The bar will be raised further in 2018-19 to 19 km per day, according to an action plan formulated by the public sector behemoth to bolster rail network, Railway Ministry sources said.Laying new tracks, replacing old ones and doubling and tripling of lines are essential to clearing the traffic bottlenecks, said a senior Railway Ministry official.Traffic congestion is becoming a bane for freight movement, railways' major source of earning, with goods trains not getting path on priority basis.Railways is poised to surpass the ambitious target of commissioning 2,500 km broad gauge lines in the current fiscal, 30 per cent more than the last year.
