3 EMD SD70ACEs up front restart 12,000 ton train on a 2% Grade, Moffat Tunnel Subdivision, Colorado

[@Boberrosini]

Why do Americans still use non-electrified tracks? In Europe almost everything runs on electric. Locos are newer, but in USA seems time stopped 50 years ago.

[@RailBuffs]

Page 2-5 second paragraph should explain it. www.freightworks.org/DocumentLibrary/CRGMSAIS%20-%20Analysis%20of%20Freight%20Rail%20Electrification%20in%20the%20SCAG%20Region.pdf

[@Boberrosini]

That is well explained answer. Now I understand why US railways stay where they are. I am curious though, whenever I look at those trains, they seem to be bigger than ours in Europe. They have shape of brick, even Amtrak passenger ones :D

[@RailBuffs]

@@Boberrosini I have actually researched railroad electrification and recently it has become a more popular idea within the railroads, I think we'll see electrification in the US sometime in the future. Here are some thoughts on electrification: 1. After about 20 years the cost savings of electrification vs the cost of diesel fuel is about equal but the railroads in the US are private and don't want to spend the billions upfront to electrify the mainlines. And our mainlines are thousands of miles long in some cases. It would probably take a big donation from the Government to Electrify the mainlines as part of a step away from fossil fuels. 2. Electric locomotives could be powerful enough to pull our big trains but then the issue become power supply. I think I read that with a 25kV supply, on a steep grade like 2%, you would need a substation every 2 miles, with 50kV every 4 miles. The mainline featured in the video has about 54 miles of 2% grade, that's 1 in 50 to you, so that would require many substations. 3. Our Locos are big, 10ft wide, 75ft long, about 15ft tall, pulling a heavy train is a combination of power and tractive effort which comes from how heavy your loco is. A powerful engine that doesn't weigh as much will just spin the wheels and go nowhere. The SD70ACE T4 is the most powerful single frame locomotive in the world by tractive effort, from what I have seen, because we can put large traction motors on it for power and it weighs 214 short tons, that's 35.6 short tons per axil, giving 889kN staring, 778kN continuous tractive effort. I don't know all European Locos, but one that I do know of is the Eurotunnel Class 9 with only 400kN starring, 310kN continuous tractive effort. The SD70ACE T4 is the newer version of the SD70ACE in the video. What is Europe's most powerful loco?

[@McSlobo]

@@RailBuffs I know nothing about trains and viewed this video by accident but to contribute to this discussion I started Googling. Europe is partially very mountaineous (therefore e.g. Swiss SBB locomotives might interest you) and these mountains exist also in populated areas which means emissions are a concern. The answer also depends on what you mean by Europe because it includes Russia, partially. Trans-Siberian railroad is by the way electrified although it's in Siberia. Eastern Europe uses Russian gauge, Western Europe uses standard gauge apart from Spain and Ireland which might have effect on locomotive dimensions. I would say you should see List_of_largest_locomotives from Wikipedia. I picked a few interesting ones. Russians have "Granite" 2ES10, electric, 17000+hp, "two units" running across Urals which means they visit Europe occasionally. From Western Europe you could take a look at SBB-CFF-FFS Re 620, electric 10,700 hp (8,000 kW) which is ancient but still in operation, and SBB-CFF-FFS Re 460. I guess there's also a couple of DB Class 103 in sproradical use too. Specific purpose trains include two-unit Iore which is used to haul ore in Sweden. My home country Finland is flat so we only have Siemens Vectrons. Hope I didn't mislead you. :)

[@krpajda]

@@bcstechnologylimited896 not just American dollar. Commies also were a large proponent of electrification and most of Eastern European railways have been electrified around the same time as well. One of the major reasons why European trains can run on overhead electric power instead of diesel is that the trains themselves are typically a lot shorter. This is for a coupleof reasons: Most of all you aren't going as far. Freight goes as far as possible by sea, which is much cheaper than rail, and the shape of European coastline means you are almost always within a couple hundred km of a nice deep port. The expection here is the eastern European plain (western part of Russia) but thy have their own unique rail solutions with wider gauge and power you can't scoff at. It's also a plain so no huge hills to scale until you get to Ural but others already mentioned that. Second factor is the infrastructure itself. You have double track lines basically everywhere which lets you support a lot more individual trains allowing each to be smaller to move the same freight. Last but not least electric is more efficient and therefore a lot cheaper in the long run. The loco also has fewer moving parts, reducing maintenance costs.

The sheer amount of torque needed for this is just unfathomable.

