#IR's first Dual-Cab Diesel-Electric Freight Locomotive WDG-4D #12681"VIJAY".
------------------------------------------------------
The WDG4D has been developed in conjunction with RDSO and is equivalent to the existing single cab WDG4 (EMD GT46MAC) design. A WDG4D costs Rs147m compared to Rs143·8m for the single cab version, and is 2 m longer at 21·7m. The air-conditioned cabs have TFT screens displaying operating and fault diagnostic information, and an ergonomically-designed control stand and seat with tilting back and lumbar support based on designs used on excavators.

4 500 hp locomotive is powered by a 710 G3B engine, IGBT controlled three-phase traction motors and computerised braking controls. Top speed is 105 km/h, with a maximum of 100 km/h envisaged in revenue service. The WDG4D could also be used to haul passenger trains in emergencies.
The WDG4D shares components with twin-cab passenger locomotives built by DLW, which is expected to simplify the start of series production after successful trials with the prototype.
