Trains used to run on few types of fuel, steam powered (coal), gas/petroleum, diesel, diesel electric. Steam engines (coal) were broadly used throughout the world, many great locomotives were built in the Steam era, revolutionizing the whole industry. Sep 09, · Trains use deisel-electric locomotives to get down the tracks. A diesel engine turns a generator which powers electric motors at each drive usadatingescort.com is used by train.
On the newer locomtives the lead unit can see how much fuel is on every locomotive that is MUed to it. When a train comes into a major yard like CHI, or KCK, then if the train how to sign word document with digital signature continuing on and needs a new crew the yard controller will usually ask how much fuel they have. If it is to low, the fueling truck will be called to refuel all motors.
I imagine that locomotive fuel capacities today are probably 5, gallons. A lot depends on the RPM's of the engine at idle and max. Number of cylinders will also greatly impact fuel usage. The SD45 was a fuel hog because of it's 20 cylinder engine,the SD was better with 16 cylinders. I can't remember the figures,nor find them online. Maybe someone can help with this? As for the comparison between trains and trucks. Look at the different sizes of engines between the two,the amount of tonnage pulled,then factor in grades,speed,weather,operator habits,etc.
I think trains win out in all aspects. What newer locomotives have this capability to see how much fuel is on every engine in consist? When the tower or dispatcher wants to know how much fuel we have we check it the old fashioned way and visually check gauges on each unit.
Way back inwe did some NJ to Chicago fuel consumption tests to generate the relationship between ton miles per gallon and train HP per ton. As I recall, we calculated about 15 loaded trailer miles per gallon and about 25 for empty trailers. I'll have to see if I have a copy of that report around somewhere. Usually the foriegn power is at full throttle while the home units are enjoying the assist at idle.
According to the AAR, today's locomotives will move one ton, miles, with one gallon of fuel. Modern locomotives have a fuel capacity between 4, and 5, gallons. That's usually good for about 1, miles.
We have a computer program that tracks the fuel usage. The computer estimates the miles run and calculates the fuel usage. It's remarkably accurate. But we do get a visual reading to confirm the fuel level. For TV11 with three locomotives, the fuel economy was 11 loaded trailer miles per gallon, 18 for empties.
For TV12M is was 2. Wasn't that what they sold railroads on in the 70's on the 40 series compared to the F's? On the fuel side, it's not strictly units x fuel burn rate, but the specific fuel consumption.
That is, how many HP-HRs do I get out of the beast when it burns a gallon or more properly, a pound of fuel? On a small RR, you might have to look at the actual trains operated to see if you can practially reduce the number of locomotives and what the what is male menopause midlife crisis against the schedule would be if you did.
Didn't directly answer Ramrod's question, but: Oltmannd's figure of 11 to 18 loaded trailer miles per gallon is the one you want to go with; well documented and researched.
Which you can compare to a modern over the road truck at, at most 3 to 4 trailer miles per gallon. So there really isn't any comparison -- a train is anywhere from 4 to 6 times as fuel efficient as a truck. Which it never is! A longer train of double stacks will be slightly more efficient, for instance, than a shorter one, or one which is a mix of doubles and singles aerodynamic drag. A slower train will be somewhat more efficient than a faster one though not as much as you might think, and the difference is much less than it is for a truck -- again, aerodynamic drag.
Newer diesels how to train a sex slave truck or rail are more efficient than older ones, simply because they have much better controls for the prime movers. Depends where you're hauling the trailers. Put trailers on flatcars in Denver and haul them to Omaha on a slowish schedule, and maybe you'll use a sixth the fuel how to cultivate magic mushrooms at home would with trucks-- or maybe not.
But don't plan on doing that well on a TOFC round trip, there or anywhere else. No, TOFC's aren't as good as containers. Nor are 79 mph trains as good as drags. But then, a hot shot trucker driving 90 isn't doing all that well either, nor is one hauling post holes And if my experience is any guide, most trucks sit around the truck stops with their engines idling, not off, in spite of the signs -- so that argument on efficiency won't wash, either.
It's real hard to beat the fundamental physics as usual : a steel wheel on a steel rail has far less rolling resistance than a rubber tire. All else being equal, a train will be more fuel efficient than a truck. What we are looking at here in these various posts are the unequals.

There is on-going discussion locally about whether or not diesel locomotives are more or less fuel efficient than trucks for long haul freight. Lots of opinions but few facts. What are some figures that come to mind?

Posted by snagletooth on Thursday, June 14, AM. Isn't it true, thuoght, that even that new loco eat more fuel per say, as say, an SD70, compared to an SD that they use less using two SD70's compared to 3 SD's to hual the same tonnage?

As well as making old engines more efficient and greener, engineers are also experimenting with new forms of power, like biofuels and hydrogen fuel cells which create electricity by combining hydrogen stored in tanks on-board with oxygen to produce an electrical energy. Similarly, a typical train might haul 3, tons of freight miles and consume approximately 3, gallons of diesel fuel. The efficiency of this freight haul would be calculated as: ( tons x miles) / (3, gallons) = ton-miles per gallon. May 28, · Fuel usage is figured by Gallons Per Hour(GPH) at idle and full throttle.I imagine that locomotive fuel capacities today are probably 5, usadatingescort.com the 's locomotives such as the SD45,SD,U30C,and U33C were generally 4, gallon.A lot depends on the RPM's of the engine at idle and usadatingescort.com example,the SD had an idle RPM of and max of with it's E3 .

Trains use deisel-electric locomotives to get down the tracks. A diesel engine turns a generator which powers electric motors at each drive wheel. This system means there is no mechanical connection between the engine and wheels preventing stalling and no driveshafts or gears to break. It is not the most efficient way to move something but any inefficiencies are offset by increased reliability. Since their new locomotives are diesel-hydraulic powered.
The diesel engine powers a hydraulic pump which drives hydraulic motors. India and some other countries still have loads of coal powered steam engined for trains.
Europe has a lot of electrically powered trains with a good deal of the rest being diesel-electric. I'm pretty certain though that there are a small number of diesel only trains in use. The USA is mainly Diesel Electric with electric trains in metrapolitan areas and I think theres the odd few diesel only trains as well but they are rare. There are a very few petrol powered trains in Russia and China but they are not in commercial use as far as I know. There have also been some experimental kinetic trains as well.
These have a series of rotating fly wheels which get spun up to speed at each stop and the energy from them spinning is used to get them from one stop to the next. Compressed air has also been trialed for a similar system. I dont think either the compressed air trains or spinning disk trains will ever get to be used commercially but I could be wrong. Diesel is used by train. In extremely common words This diesel engine runs a shaft it really is hooked to a tubine-like rotor that generates electricity for the electric powered autos that turn the locomotives wheels in go back.
Locomotives can bypass extra or less 10 metric lots of freight in line with one horse-potential verses an wheeler which takes 10 horse-potential to bypass one metric ton of freight. Trains for long distance mostly use Diesel. Previousely coal was also used , now it is not used as it creates a lot of pollution. Trending News. Homebuyers are 'depressed for good reason': Corcoran.
