One of the most beautiful locos of IR i.e. GMO WAG 9H # 31086 a.k.a. Dr. SILVER One Of my Favorite Locomotive Of Indian Railways...!! Gomoh WAG9 H 31086 Also Called as Dr Silver. Waited almost Three Years for this moment finally got it at Janai Road.!! It is the only loco In this Livery...i.e Maroon Instead of Green..!! Central Railways Ajni Transferred to East Central Railway Gomoh Shed is a unique livery loco it features some remote diagnostics and tracking features via cellular networks. About WAG 9 WAG-9 is the name of a type of electric locomotive used in India. It is currently the most powerful frieght locomotive in Indian Railways fleet. It is very similar to WAP-7; the only difference being the gear ratio which makes it suitable for heavy freight operations. In November 1998, CLW started producing these with indigenous components. The first one, NAVYUG (translated, New Era), was flagged off on Nov. 14. Like the WAP-5 units, they have GTO thyristor converters and 3-phase asynchronous motors. This locomotive is referred to as the Heavy Haul freight locomotive of the Indian Railways. This locomotive was conceived owing to the extreme growth in the rail freight transportation sector. The growth in this sector is considered to be of great importance in the growth of the economy of India. This need had arisen the need for more electrification and electric locomotives in India. Around 60-65% of the freight haulage of the Indian Railways takes place on the electrified section of the Golden Quadrilateral (Indian Railways) & diagonals (which account for 25% of the route). These routes are highly busy routes, so clearance is a necessity. This power give it a great sectional clearance ability. Thus these locomotives are important for the Indian Railways. First 22 units were imported from Adtranz(ABB). Of these, first 6 were fully assembled and rest were in kit from. Again in the kit form, 7 were completely knocked down and rest partially assembled. Manufacture of the traction motors at CLW started on Jan. 11, 1999. Rated at 6125hp each, two units can haul 4500t trains on gradients of 1:60. A single unit can start a 4700t load (58 BOXN wagons) on a gradient of 1:180 (some CLW documents say 1:150), a great improvement over the WAG-5/WAG-7 locos that were restricted to hauling such loads in sections of gradients 1:200 or less (this was the primary motivation behind the induction of the 3-phase technology for freight locos). Total weight 123t. Continuous power at wheel rims 4500kW (6000hp). Starting TE 520kN; continuous TE 325kN. They also generally have better adhesion than the WAG-5/WAG-7 locos, partly because of the computerized slip control. Rated top speed is 100km/h. Axles Co-Co. Pantograph has a double collector bar in the Adtranz-built units; the CLW-built units use a pantograph with a single collector pan, as in other AC electrics. Multiple unit operation possible; although the locomotive designs provide for several units to be MUd together, IR restricts these to just two units being coupled at a time because of dynamic loading restrictions on most bridges. Auxiliaries from ABB, Landert, Behr, Howden Safanco, etc. Regenerative brakes provide about 260kN of braking effort. About WAG 9 H WAG-9H also has different application software than WAG-9. 1st WAG-9H was commissioned on 30/6/2000. #30130 homed at Gomoh(GMO) shed(Gomoh) was this prototype then rebuilt back to standard WAG-9 in 2002 A 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).
