about their experience with WAP-4 & WAP-7 and collect their views
They have told that though P-7 is the latest coaching loco with many advance features still we opt for P-4 for the following
***** Cab heating factor is more in P-7
**** In Rainy Season wheel slipping is a crucial factor for P-7
***** As P-7 is a fully computerised Loco so you have to gain a good knowledge to handle it.....
But they told that P-7 is the advanced coaching loco and future of our railways but P-4 is still very comfortable to a ohuge class of Loco Drivers....
