I think it will be always a debatable issue of extension of this train, Duronto was a successful concept but executed in a wrong way, it should have been more concentrated on U.P., from Lucknow, Allahabad and Varanasi each a duronto to Mumbai and a Duronto to Bengaluru would've solved most of the woes of the state from UP only Allahabad has a duronto to both New Delhi and Mumbai that are running successfully more places in UP like Gorakhpur, Lucknow and Varanasi should have been given, at least from Mumbai. Cities of UP like Varanasi and Allahabad desperately need this type of train to Bengaluru.
