What do you mean by a overrated TT? Does this term has any existence over IRI? 12306 aur iske properties me koi fark hai kya? Both are LHB so even this has caliber to run at 78kmph avg. Rajdhani tag dedene se coaches me koi atma nahi aajti.. late hona completely depends upon DNR division. So overrated ya to aap samjhaiye sir warna mat kaha kijiye.. as is tarah ka koi term kisi lhb train ke liye valid nahi hai.
