There ARE differences in tractive effort & gear ratio, especially on camel hump gradients, locos have to struggle hard to get across. On a plain land, service of WAP/WDP/WDG/WDM/WAG will be same & those with highest T.E. & H.P. will be the winners, but on gradients, goods class locos will serve better than passenger class, just because of a different gear ratio than P class locos, which(class G) are meant for hauling heavy freights. Due to the same reason, G class locos are used as bankers. Now this doesn't mean P class locos cannot run on gradients.
Not passenger trains, but dhn allp, rou jat always run packed.
That is because goods based locos are more focused torque rather than peak speed. This is necessary because of the sheer amount of heavy load haulage they do.Speed isn't such a high factor here.
Passengers loco have gear ratios more tuned for high speeds and accelerations, torque doesn't play a very important role here.
And these means that while goods based locos are powerful enough for hauling passenger trains, the same can't be said for passengers loco. Acceleration and top speed means nothing, if you don't have the required high starting torque.

One more reason is there, adra, rnc div don't home passenger locos, so bksc, tata, bndm & even asansol wags come to the rescue. While the wap4s of SRC are directly entering ecor or seldom touching this section, so only WAGs or WDG/Ms from Ptru are running on this route.
this is the truly main reason..of it, rnc dont have locos ,,because allapujha express and Jammu both run fine with wam4 powers that too crossing full hill of Ranchi,,,bokaro to rourkela,,and chopan to rourkela,,it runs fine with wam.
