... topic: 1196 Newbie- needing to understand Handedness, switches and crossings much better. posted: 11 Aug 2010 02:19 from: grog_polymer I went back to the companion and had a look at the switch and crossing sections under real track. 1920_101644_010000000.jpg What confused me is the "End of turnout curve" because I had expected the turnout to continue to curve after the entry straight. So I went back to tors and had a look at the radii and centres of entry, exit, branch and the turnout itself. I was surprised that the branch track was was not at the substitution radius but rather all track elements shared a common track centre line radius but that the branch line just had an appropriate offset for the centre of its curvature. I also played around with the entry straight length. I was also trying to get a grip on why a left or right had turnout mattered when many of the negative turnouts appear very "Y" like and I could not understand why it mattered. If I understand correctly now: a turnout ...
