Kyon chalate ho isko...har 1-2 week pe cancel karna padta hai...koi importance heen nahee hai...rajdhani ke baad kisi train ki impotance honi chahiye toh woh iski...lekin halat toh dekho...local passenger train ke jaisa...superfast toh dur ki baat hai...I think railway ko ek system ready karni chahiye...agar koi train 3hrs se late ho...toh passenger ko kuch pause wapas milne chahiye...obviously its very vague...but a model should be developed...
