Tamilnadu vs Purushottam Express!!
For those, who always feel Purushottam get overtaken by Tamilnadu, if both depart simultaneously from NDLS & Purushottam slows down to change track to get over Main Line towards GZB:
Purushottam crossed Hirangaon (218 KM covered), while TN (no doubt its legendary) has crossed Farah (160 KM covered)!!
PS: NDLS-CNB is more congested along with Caution run till GZB!!
