Hybrid locomotives.
- Thread starter jadebullet
- Start date
Don't want to stir the manure.. but 1st: In a Honda Civic a battery would cost you about $1,200, but they have 150K miles warranty, so who cares? and if you do a "Google" on Hybrid locomotives you can see that GE is working on it. Are they just dreaming? or is it a reality? well, may be it works: Time will tell.
now THAT is total coolness. three of them now, at least, appearently. i wonder if anyone's working on one for trainz?

Evolution Hybrid
Um just from what I read the batteries are charged up by the heat of the brakes just look at the sides of the the fuel tanks. The process of converting heat in to electricity is similar to solar panels by 10%.:hehe:

With the battery/diesel hybrid, lets say that a diesel powered unit would need to be 4000hp to get a train over the hills from point A to point B, and that the loco needs 8th notch to get started and to get over those hills, but it only averages 4th notch for the whole trip, with a hybrid you would only need a 2000hp diesel running at its most efficient revs all the time, this would mean in 2nd notch it would be using half of the diesels power for traction and half for charging the batteries, in 4th notch it would be using the total power of the diesel with no charging or battery use, in 5th notch and over it will be using the total power of the diesel plus battery power.
Another saving, besides regenerative braking charging the batteries, is that if the batteries are fully charged and it is still going downhill a 2000hp diesel uses less fuel idling than a 4000hp one
Also the engineer could shut down the diesel when he is close enough to his destination to get there on batteries alone, provided there is time to recharge the batteries at the destination, this would depend on the loco roster.

Perhaps in practical terms hybrids still haven't reached maturity, but I believe we will see a lot more forms of hybrid power in the future.
A number of european tourist cities are using hybrid buses in the city centres. Even formula one racing has embraced hybrid technology.
On paper it makes an awful lot of sense, and the basics of it are exactly as Pommie has outlined. You take the "average" power requirements of a given mode of transportation, and use a clean burning, efficient engine running at it's most fuel economical setting to produce only that quantity of power on a constant basis (plus a little for loses obviously). When power is not required or the power requirements are below the average the extra energy is stored. When power requirements exceed the average, the excess is recovered from the storage device.

I've heard Norfolk Southern put out an engine with something near 1,000 batteries in it..forget where they go in the engine, what about where they go once dead?

Hi Woody
I'm assuming your talking about the BP4, an electric locomotive with 1500 batteries. Quite an interesting loco, not sure about the charging of dead batteries though. However it does recharge during dynamic braking.

Yes, I just read an article in Trains magazine. It's built on the frame of a GP38, and it's loco # is 999. It's called "BP-4"... it's experimental. It has 1500 HP.It uses a lead acid storage system made up of 1080 12-volt. It's pretty much only for switching, I guess because if it failed on the mainline in the middle of nowhere it could be bad. It doesn't even produce exhaust!
Somebody mentioned how the dynamic brakes recharge... it does through a system made by Brookville Equipment. I guess they won't release any details. It uses the energy for tractive effort. The batteries are monitored and controlled to keep safety and maximum battery life. When the batteries are fully charged it can operate three 8 hour shifts without recharging. There's no onboard generator.
By the way this info is taken from Trains magazine, none of it was copy or pasted. I reworded it somewhat but some sentences might be the same, so just know that I take no credit for the info.

Remember when locomotives looked awsomely rugged ?
The GE loco supposedly uses souuuuuper advanced sodium-ion batteries, and are stored beneath the walkways. I think there are 64 of them.
(Scource buried under a pile of something)
These locos are limited to pretty much 210 tons total over 6 axles, unless there are massive upgrades to infrastructure, which means the 285000 rule standard will be replaced with 315000, and then they'll start pushing for something crazy like 345000. (pounds gross load for 4 axle freight)

I was reading this thread last night and did a bit of digging.
Although not strictly hybrid the london Underground battery-electric loco no L35 of 1938 comes to mind.
This is I think the oldest example still in existance (non working) newer similar ones are still in use.
When the third rail power is off batteries supply power, and when on I presume charge them. These are used for works trains.

Is the RENFE Hydraulic Shunter 305 and it's smaller counterpart a hybrid?
No, at a wild guess diesel/hydraulic means a diesel engine powers a hydraulic convertor which in turn powers the gearbox making it move.
diesel/electric-engine drives a generator which when turning makes electrity which is then used by the electric motors to make it move.
Hybrid is having 2 different types of power_ diesel/battery for instance to power the traction motors.
The batteries will be charged when the traction motors are not taking all the electricity the generator produces while the diesel engine is running.
If I've made a complete hash of that someone feel free to jump in, it's the best I could do without getting a headache.
Sam Smiths pure brew coming up.
