Station update: cool machines
They are finishing up the new tracks at Union Station. Laying track is interesting--first a deep trench, then rock ballast; the ties (sleepers in the UK) are adjusted first by hand with long poles and a tape measure, and then the long rails are welded together to create continuous rail. Finally, these wild machines run along and dig in and push rock around. Maybe a railfan will tell us what they are doing.
