12000 HP Locomotives for Indian Railways

[dray]

@Chanakya's_Chant @gslv mk3 @Ankit Kumar 001 @Rain Man
Do we have a dedicated thread for Dedicated freight corridor on forum.
If not can one of you create one in suitable section, i'll be happy to contribute

You are the best person here for such a thread!

 

[anant_s]

No such thread exists, I would love it if you could create one and contribute! The DFC (and larger DMIC project) is something I try to follow as much as possible so anything you could provide would be very much appreciated.

@gslv mk3
Would you please do the honors.
we can start from UNEP report that studies the feasibility of projects and how Indian Government arrived at idea of what is arguably the biggest infra project for Indian Railways.
i should be ready in a week's time on a small historical perspective of how Freight locomotives were selected on IR.

What？

India still needs foreign assistance and know-how to make a few damn locos？

Perhaps India should consider importing this 11200KW（15000+ HP）200kph locomotive from friendly China？

So far no Chinese company has submitted any bids

Are they not barred from doing so?

I think they are not

@anant_s how much reliable is this?

GE part of news looks correct, however will try to get confirmation.

@anant_s sir, what product would GE and Alstom be submitting for this specific bid?

Hope the French win this thing Americans rarely share tech

 

[Abingdonboy]

Just to be eligible to take part in this competition GE would have to have agreed to full ToT. If i'm not wrong, many of India's current freight trains are built from GE tech @anant_s ?

 

[Ankit Kumar 001]

@Abingdonboy sir its not GE but EMD. Present generation of diesel locomotives being produced are from EMD, US.

@Echo_419 Actually all our diesels in service are having American origins. From ALCOs to EMD.

(Data i'm quoting is from Greg McDonnell's Locomotives: The modern Diesel and electric reference)
Diesel Locomotive
The requirement for Diesel locomotive for DFC was a 4500 & 6000 HP locomotive and both General Electric and General motors Electro motive Divisions are in fray. A total of 700 (4500 HP) and 300 (6000 HP) locomotives are proposed to be procured. For these locomotives a new plant (green field project) is approved at Marhaura in Sasan Bihar. the proposed cost of this plant stands at 2500 crores. the two proposals for the locomotive are as follows:
General Electric
AC6000CW (6,000 HP)
This is a 6000 HP, 4 Stroke V 16 engine equipped with IGBT based traction system. It has a starting traction effort of around 740 KN, close to the electric locomotives proposed for DFC. Maximum speed is around 120 kph.

ES 44AC (4,400 HP)
Evolution Series 4400 HP locomotive, GEVO-12 engine (V-12), with GM 205 alternator. This is one of the most produced and popular locomotive in North America.

General Motors (EMD)
EMD SD90MAC (6,000 HP)
Equipped with GM16V265H, 16 cylinder engine and 6 Siemens motors. The architecture of traction system is almost identical to existing WDG 4 locomotives with IGBT based traction system.

EMD SD70ACe (4,300 HP)
These locos are export versions of older SD70M models and are equipped with 16-710G3C-T2 engines. These locos are compliant with latest emission norms in US.

The history of Indian Diesel locomotives is as follows:
---------------------------------------------------------------------------------------------------------------------------------------------
Locomotive Manufacturer (Country of origin)
---------------------------------------------------------------------------------------------------------------------------------------------
WDM 1 American locomotive Company (ALCO)

WDM 2 ALCO followed by DLW India

WDM 3 Henschel

WDM 3A, B, C, D &F DLW

WDM 4 General Motors EMD

WDM 6&7 DLW

WDP 1 DLW

WDP 2 DLW

(Later Classified WDP 3A)

WDP 4 (B and D variants) GM EMD later DLW

WDG 3 DLW

WDG 4 GM EMD later DLW

WDG 5 Designed by DLW with GM

kindly excuse the poor formatting, i'm not able to correct despite repeated attempts.

@anant_s

Why are we wasting money for a 4500HP locomotive when we are doing good with 4Ds?

And are the 4,300 hp locomotives being offered by EMD better than our present EMDs?

 

[anant_s]

And are the 4,300 hp locomotives being offered by EMD better than our present EMDs?

Yes and while i don't have a document to show, the new 4300 HP locos we are getting have a much higher starting traction effort than existing WDG 4 (Even for same HP). So what that means is that they will be able to pull heavier trains and sustain a higher balancing speed, something that owing to lower axle rating of WDG 4 will require multiple unit operation.

 

[Ankit Kumar 001]

And are they 4 stroke or 2?
