12000 HP Locomotives for Indian Railways

Who would you personally want to win? GE or GM?
From railways point of view GM EMD, mainly because of a huge fleet of 3 phase Diesels (WDG 4 and upcoming WDG 5) which are GM EMD locos, so for railways that won't be major transition in terms of staff training, upkeep etc.

here are two pics from my personal collections of WDG 4 and WDG 4D

Bro,what's the present status of "Bhim"?I mean the last time i saw it in Bengal,it was being used as a goods train engine.So,is there any plan to convert it into a passenger engine??

i suppose you are referring to WDG 5.
As on now 3 locos of this class (50001,50002 & 50003) have been manufactured and all are homed at Sabarmati diesel shed in Gujarat.
This loco is pretty similar to EMD's SD80MAC and is rated at 5500 HP.
there is an RDSO report on a 6000 HP loco and its analysis tells that 6000 HP or thereabouts is required for a 22 coach self generating coach train to run at 150-160 kph. so theoretically these locos could be modified. however the problem is that all HHP diesels are freight locos that are geared for 120 kph max. Besides as most high speed tracks are electrified in India, i'm not sure where these can be used other than Konkan Railways.
therefore the chances of getting a 5000+ hp high speed diesel aren't very bright IMHO.
 
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?:D

We know very well how to took the help of Germany in building high speed rail network. We can build any damn thing on our own but it is not always advisable to spend money on R & D in some technology which is available very cheaply world wide.
 

New Delhi: The government’s plans to both create investment in Bihar ahead of the elections as well as create more competition in the Railways got a boost with French major Alstom emerging as the lowest bidder (L1 Bidder) for the production of Electric Locomotives in Madhepura in Bihar, India.

Sources say the bid was for under INR 30 Crore each, taking the size of the contract to INR 25,000 Crore over 10 years. Apart from manufacturing 80 Locomotives a year, the contract envisages maintenance for the locomotives for a period of 12 years. Setting up the factory is likely to cost around INR 4,000-5,000 crore.

The bid is much lower than what the Railways had envisaged. In 2009, for instance, the Railways internal estimate was that a bid of around Rs 28 crore would be acceptable. The government has been trying to set up the factory since 2005, but has been unsuccessful so far. In 2008, when the final groundwork was done and the bids called, it was opined that the projects were scuttled by some vested interests in the Railways on grounds that there were too few bidders.

Three global companies – Alstom, Bombardier and Siemens had been shortlisted for the financial bid which opened on Monday. The financial bid for the Marhowra Diesel Locomotive plant is going to open today with GE and EMD being the shortlisted candidates. The Marhora plant is expected to manufacture about 1,000 diesel locomotives in ten years, that is 100 locomotives annually.

looks great !

Sir Diesel Locomotives have their own advantages over Electric locomotives.
Not 100% Railway lines van be electrified, like ghats and mountains.We will need diesels for them . Also diesels are immune to any electrical failure in railway grid.
Also some regions near ports see double decker freight services, which can only be hauled by diesels.
 
hi @anant_s why we are going for too much diesel engine when GOI convert all the railway line to electric.
sudhirji,
as much as we would like to see that, in practice its next to impossible. Railways usually put up a report indicating how much traffic moves on a section. now in railway planning they refer to a term called throughput which roughly translates as how much load can you move in a given time. now consider you want to move 100 tons of load between point A and B in say 1 day. now you cn do that by either employing 2 50 ton trains moving fast or a single slow moving 100 ton train.
ideally a single train option is better owing to a. lower capital and running cost and b. on a section it is easier to move s single train.
now going back to traction railways are trying to employ high HP locos to move more load on a single train while keeping axle load constraint in mind. As things stand now with our traction, electrics offer better solution owing to faster acceleration for same HP.
so on saturated lines where higher throughput is the only solution to accommodate more traffic, railways are going for electrification.
second thing is electric tarif. IR is paying around 4 ruppee per unit on average which is very high cost. so electrification on tracks that donot earn much revenue, diesels are only economic solution.
