Railworks America

Stumbled across this tonight.. Interesting stuff. I never, ever knew stuff like this existed. Very odd to see huge trucks equipped with pantographs running under overhead powerlines.

You're right, that was a big "WTF" when I saw the panto-equipped ones...

Most of the buses in San Francisco are powered this way.
