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. The first one 'NAVYUG' (translated 'New Era') was flagged off on Nov. 14.
