"Ever seen a train lay its own track?"

Those who lament the difficult conditions workers faced while building the first transcontinental railroad using manual labor will be cheered by the amazing progress exemplified by this video of a train that lays its own track.

Have seen the same type of train which automatically replaces the old ties and rails with new ones, working on the Philadelphia Main Line. A huge increase in productivity compared with the 19th century and quite amazing to watch!!
