Ka ho bhabua.... this Gaya - Mughalsarai section may turn fit for 140-150 Kmph after becoming a 5-Track (Existing 3+ 2
#EDFC Tracks) one. I feel that IR should run a Dhanbad - Varanasi Shatabdi at such speeds between DOS and MGS :-)
.
PS: IR can even think of running a Shatabdi between KOAA and GAYA with stoppages at Durgapur, Asansol, Dhanbad and Parasnath. Even such a train can rap the DOS-MGS Stretch at 140-150 Kmph MPS :-D
