Welcome to DIESEL TRACTION

A revolution was taking place on INDIAN RAILWAYS in the post Independence days.the good old steam engines-the puffing,snorting black iron horses gradually gave way to sleel,smooth running workhorse ,over the days since launching the first locomotive in 1964,DIESEL LOCOMOTIVE WORKS VARANASI has dedicated over 3500 locos to the nation.It is the 3rd largest diesel locomotive manufacturer in the world and the largest in public sector.It is also the largest diesel loco builder in the whole of Asia.

                                   

 

What is more,DLW  was manufacturing diesel locomotives largely to only threee designs in the past,lately it turned out the following significantly different and improved designs of locomotives to cater to the changing traffic needs.

------->2600 HP FUEL EFFICIENT and eco-friendly locos.

--------->3100 HP HIGHER HORSE POWER LOCOS

------------>2300 HP LIGHT WEIGHT INTER CITY EXPRESS LOCOS.

-------------->3100 HP HEAVY GOODS TRAIN LOCOS.

---------------->3400 HP HIGH HORSE POWER LOCOS

----------------->4000 HP GM LOCO STATE OF ART

 

The site will be featuring addons and downloads for all classes of "DIESEL LOCOMOTIVES"  startin from WDM1 TO WDP4 including the power sounds,which will be featured in the sound section and of course lots of miscellaneous and much more surprises on your way.Enjoy and happy railroading

CAUTION NOTE:statutory warning for msts diesel loco drivers don't exceed the speed limits as these locos are designed for very high speeds ranging from 2000-5000 km/hr(just kidddinggggggggg!!!!!!!!!!!!!!).

      WDM2C ERNAKULAM 14049(FRONT CAB)

      SPECIFICATIONS/SALIENT FEATURES

    • These 3100hp locos are more powerful versions of the WDM-2. The first one was delivered on August 22, 1994. A single WDM-2C could haul a 21-coach passenger train, something that required two of the older WDM-2's. The WDM-2C / WDM-3A also has a rated top speed of 120km/h, and has the same power-pack as the WDG-2 and WDP-2 locos. Early units were air-braked but lately many have been provided dual-braking capability. Dynamic brakes are also provided. The loco has a single cab.
      Gear ratio 65:18 as with the WDM-2. All recent units have a square profile, but a few early versions have a rounded appearance. Starting in [11/02], even higher powered units (3300hp) have been turned out by DLW, Varanasi, and DCW (DMW), Patiala -- all recent WDM-3A are of 3300hp power rating.

     GM

    WDG4 

    SPECIFICATIONS/SALIENT FEATURES

      These are GM's GT46MAC models. First units were imported in 1999 (13 fully built, 8 in kit form). Now [4/02] DLW has begun local production; 3 have been built and a further 25 or so were built in 2002. As of [1/06] 60+ units have been built.

    The loco shed at Hubli has been modified to handle these; initially all will be based at Hubli and will be used to haul mineral ore freight from Bellary or Hospet to Vasco da Gama.

    The locos are rated at 4000hp and use 3-phase AC traction motors. They can start a load of 58 BOXN wagons on a 1 in 150 grade and have a balancing speed of 85km/h for such a load on level track. Max. speed is 100km/h. They can be MU'd with up to 4 units operating in tandem. Gear ratio 85:16. Axle load 21 tonnes. They have an evaporation-bath-cooled converter system, and the SIBAS 16 traction control system. The locos also have slip-control mechanisms.

    They are expected to have lower maintenance costs, as they need to return to the home shed only once in 90 days instead of every 7-10 days as with the earlier diesels. Fuel costs are also about 20% lower than with the WDM-2. [1/05] Earlier plans to home more of these at Golden Rock seem to have been dropped; instead more are expected to go to the northeast (Siliguri? New Alipurduar?).

