The model name stands for broad gauge (W), AC Current (A), Goods (G) engine, 6th generation (6) First variant (A). They entered service in 1988. A total of six WAG-6A were built at ASEA, Sweden between 1987 and 1988. they were the most powerful locomotives in India until the arrival of the WAG-9 class.
