	The Indian locomotive class '''WAG-8''' is a class of 25 [[Volt\|kV]] [[Alternating current\|AC]] [[electric locomotive]]s that was developed in the 1990s by [[Bharat Heavy Electricals Limited]] (BHEL) for [[Indian Railways]]. The model name stands for [[5 ft 6 in gauge railway\|broad gauge (W)]], AC ~~Current~~ (A), ~~Freight~~ traffic (G) ~~engine~~, ~~8th~~ generation (8). ~~They~~ were ~~only~~ prototypes ~~locomotives~~ .

The model name stands for [[5 ft 6 in gauge railway\|broad gauge (W)]], AC current (A), freight/goods traffic (G), eighth-generation (8). Only two units of this class were built, both prototypes.
