Indian locomotive class WAG-9 - WAG-9 is the name of a type of electric locomotive used in India. It is currently the most powerful frieght locomotive in Indian Railways' fleet. It is very similar to WAP-7; the only difference being the gear ratio which makes it suitable for heavy freight operations. In November 1998 CLW started producing these with indigenous components.
