Loco Cab Ride in electromotive diesel locomotive WDP4 leading the Premium Air Conditoned Superfast Express, experience the Short Hood Front diesel engine cab ride with non stop stations skip with honking and signal exchange by both the pilots.

The EMD GT46PAC is a passengerhauling dieselelectric locomotive with AC electric transmission designed by General Motors ElectroMotive Division and built by both GMEMD and under license by Diesel Locomotive Works (DLW) of Varanasi, India for Indian Railways as their classes WDP4, WDP4B and WDP4D. The GT46PAC is a passenger version of the previous Indian Railways EMD GT46MAC freight locomotive. The locomotive has a 16 cylinder 710G3B diesel engine with a maximum speed of 904 RPM. ====================================================== Performance of WDP4B The WDP4B which is a 4,500 hp (3,360 kW)126 t (124 long tons; 139 short tons) weighted loco with a single cab & capable of hauling 24 coach trains at 110–120 km/h (68–75 mph). It has got six traction motors and are CoCo bogie equipped (more similar to WDG4), unlike the original which has a Bo11Bo arrangement with four traction motors. Due to some controversies regarding visibility hindrances faced by loco pilots in driving long hood front, the basic WDP4B model has been modified to dual cab to eliminate any such possibility. Other features of WDP4B and WDP4D are same. The cabs have a slightly wider profiles, to improve visibility. ====================================================== The loco is very fuel efficient and has minimal exhaust emissions unlike ALCO based locomotives, thanks to its 2 stroke high efficiency diesel engine. It is characterized by its loud horn, which can be heard for large distances around, and aircraftlike sound of its running engine. The use of the locomotives "long hood forward" has been criticised because the driver might have difficulty in seeing signals. This criticism has been rejected by Indian Railways. But the solution to this problem is to upgrade all WDP4 and WDP4B models from single cabins to WDP4D models of dual cabins.
