WAP-5 is mentioned as the 'Mislink' by an official site

right. Both WAP-5 and WAP-7 are suitable locos for Hybrid LHB while WAP4 is not (its needs to be upgraded).
Further more, The Hybrid LHB Duronto via WR gets BRC/TKD WAP5/7 while those via CR get WAP7 only.

Restriction by BSL division of CR.
Similar restriction is being imposed on WAP4 locos as well.

Wap4 too is not preferred now. It's nothing personal. They want smooth operations hence are doing so
Thanks for the update.
This looks rather hypocritical though. For the conditions in this situation, any loco could have had wheel slip. It is puzzling as to how they concluded that WAP4/5 are not suitable on these sections.

Seeing as to how the P7 too is facing similar issues in rainy conditions (and in those two cases posted above, on milder gradients and in one case only a 19 coach load), it is puzzling as to how CR concluded that it is a problem with the locos. At least these two incidents definitely do not show any smooth operations. Particularly, in the second incident, the loco was an IGBT loco, which is supposed to have even better wheel slip control.
Also SCR operates 24 coach trains on the SC-KZJ section (which has a lot of frequent gradients) with WAP4 locos and as far as I know, they have never issued any such restriction. And in fact,...
