    I doubt anyone designs track from scratch. The various rail authorities use standards. The John Holland Country Rail Network standard is http://www.jhrcrn.com.au/media/2169/crn-cs-210-v1-3.pdf The ARTC equivalent is https://extranet.artc.com.au/docs/eng/track-civil/procedures/track-geo/Section5.pdf?260716
    These standards are living examples of "the devil is in the details." Frightenly complicated.

    Pity that they don't seem to mention turnouts.

    In NSW the set of tangential turnouts is (CMIIAW) something like:

    1:7.5 about 150m radius?
    1:8.25
    1:9
    1:10.5 about 300m radius?
    1:12
    1:15
    1:18
    The V-crossings can be curved or straight.
