Congratulations;
I am associated with GE Swtiching locomotives of various capacities, right from 150HP hp 1320 hp, used in our steel plant. These are 66″ gauge, mostly twin power pack, expect 150 hp,diesel electric shunting loco using DC drive. Can you suggest retro fit kit/hybrid to improve fuel efficiency.

As an intermediate step, separate battery helper locomotives could be built, or converted from old locos, to work in multiple with existing unmodified diesel locos. The old traction motors would be left in place on the helper to charge the batteries on deceleration and provide additional traction on acceleration. The extra weight. even if it\’s 150 tons, would be marginal on a heavy freight train and a positive factor in traction terms.

Folks, have any of you looked at the price of diesel lately? Sure the railroads want to save fuel, because it\’s money to them pure and simple. These engines have been diesel electric since the late thirties with few exceptions and of course steam power. Nobody has ever called them hybrids before that I know of, they have always been diesel-electric. The locomotive is PURELY electric but carries it\’s own generating plant on board powered by the DIESEL engine or prime-mover. Some of you said right when you mentioned the pollution being made somewhere else for pure elelctric locomotives. These evolution hybrids will make a huge difference by using this regenerative idea. True, it\’s not a new idea, but battery technology hasn\’t been there on this scale before. I say let\’s stop picking this to pieces and call it a good thing and forget it. We\’re saving pollution, there will be less demand for FUEL overall as a nation keeping our prices down, and the RR\’s will save bucks and that\’s good for our economy as a whole. LET US REMEMBER OR LEARN, the Union Pacific RR alone is the WORLD\’S LARGEST CONSUMER OF DIESEL FUEL, BIGGER THAN THE US NAVY! If they can save 15% with these engines, think about the total ramifications. Thanks boys and girls. DH

Think yourselves lucky that you still have a locomotive building company in your country and willing to invest in new technology. We here in the UK have lost all of our rail building industry to overseas companies, mainly due to lack of investment in R&D. As many of your bloggers have rightly commented, it is not just about GE’s claims for improved efficiency but the massive amounts of road traffic that is removed by using rail. In the States you tend to use large freight trains and even more congestion should be taken from the roads. Here in the UK rail is finally catching on again after years of under investment, but I believe that massive subsidies should be given to get freight traffic off roads. This would be a great starting point in restoring this planet’s ecological balance. We can’t go on pumping carbon monoxide, NO & NOx into this atmosphere without disastrous effect.

With regards to those that push the positives of the electric rail systems, remember the massive thermodynamic losses involved in all power plants! Even nuke stations have their environmental costs such as uranium mining and transportation costs as well as the cost of ‘clean up’. It may be more efficient to use these diesels in many cases. Well Done GE, I say!

I thank you guys at GE for the development of the EVO locomotive. I have been inside of one of these locomotives and I am quite impressed with the perforance and functionality of the display screens. I am a die hard railfan, and my e mail address takes after one of your AC6000CW locomotives that were made for CSX. It is one of the three with the GE Diversity In Motion decals on the side. Keep up the good work GE, and keep them coming.

Fuel cells will, ultimately make an even bigger difference. If GE had paid more attention to their inherited IPR in the ’90s instead of internal politics and installed an intelligent CEO, they would now be streets ahead in that struggling technology. Ironically, it will be a molten salt fuel cell (MCFC) that will best match heavy traction applications. There are two advanced versions, an American one mainly for static installations (and shipping) and a German one for static and locomotive applications – it is being developed by an offshoot of the Daimler-Chrysler axis.

On the question:
“The problem is that for something as heavy as a train you need _very big_ batteries to make a small difference in efficiency. I wonder if the savings in fuel offset the cost of the batteries.”

… if it didn’t offset the cost of the batteries, then there wouldn’t be a fuel savings of 15%.

Interesting 50% cut in emissions and 15% cut in fuel consumption… how do these beasts compare to other locomotives elsewhere in the world though?

Electric locomotives are not necessarily cleaner than diesels. The power source for an electric locomotive can be coal, nuclear, or a gas burning plant. The pollution isn’t with the locomotive in this case, but the pollution is still being created somewhere.

The whole money vs. environment thing has to stop. People keep saying that “this technology costs too much compared to what we have now”. Well, what good is your money going to be when there isn’t a planet to spend it on? Much better for us to spend money now and try to fix the problem than to keep holding on to our money and staying in our rut of using oil only to find that it’s too late and way too expensive a few years from now to fix the problem.

And yes, diesels are dirty and they pollute. But one double stack container train can take two hundred trucks off the road using only one high horsepower locomotive. Anything that can take two hundred trucks off the road has got to be an improvement.

No, GHamito, your standard diesel-electric loco does not have traction batteries (starting batteries are another matter). The electric system is used because it improves traction control and eliminates wear elements like clutches; energy from dynamic braking is dumped to resistor banks and dissipated as heat, which eliminates wear on mechanical brakes.

[...] is an interesting article on Inhabit about a new train from General Electric that is utilizing hybrid technology to decrease fuel [...]

Sounds pretty good, if you don’t know that the diesel engine in a train are only used to produce electricity, not running the train.

If you do know this, it’s very old news. Adding a Battery doesn’t really make it better, but it’s on hell of a good marketing pitch.

What about biodiesel fuel instead of using petroleum based diesel? That would be the FIRST step. Run those bad boys on peanut or soybean oil as the inventor of the Diesel engine intended.
