WAG-7 is the name of a type of electric locomotive used in India. It is a very powerful locomotive in Indian Railways' fleet. Built by Chittaranjan Locomotive Works to RDSO specifications, these represent the next indigenous design step up from the WAG-5 locomotives. Used primarily for goods haulage, these locos have a Co-Co wheel arrangement with high-adhesion bogies.
