I've constructed the 9V point centerline geometry through trial and error. What I came up wasn't very intuitive, so it's probably wrong. (I don't think there's an LDraw representation of the point yet, although it looks like Ludo Soete is working on (...) (22 years ago, 8-Feb-03, to lugnet.trains, lugnet.cad.dat.parts)
 
  Re: 9V point geometry
 
(...) ... After some conversation with Ludo Soete, I created a geometric construction to prove that the 9V point curve can be created from the same circle radius as the 9V track, without any straight sections. I did this by modeling this Track (...) (22 years ago, 10-Feb-03, to lugnet.trains, lugnet.cad.dat.parts)
