Could someone point me to the exact reason of SF trains like 12304(Poorva) & 12324(NDLS - HWH Exp) getting delayed between Allahabad & Mugalsarai every single day by atleast 3-5 hrs?
Which out of track quality, no. of trains on this route, passenger load, signalling etc. is the main reason for the delay especially in this 160 km section?
