Good Morning everyone. Can anybody tell me that why does CLW manufacture WAP-4 Locos even after starting to design WAP-7 Locos ? I have heard that both these AC Electric Locos can't haul long distance 20+ Coach Passenger Trains more than 140 Kmph MPS :-p
.
PS: Do P-4 and P-7 serve different kinds of trains on IR Network based upon their acceleration and speed capabilities ? :-o
