True that. But WAP-7 would be comfortable on the L.P.s I think. A lot of HWH WAP-4s are certified for 130-140 kmph use, but they only work on trains which ahve less halts. Not for Poorva which has so many halts between DHN and MGS. Still, it does extremely well.
130 kmph clearance should be given in HWH to ASN Quadruple section atleast.
