This one taking 7 years ain't so off the mark.With the trains moving at around 160km/h,bends/curves and inclinations/declinations will have to be dealt with and that's why it takes a bit longer than it would take building the narrow gauge[1,000mm] line. For such speeds to be achieved,the new standard gauge[1,435mm] line will have to use continuous welded rail (CWR),also known as ribbon rails.This allows a smooth ride at higher speeds.The CWR with very few or no joints at all,it's construction takes more time than a jointed track.Maintenance of is minimal,the track is strong with less friction. Just coz we haven't done it in 100 years doesn't mean we can't. Negativity kills everything,let's try doing with less,much less.
