The WAG-9H was a heavier version (by 12 tonnes) of the WAG-9; the higher adhesive weight makes it suitable for hauling heavier freight rakes: 58-wagon BOXN rake, ~4,700 tonnes, on a 1:150 grade. In 2000, it was undergoing trials on the Ujjain - Nagda section. Later, the loco was converted back to a plain WAG-9. Photo by Sujeet Mishra, 2000.
