A WDS-6 locomotive basically consists of a YDM-4 powerpack (a 6-cylinder, 4-stroke, inline, turbo-supercharged ALCo engine) mounted on a WDM-2 body frame. Beginning in 1975, these were initially manufactured solely by BLW, Varanasi , but later, the Parel Workshop started building them using CKD (completely-knocked-down) kits provided by DLW.
They entered service on 18 July 1995. A total of 1,164 WDG-3A units were built between 1994 and 2015 at BLW, Varanasi with a few units being produced by Diesel Loco Modernisation Works (DLMW) and Parel Workshop. It is the dedicated freight version of the highly successful WDM-2 and shares the same engine and horsepower rating with WDM-3A.
DLW again built WDM-3A variant locomotives, during 2005–2006, in the road number range 14144-14167 which were classified as WDM-3B due to their difference in bogie design from classic ALCo asymmetrical trimount to HAHS design which was employed in WDG2 and later WDM-3D classes too. Most of the WDM-B were later converted to WDM-3D.
The WDM-2 locomotives from serial numbers around 17788 to 17890 were fitted with full-width short hoods with the intention of improving visibility for drivers. [27] These are unofficially termed 'Jumbos' by crew and rail fans. [28] WDM-2 #17722 and #17748 are rumored to be the prototypes of the jumbo class but differ slightly from other Jumbos.
The Indian locomotive class WDM-3 was a type of diesel-hydraulic locomotive that was developed by Henschel for Indian Railways in 1962. The model name "WDM-3" stood for broad gauge (W), Diesel (D), Mixed traffic (M) engine, 3rd generation (3). These locomotives were put into service between 1970 and 1971, and a total of eight were built between ...
The engine is classified WDM-3D though it outputs only 3300 hp and not 3400 hp as the name should suggest. They entered service in 2003. A total of 590+ WDM-3D were built at Banaras Locomotive Works (BLW), Varanasi between 2003 and 2016. The WDM-3D is one of the most successful locomotives of Indian Railways serving both passenger and freight ...
[1] 44 units produced until February 2001 (Indian Railway road number 15501-15544) had dual cab forward design different from other classes of locos built by DLW (WDM-2, WDM-3A, WDG-3A and WDP-1). [2] These new locomotives have control stand similar to many electric locomotives. They are the re-geared versions of the WDM-3A. This was IR's ...
Lean-burn gas engines are almost always turbocharged, resulting in high power and torque figures not achievable with stoichiometric engines due to high combustion temperatures. Heavy duty gas engines may employ precombustion chambers in the cylinder head. A lean gas and air mixture is first highly compressed in the main chamber by the piston.
