WAG is a code given by Indian Railways to a series of electric locomotives, run in India. W is for broad gauge, A is for AC traction and G is for goods duty. They are the most powerful engines in the country yet.

WAG 8
Variants
WAG 8
Specification
Build date: 1996
Wheel arrangement: Co-Co
This is an experimental class of which only one or two were built by BHEL in 1996. They are similar in appearance to the WCAM-2 locos. Power output is similar to the WAG-7 at 5000 hp. There is thyristor chopper control of the DC motors. The class probably shared some components with the WCAM-3 which BHEL was building at the time. They are thought to have Flexicoil Mark IV hi-adhesion bogies.
