Hmmm.. Thought but didn't things improve from back 2011 to 2017 now when doubling is being commissioned in many parts... Atleast one train could have run over 60kmph avg on mumbai-Madras route.. Must say this trump route has been neglected the most.. No Garib rath, no duronto, no humsafar, no premium, no aggressive train has been introduced on this route... 12163 ko bhi bail gaadi bana diya last kuch saalon mein.. Lets hope aane wale salon mein kuch accha ho
