Yup, Possible! But i don't think any superfast train deserves to get overtaken by premium trains!!
For express, passenger trains, it's fine but not for superfast though..
Mega congestion at DDU creates difficulties for SF trains like - ANVT-SRC, Garba, Parasnath, Pratap, Ananya, etc which are forced to run at DDU- 2:28/2:38 slot!!
A time will come when DDU will not have...
more... any slot left with it.. 24/7 Super Duper Busy station because of heavy traffic from (Varanasi, Prayagraj, Gaya, Patna)
