Initially, the track ran between two stations. I was reluctant
to modify and add foreign technique. The tracks were isolated in
fields that received power from several NXT mindstorms. When I
expanded with a third station, I scrapped insulation in favor of
rectifier diodes at each end. The track now consists of two
commuters that receive power from a central NXT. I also added
signals relay so they get individual power.
