I would say the regular link is WAP1/4 RPM/ED.. Btw AJJ WAP1 is almost extinct.. They have been moved to RPM. Well Nandu... we should consider the most used link as the regular link.. I have spotted this in chennai almost on all days.. and well most of the time it was WAP1.. Never with P7's.. Anyways i consider a GZB P7 a proper offlink for this train.
