The WAG-6 locomotives, introduced in the late 1980s, were among the most powerful in Indian Railways, boasting a power output of 6,200 hp. Built by Hitachi and ASEA, these locomotives were designed to handle heavy freight on steep gradients.
Despite their impressive capabilities, they were discontinued due to the advent of more advanced three-phase AC technology, which offered better efficiency and lower maintenance.
Additionally, the limited number of units produced (only 12) made it economically unviable to maintain them. The WAG-9 class eventually replaced them, offering superior performance and reliability.
