Level crossings

[Oldun]

  Does anyone make an electrically operated gated (not a boom type) level crossing, or
          am I going to have to make my own

Heathcoat Electronics sell a module for switching the
gates automatically, but I think you have to make the mechanical bits using servos and cranks. There's a video on Youtube,looks like a lot of palaver, perhaps there's a simpler way or other product.
