WDG4 - 4000 HP GOODS LOCOMOTIVE

Broad Gauge freight traffic Co-Co diesel electric locomotive with 16 Cylinder 4000 HP engine, AC-AC transmission, microprocessor controlled propulsion and braking with high traction high speed cast steel trucks.

First turned out in 1999 with transfer of technology from General Motor (USA), this locomotive has exceptional fuel efficiency and very low maintenance requirements. It is specifically designed for heavy haul freight traffic requirements of Indian Railways for the 21st Century.
 
The heart of loco Traction Control Converter uses the GTO devices (obsolete technology). Now the IGBT devices, has been introduced from Oct�2006. It is the latest technology and will be cost effective and gives higher reliability.

The locomotive power has been upgraded to 4500 BCV and the first Loco (Loco No 12114) was manufactured in May�07
