WAG12: India’s Most Powerful Locomotive
WAG12 is a class of electric locomotives that are designed and manufactured by Alstom in collaboration with Indian Railways. They are the most powerful locomotives in India, with a power output of 12,000 horsepower. They are also the fastest freight locomotives in the country, capable of running at a maximum speed of 120 kmph. In this article, we will learn more about the features, specifications and benefits of WAG12 locomotives.
Features and Specifications of WAG12
WAG12 is an acronym for Wide Gauge (W), Alternating Current (A), Goods traffic (G) locomotive-12. The locomotive is based on the Prima T8 platform developed by Alstom for heavy-haul operations. It has a twin Bo-Bo configuration, meaning it has two sections with four axles each. The locomotive is 38.4 meters long, 3.2 meters wide and 4.2 meters high. It weighs 180 tonnes and can haul up to 6,000 tonnes of load.
The locomotive is equipped with six asynchronous traction motors that are nose-suspended and forced-cooled. It has a regenerative braking system that saves energy and reduces carbon emissions. It also has an advanced communication system that allows the driver to communicate with the control center and other trains. The locomotive has a modular design that allows easy maintenance and repair.
The locomotive has various safety features such as automatic doors, smoke alarms, CCTV cameras, fire detection and suppression system, anti-skid system and anti-collision system. It also has various comfort features such as air-conditioning, ergonomic seats, LED lighting, WiFi infotainment system and large windows.
