Are India's Railway engines indigenous?

[TimeToScoot]

Being a technology enthusiast, I was wondering if the engines that run our trains are indigenous. Can someone pour some light on this?

 

[narcon]

Any doubt?
If so, what is that doubt?
They are not imported.
Have a made in Tag.
And exported.

Is the technology indigenous or licensed?

Yes they are indigenous.
@gslv mk3 will help you more here.

In 60' or 70's we license produced them but all the engines we use now are result of Indigenous technology.

For ex. see this monster......

Yes they are Indigenous. Old engines(3 decades back) were licenced produced but all new engines are Indigenously developed and built.

Thanks guys. Very informative. Any information regarding the use of Kaveri engines to power our railways? Which engine is being used currently?

 

[JohnyD]

train engines are not rocket or jet engines...even we have now learned to make rocket engines.....India is one of the oldest operators of train system...I don’t think we still import any engines for our trains...but yes, we have capacity crunch and lack sophistication hence recently we imported passenger train coaches from Germany..But you know, this sophisticated German coaches though airy and spacious, couldn’t bare the load and caused frequent break-downs in service…In fact, German learned from our trains that have been running for many decades with minimal failures…

That will never materialise,that was just to extract more funds from gov.

There are many types of engines(according to there power capacity)......


Passenger locomotives

• WDP 1 (Bo-Bo bogies. 80 tons weight. Rated speed of 140 kmph. 12 cylinder engine. 2300 hp. Built by DLW in 1970. Homed at Vijayawada and Tughlakabad sheds only.
• WDP 2 (New class name WDP 3A. Dedicated passenger diesel locomotive. Entered service in 1998. Max speed 140kmph. Built by DLW. 29.25 tons of tractive effort. 3100 hp)[5]
• WDP 3 (This locomotives are actually prototypes of the class WDP 1 and never entered serial production. Designed in 1996 by DLW. 2300 hp. Co-Co bogies. )
  
  
• WDP 4 (EMD (former GM-EMD) GT46PAC, fundamentally a passenger version of the WDG 4 (GT46MAC). 4000 hp)
• WDP 4B (EMD (former GM-EMD) GT46PAC, An improved version of the WDP 4, this is a more powerful version and has 6 traction motors, just like the WDG 4. Also comes with wider cabin to aid visibility and minor exterior design changes.As of now,serial production of the single cab locomotives has been stopped. 4500 hp)
• WDP 4D (EMD (former GM-EMD) GT46PAC, This is basically a WDP 4B with twin cabs. Minor changes were made to the locomotive to facilitate the addition of a second cabin. This locomotive comes with LCD instrument display and toilet for the drivers. Has entered serial production and regular service. 4500 hp

Goods locomotives

• WDG 2 (New class name WDG 3A. These class is actually a technically upgraded form of WDM 2. Max speed 100kmph. Built by DLW)
• WDG 3B, WDG 3C, WDG 3D (Technical upgraded forms of WDG 2 or WDG 3A. WDG 3B and WDG 3C are rebuilt to WDG 3A. WDG 3C is rated at 3330 hp.)[6]
• WDG 4 (Dedicated goods locomotives. These are General motors' GT46MAC models. First units were imported in 1999. They are numbered from #12000 upward till #12999 and #70000 upwards.[7] Local production started on 2002. 4000-4500 hp)
• WDG 4D (Technical variant of WDG4 with dual cabs. IGBT. Max speed 105kmph restricted to 100kmph. Air conditioned cabs. First dual cab freight dedicated diesel engine in India)[8]
• WDG 5 (Another Freight dedicated Locomotive developed by Diesel Locomotive Works and Supported by Electro Motive Diesels. First unit was rolled out from DLW on 25 February 2012. They are numbered from #50001 upward. Rated at 5500 hp. Equipped with Fire Control System, TFT Display and Driver's Toilet.)Loco is still under trials in DLW, Varanasi. The locomotive/series is named 'BHEEM', after the strong Pandav brother from epic of Mahabharat.

Shunting locomotives (also known as switching engines)

• WDS 1 (First widely deployed and successful diesel locomotives used in India. Imported in 1944-45. currently out of service. 386 hp)
• WDS 2 (o-C-o bogies. 8 cylinder engine. Homed at Central Railway. Max speed 54 kmph. Built by Kraus Maffei in 1954-55. 440 hp. 15420kgf of tractive effort)
• WDS 3 (All locomotives of this class were rebuilt and reclassified as WDS 4C in 1976-78. 618 hp. 17100kgf of tractive effort. Built in 1961)
• WDS 4,WDS 4A,WDS 4B,WDS 4D (Designed by Chittaranjan Locomotive Works. 600-700 hp. C bogies. Built between 1968-97.)
• WDS 4C (Rebuilt by CLW, WDS 3 locos as mentioned above. 700 hp. 18000kgf tractive effort. C bogies. Out of service. Max speed 65kmph.)
• WDS 5 (Some of these locomotives are used for industrial shunting. A few are used on Indian Railways. Rated at 1065 hp)
• WDS 6 (Heavy-haul shunters made in large numbers for industrial concerns as well as for Indian Railways Rated at 1200/1350 hp)
• WDS 6R, WDS 6SL and WDS 6AD (Technical variants of WDS 6. WDS6SL is exported to Sri Lanka. WDS6AD has a max speed of 50 kmph and a 6 cylinder engine.)[9]
• WDS 8 (Only five of these were made by CLW, and all were transferred to steel works 800 hp. Max speed 35kmph. 22000kgf tractive effort)

Passenger locomotives

• WAP 1 (Designed by Chittaranjan locomotive works in 1980 for the Kolkata-Delhi Rajdhani Express. A very successful class. 3900 hp)
• WAP 2 (Decommissioned in late 1980s. Similar to WAM2 & 3. 4 built. Also had Flexicoil Mark -ll bogies. 2910 hp. Only 4 units built)
• WAP 3 (Rebuilt to WAP-1. Similar to WAP-1. Approximated speed of 160 kmph restricted to 145 kmph. 5 Built since 1987.)
• WAP 4 (Upgraded from WAP 1 for higher loads by Chittaranjan locomotive works in 1994. One of the most successful locomotives in India. Very powerful class. 5350 hp)
• WAP 5 (Imported in 1995 from Switzerland and used on premier express trains. 5450 hp)
• WAP 6 (Out of service. Max speed 170 kmph. 16 built by Chittaranjan Locomotive Works in 1997. 5350 hp.)
• WAP 7 (Same design as WAG 9 with modified gear ratio. Highly powerful class. 6350 hp. Max speed 205 kmph. Built by CLW since 2000)[13]
• WAP 7D (Technical variant of WAP 7. A proposed design. IGBT. Lighter than WAP 7. The 'D' would probably stand for dual brakes. Likely to have 7000 hp).

Interesting. Why don't we have bullet train technology yet considering we built these indigenous engines long long ago?

Because that is not economically feasible in a poor country like India.

We may have bullet trains in future.

What's the harm in developing the technology? Once developed we also need to keep improving it. Poor country we're but if we can afford aircraft carriers, nuclear power plants and submarines why not invest in critical technology areas?
