The train which was running as Tata/Bokaro Madras got extended to Alleppey in 1991. So you can imagine that it has taken almost 3 decades for it to be finally separated and run as dedicated rakes !!! Of course that time demand and rush was not much as it is now. Finally railways took a very good decision. Better late than never . Now eastern India ( Jharkhand/ Northern parts of Orissa) get daily two trains to South India ( AP,TN & KL)
