Here's a construction process used in China for long pillar-supported track.[1] That's an useful machine.
I wonder, though, how much time is wasted slowly backing it up to the staging area to pick up each new beam section. Maybe they sometimes use a beam carrying machine to bring more beams to the erecting machine.
Japan seems to prefer to build at ground level outside of cities.
