P-5s are much more capable than what most Rajdhanis and most tracks can handle brother :)
Just because a WAP-7 came after the WAP-5 does not guarantee it's superiority!
Rather barring it's higher acceleration figures, a WAP-7 is rather inferior to a WAP-5 in almost every manner!
WAP-7 is actually a redesigned goods loco (WAG-9) while the P-5 is a true passenger locomotive...

WAP-4 for this Rajdhani is not a good option
in day time it gets tracks empty only 3-4 trains are ahead of it one of them is MB which OT by 12424 after CNB
i travelled in all three trains
WAP-4 is good for Shiv ganga due to congestion only 110 mps and only CNB halt
while SK also bcoz of two halts in whole journey and congestion
get tracks cleared due to RAJ gang
