Now the Concern is though Kalka Shatabdi has HOG WAP-7 as it's "Permanent Link", still "EOG/Generator Car" used in this Train. Not ONLY this Train we have seen many AC Trains hauled by HOG(Head On Generation) WAP-7 still using "EOG/Generator Car". As per CLW "HOG WAP-7" is used to "Supply Power To the Train which is the Function of EOG". Now if EOGs are used in AC Trains in spite of hauling the Train by HOG WAP-7 Loco then what is the utility of HOG WAP-7?
Recently One Brand New HOG WAP-7 has been allotted and sent to RPM Shed of SR.(RPM WAP-7 30426)
IR and CLW should seriously think about this Issue. If they use HOG WAP-7 then EOGs should NOT be used as the Function of EOGs are performed by the Loco.
Otherwise STOP producing HOG WAP-7. Running AC Trains with EOGs as usual. But don't "Misuse" the HOG Loco by using EOG in the Trains hauled by HOG WAP-7.
I don't think "HOG" System of WAP-7 30277 is used in case of 12005/12006 or the HOG System of WAP-7 30277 is NOT working properly. If used or working Properly then EOGs won't be used in 12005/12006.
After all HOG Loco is meant for avoiding EOGs in Full AC Trains which result in reduction in Pollution by Diesel EOG and Save Fuel Cost.
