Early railway tracks were constructed mostly as ballasted railway tracks. The speed of the trains was low so the ballasted tracks have been performing well. However, as the speed of trains became higher the use of more efficient railway tracks was sought after. That led in the 1970s to the first application of ballastless track. … Read more
