WAG–9HWAG-9HA heavier variant of the WAG-9 (12t extra ballast, welded at four locations in the machine room behind the cabs -- a design proposed by CLW and approved by AdTranz) and consequently higher TE. Everything else was just as in the WAG-9 class, except for some application software changes. This was expected to be used in haul heavy freights (58 BOXN wagons, 4700t) without the need for multiple units even on incline sections of 1:150. The ballasting raised the starting TE from 460kN to 520kN. Continuous TE 325kN. The first (and only, as it turned out) of this class was was commissioned on June 30, 2000. This locomotive, #30130, 'Navshakti', then homed at Gomoh, cleared trials but because of concerns about the weight, did not enter regular service. It was deballasted and converted to a plain WAG-9 by mid-2002. That was the only unit of this class ever tried out. The class was intended for MU operation (2 units). Trivia: This reclassified loco, now [11/04] at the Ajni shed, still sports its variant livery with two white stripes instead of the single yellow stripe characteristic of other WAG-9 locos.
