks is a bit short. I finally did the exact same layout from “Your First Railroad Track Pack” from Bachmann and I can’t get one track linked. I’m 1 1/8” short and there are no tracks they make that can fix this. Thank you for your time.

In both cases, the misfit is caused by the geometry of E-Z track. Unfortunately, it's not easy to make a perfect fit due to the lack of filler track.
In the first example that you attached, the gap appears because the crossovers are 21 1/4 inch long. I've one of them lying here in front of me, and remeasuring it still leaves it at that length!
So, 2 x 21 1/4 = 42 1/2 inches for one side, against 5 x 9 = 45 inches at the other side.
The gap is 2 1/2 inches. Best fit would be the 44513 with a length of 2 1/4. Indeed, it's not perfect.
The second one fits.
The third example cannot fit perfectly either. In principle, a slightly wider curve is required to make it fit 100%. The best thing here is probably to just make use of the natural flexibility of a longer stretch of track and just force it in. In reality, you probably wouldn't even notice the fact that it's not a perfect fit.
To do these things in AnyRail, you need to switch the 'snap dropped parts' option off (Tools/Options/Behavior).
Next, disconnect the track in a couple of places, rotate or shift it just slightly, and drop it into place.
If necessary, set the tolerances slight higher (Tools/Options/Tolerances).

I also think there is something wrong with standard turnout for the EZ track library. From my experience they are made up of a 9" straight piece and a length of a 18" radius curve. The one in the library has a reverse leg curve of over 52" radius and really does cause issues!

Which ones do you mean?
The 44130, 44131, 44561 and 44562 are defined as a 9" straight and a 30 degrees 18" radius curve.
We've all the H0 E-Z track switches in our possession, and all library definitions have been carefully checked with the help of their real counterparts.

My radius calculation was off in my previous post, but if you compare the curved sections of the turnouts with a standard 18" curve they do not match. Making a complete circle from the turnouts yields a 20.5" radius circle not 18". I'm attempting to attach that example.

Ah, I see what you mean.
This is caused by the fact that the curve starts slightly shifted relative to the straight (about 1 11/32"), as the picture shows.
It's like creating a full circle of 18" curves with short pieces of straight in between.

So will this be fixed in a future version?

Hi Scott,
Sorry if it wasn't clear, but the dimensions as given in AnyRail reflect the real part and are 100% correct.
So there's nothing to fix.
David.

Sorry for my confusion, now that I've obtained some of the track in question I see that they are correct. I guess my memory didn't serve me very well when thinking back when I first had a setup made from this track.
Thanks for the quick replies,
Scott

No problem!
Thanks for confirming that the track definitions are correct.
