The model name stands for broad gauge (W), AC Current (A), Goods (G) engine, 6th generation (6) First variant (A). They entered service in 1988. A total of 6 WAG-6A were built at ASEA, Sweden between 1987 and 1988. they were the most powerful locomotives in India until the arrival of the WAG-9 class.These locomotives are now withdrawn from service with 1 unit earmarked for preservation.Table of Contents       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4History[edit]Specification[edit]Locomotive shed[edit]See also[edit]References[edit]External links[edit]History[edit]The history of WAG-6A begins in early 1980s with the aim of addressing the shortcomings of the previous WAG-1, WAG-2, WAG-3, WAG-4 and WAG-5 classes and remove steam locomotives from IR by a target date of 1990.[1] The WAG-5 were a great successes but these locomotives were based on 1960s technology and fast became underpowered for the expanding Indian railways. So Indian Railways decided to look for a new locomotive.[2] At that time (1980s) Thyristor controller was vastly used by locomotive in many European rail networks while 3 Phase AC technology was still in its infancy. So the ministry of railways floated a tender for a 6000HP locomotive with Thyristor control. The following responses were received:ASEA submitted their model with 6000\u00a0hp with Bo-Bo-Bo bogies and Thyristor chopper control.Hitachi submitted their model with 6000\u00a0hp with Bo-Bo-Bo bogies and Thyristor chopper controlHitachi also submitted their model with 6000\u00a0hp with Co-Co- bogies and Thyristor chopper controlEach company submitted their prototypes and Indian Railways designated these prototypes as the WAG-6A class WAG-6B class and WAG-6C class respectively.[3] IR ordered 6 of each class and these were delivered in 1988.[4]Specification[edit]Manufacturer: ASEA ( WAG 6A )Build dates: 1988\u201389Wheel arrangement: Bo-Bo-BoTraction Motors: ASEA make (WAG-6A), L3 M 450\u20132.
