Alright, so this is a totally futuristic train. I realized that since Yuva can go from HWH to MGS at just 7.40 hours, why not we have a Gatimaan which goes from Howrah to MGS with stoppages at Dhanbad and Gaya? Please flag this train if the concept is correctly implemented and do let me know your views as comments below.
Update: Extended to BSB with halt at ASN
