tim5055 Posted October 16, 2015 Report Posted October 16, 2015 They are amazing machines. For the last year I lived in the DC area they used two similar horizontal cranes installing the train "bridges" for the Washington Metro extension through the Tysons Corner area of McLean, VA. They basically set one or two sections of the elevated track each day for miles. http://www.dullesmetro.com/project-stat ... ns-corner/
