WAP 7 loco failures are less in comparison with wap 5's....

Something happened in this section not with this train as the most puntual ones like 12059 Kota-NZM Janshatabdi Exp arrived NZM 1:39 hrs late at 14:09..Barring winters,i have never seen Janshatabdi getting delayed to such extent.

Any 3 phase loco can breakdown easily.
however, WAP-7/WAP-5 have good number of failure rates.
let CLW attach the IGBT inside, them, and the WAP-7's failure rate will b tend to decrease.

Agree 3 phase loco's tend to fail more often....
P4 are the backbones of IR.....

Fully agreed. WDP4B/4D locos also have 3-phase AC traction motors. But they rarely fail. CLW needs to manufacture WAP5i/7i locos.
In case of WAP5, which has GTO inverters (one inverter per bogie), modifying with IGBT (one inverter per axle + software tweaks) can reduce the risk of wheel-slip significantly.
