... went through the 2008 revision to the 2001 "Improvisation" tutorial on Symmetrical& Turnouts and thought I did quite well. I even think I understand most of what I did. However, in testing the two branch lines, I found that they are not perfectly symmetrical. The screen shot, below, shows my S4/P4 Symmetrical Y with a piece of straight track joined to the end of each branch line. I then looked at the rotation angle of each straight track and renamed those templates with the rotation angle. 2480_290100_250000000.png As you can see one is 5.05 degrees above horizontal and the other is 6.40 degrees below horizontal.

Is this amount of error impossible to avoid or did I mess something up? My next question will be what happens when I try to create a #3 Y for my Timesaver trackplan? Will ...
