Analysis of information sources in references of the Wikipedia article "Ballastless track" in English language version.
NCRTC has selected "Austrian Slab Track System" for track on main line.
From Japanese experience, it has been learnt that although initial construction cost of slab track is about 1.3 times higher compared to conventional ballasted track, if we consider life cycle cost in the long run, slab track seems to win the race.
