Densha de go controller as power controller

[Bjorn]

I already have seen Densha de go controller modifications to be used as a power controller, but I don't remember a plug and play box.

Maybe that's a gadget and use a all in one controller is a better solution, but the link between model train and video games speaks to me. 🙂

As I as understand it support PS 1 and 2 controllers and USB ones.
