Give it a break dude,fact is fact and we are not selling any product here,so you've got to let it go.There is a reason why trains such as (fastest train) bpl shat,lko shat,fastest superfast(bpl express),bct rajdhani are hauled by wap 5.
No other loco touches 150 kmph but wap-5 while hauling BPL shat. in agra-delhi stretch,it is a known fact.Wap-7 are not even allowed to cross 140.Wap 5 can go up to 160.
If p-7 was faster than sbc raj and mas rajdhani would have easily been allowed to cross 150 in agc-ndls...
more... section as they have even lesser stoppages and fact is they are not even fastest rajdhani,by the way fastest rajdhani bct raj. is again hauled by p-5!!
and to top it off fastest speed achieved by p-5 185 in trial runs while p.7 could only come at 177.