     

     
    • Builders: GM, DLW
    • Engine: GM-EMD 16-710 G3B, 4000hp, with EMD 'G' turbocharger. WW PGR governor. Unit fuel injection, centrifugal pump as with WDP-2, cooling and fan as in WDP-2.
    • Transmission: Electric with TA-17-CA6A alternator, 900rpm, 2200V AC / 3000V DC, 1600A AC, 2100A DC.
    • Wheelsets: Co-Co bogies
    • Starting TE:55t at 41% adhesion.
    • Length over buffer beams: 19964mm
    • Distance between bogies: 13888mm (? or 13666mm?)
    • Weight: 128t
    • Fuel tank capacity: 6000l

    WDM3D

       higher-powered version of the basic WDM-2C (WDM-3A) class, these locos have a 3300hp powerpack, with available traction power of 2925hp. The engine is an enhanced version of the 16-cylinder Alco 251C model. (It's not clear why the class is 'WDM-3D' which would imply 3400hp -- perhaps it was intended to be of 3400hp, and later units of the class may attain that with further enhancements.) Max. speed 160km/h. Fabricated (welded) Alco High-Adhesion Co-Co bogies. Starting TE is 36036kgf (353kN). Dual braking systems.

    Left hand drive, WDG-3A style High Adhesion bogies, air cylinder under footboard, WDP-4 style fuel tanks, engine doors like WDP-4, marker lights outside cabin doors, electronic horn. Improved bogies with stem type vertical and lateral dampers in place of 'eye' type for easier maintenance. High capacity buffers. Components and auxiliaries improved with the aim of making the duty schedule longer between maintenance visits to the shed. Fuel tank capacity 6000l, engine oil sump capacity 1210l.

    The WDM-3D is the result of a concerted effort by DLW to incorporate some of the best features of the GM/EMD locomotives (WDP-4/WDG-4) into the proven Alco base technology with which DLW has enormous experience. The WDM-3D uses General Electric's 'Bright Star' microprocessor control system to monitor and control various engine parameters, to detect wheel slip, and to supply power in a phased manner to the traction motors under slipping conditions. An oil cooler is provided in this loco, a first for the Alco-based models produced in India. The cab in the first units of this class is a normal metal one, but later units are expected to feature a fibre-glass cab as seen in the WDP-4 (e.g., #20012). (This will result in the dynamic brake resistor grid being moved to behind the cab.) The control desk will also be changed to be similar to that of the WDP-4.

    The first one was built in July, 2003, numbered #11101. Launch livery deep blue with cream stripes, but has possibly been repainted very soon after. Spotted with damaged sandboxes in December 2003 at Bangalore. Maker's plate read 'DM-3D-001, July 2003'. The first few units (five, [11/04]) are all homed at Krishnarajapuram.

     Old class name WDM-2C, new class name WDM-3A.) These 3100hp locos are more powerful versions of the WDM-2. The first one was delivered on August 22, 1994.

    WDS6

      Heavy-haul shunters made in large numbers for industrial concerns as well as for IR, starting in 1975. These locos consist of the YDM-4 powerpack (6-cylinder 4-stroke inline Alco engine, turbo-supercharged) placed on WDM-2 frames. Same bogies as the WDM-2, WAM-4, WCAM-1 locos (Alco cast asymmetric trimount bogies). 1200/1350hp net (1400hp gross). Max. speed 62.5km/h. Several of them have a so-called 'creep control' system which allows them to be operated at a sustained speed of between 1 to 7 km/h for hauling special or heavy loads.

    The first ten were numbered 19459-19468 but later renumbered as they were all allocated to public-sector industrial concerns. Many of the later units built for IR (as opposed to the earlier ones which went to the public-sector concerns in large numbers), numbered 36000 and above, are classed WDS-6R. A few locos of a variant design classified WDS-6SL were sent to Sri Lanka (Puttalam Cement Co.).

     
    • Builders: DLW
    • Engine: Alco 251D-6, 6 cylinder
    • Transmission: Electric
    • Wheelsets: Alco asymmetric cast Co-Co trimount bogies.
    • Axle load: 21 tons.
