railroad.wikisort.org - TrainThe EMD GT50AC or WDG-5 a class of heavy haul Diesel-electric locomotive built by Banaras Locomotive Works, Varanasi in collaboration with Electro-Motive Diesel. At a rated power output of 5,500 horsepower (4,100 kW), it is the second most powerful diesel locomotive class in Indian Railways, just out-powered by the 6,000 horsepower (4,500 kW) WDG-6G. Derived from the EMD SD80MAC, it was meant as a direct upgrade to the WDG-4 GT46MAC (SD70MAC derivative).The locomotive or the series is named Bheem, after the strong Pandav brother from epic of Mahabharat. The loco has an EMD 20N-710G3B-EC 20 cylinder engine of the EMD SD80MAC and an AC-AC transmission. Since the loco has been developed by introducing a v20-710 prime mover and replacing the conventional v16 in the WDG4 GT46MAC locomotive, the model was re-designated by adding 4 to the predecessor model, ie, GT-46 became GT-50 (46 + 4 = 50), owing to the increase in number of cylinders in the engine by 4, ie, from 16 to 20. Development of this locomotive is one of the Best Examples of Atma-Nirbhar Bharat. This loco was unfortunately stopped only with 7 units due to the Fuel Inefficiency of the v20-710 powerpack, the same reason why even the Original SD80MAC were made less in number, and were finally Scrapped Off.

Die WDG-5, Herstellerbezeichnung EMD GT50AC, ist eine Großdiesellokomotive der Indian Railways mit elektrischer Kraftübertragung in Drehstromtechnik. Sie wurde von den Diesel Locomotive Works (DLW) in Zusammenarbeit mit der Research Design and Standards Organisation (RDSO), der Forschungs- und Entwicklungsabteilung von Indian Railways, entwickelt. Die Arbeiten wurden von General Motors Electro-Motive Division (GM EMD) unterstützt.[1] Von der Baureihe wurden zwischen 2012 und 2017 nur sieben Stück gebaut, die im schweren Güterverkehr eingesetzt werden. Die Baureihen-Bezeichnung setzt sich aus W für wide ‚Breitspur‘, D für Diesel, G für goods ‚Güter‘ für Güterzuglokomotive und der 5 hinter dem Bindestrich, die für eine Lokomotive mit einer Leistung zwischen 5000 und 6000 PS steht, zusammen.[2]
