I confess I did not use any modeling software for design or for control. I searched for model grilles that were the approximate scale size, and sketched an approximate idea before putting it together with Plastruct girders and sheets that I had on hand.
I also explored various turnout control machines (and the possibility of manual control) before settling on the Peco Smartswitches, which offer a very fine degree of programmable control with a separate control unit, that then can be set and left alone. I didn't realize how big of a field there is in modeling applications for servo control, including model airplanes and cars. The components of the Peco Smartswitches are actually made by a Taiwanese company that sells a range of servo control components to hobbyists. These servos can also be used for animations like working gates, moving equipment, etc.
And just like the real extenders, if they are not retracted as the train leaves, there will indeed be damage! 😁
