The topic of vertical curves has been generating a lot of discussion lately, with a variety of standards being proposed -- both with and without experiential or computational justification. The purpose of this page is to list and discuss the various standards that various groups and individual modelers have established, along with the scale, gauge, and type of equipment used. Of particular interest will be designs that did not work for some reason. Please feel free to add your own experiences here, so long as there is enough data for it to be compared.