[@RailBuffs]

Hey folks, first off, this train is destine for where I work, PRT at Wash, Utah. We transload sand into trucks and oil into trucks and tank cars and yes that car is painted pink. Before I started work at Price River Terminal I worked as a conductor for 20 years out of Helper, Utah. When I started in Helper the fleet was almost nothing but EMD SD40T-2's, DC power, simple, tough, and almost impossible to kill. I was working in Helper when the first AC's showed up for us to use in helper service. The DC locomotive powers up when you throttle up (generator), the AC has to wind-up first, charge the field (alternator), makes for different styles of train handling. The AC locomotive is a very finicky item, so many electrical components and sensors to maximize fuel efficiency such as, wheel slip, temperature, air flow, and exhaust. Now keep in mind, I'm an old person and I've been off the main line for several years now, (PRT is a class 3 railroad) but from what I can recall, as with all combustible engines, is that after they sit idle for awhile there is a build up of carbon as the engine temperature drops and with these big diesel engines with their ebb and flow of hot and cold and quality of fuel grade some build more carbon than others. Also with the modern day AC you don't hear wheel slip, if you do there is something very wrong or there is more tonnage than the unit can handle. The wheel slip sensors for each axle will reduce power, to the effected axle, to prevent the wheel from slipping. You can see it on the screen inside the cab, if you have that particular screen pulled up. I had one of the first generation AC"s have an axle seize one night just before we started loading coal at Savage, on the CV spur, while I was watching the tractive effort screen. I've seen AC's spit flames, excessive fuel, and spit sparks, excessive carbon. With excessive exhaust there could be many reasons, failure of any number of electrical components, failure of any number of sensors, or poor quality of fuel. With this video it could see any one or all of the above be the reason for excessive exhaust, but my guess, with being on a grade, waiting for two trains, the tonnage, I will bet that there was wheel slip and with the fuel consumption rate still being maintained at the time power to the axle and/or axles was reduced and the excess fuel not being completely burned. They probably wheel slipped many times before speed was maintained. The two on the end are remote control from the lead unit, I spend almost my whole career helping trains up and down Soldier Summit even with remotes on the end, but for me....EMD all the way

[@Evan60020]

Thanks for the explanation on all the smoke those bad boys were pouring out. I've never seen a diesel smoke like that.

[@Tom-Lahaye]

This is well explained, it was my guess only that the changing nature of load due to wheelslip caused the excessive smoke, as a blown turbo would cause a more permanent emission of black smoke, but you made it clear. I never realised the difference between the loading of a generator or an alternator, I did only notice there was some difference in reaction time between different types of locomotives after throttling up (I had a couple of oportunities to drive a locomotive on a preserved railway under supervision, I'm not passed out as a driver/conductor) At some point there is some squealing that can be heard, that must be the wheels working on the limit of adhesion and the traction control must be making overtime. But this was a truly spectacular departure.

I remember having to open the panel door past the Dynamic Brake grids to reset the circuit breakers that tripped the traction motor. You could enter this corridor from either side of the catwalk, those U-boats were on their final days of service as the Dash 8's showed up on the property, they were retired. 2 Dash 8' would replace 4 SD-40's depending on the territory they were operating on. So from the late 80's into the 90's the race was on to develop AC diesel electrics, that the class 1 railroads would buy into. To eliminate DC current with brushes in traction motors, and "short time ratings" to keep from burning up those traction motors was the task the railroads put to the locomotive builders, along with increased horsepower. The DX proved to be reliable enough that New Zealand took up with GE, which EMD didn't attempt to present a locomotive to market for the Kiwi?

USA, EMD Locomotives since the FT's, in the late 1930's had a 16V 567 engines, or 567 cubic inches per cylinder X 16 cyl's. The EMD locomotives in this video are 16V 710's, or 710 ciu per cylinder, or basically the equivalent of 32 Chevy 350's (each locomotive) that will run at full throttle for literally days at a time and will, with proper maintenance do it for 30 years. The turbos you hear are a very special design by GM that has a "sprag clutch" that is at lower speeds and exhaust temps, actually gear driven, and only becomes an actual exhaust/heat gas driven turbo between throttle 6-8 positions. The max RPM is 900. between throttle 6 -8 the HP increases from 2,800 HP to 4,300 HP, in just the last 3 throttle positions. That shows you how much an EMD turbo adds to the overall HP. Not to mention the AC propulsion technologies involved. I always enjoy running these EMD's on this territory, they will pull their rated tonnage rain or shine, just make sure the sanders are working and there is lots of it. Man will they PUULL!

I will tell you, if you have a GE on the head end, and there is a rain cloud, dusting of snow or frost on the rail, within 30 miles and you got no sand, you better call for a help, cause your gonna stall out, hopefully on the big tens, before you get to the tunnel district.

You wouldn't think it, but we had a nasty grade in Medora, ND that we climbed out of with 17k loads of coal from Glendive, MT to Mandan, ND. No roads to watch, as it's badland area, but man, took a lot of horsepower. Usually had 2-3 up front and 2 in back pushing/pulling, and top speed of about 5 MPH all the way. Took 60-90 minutes to make it 3 miles. lol Knuckles broke here and there. I got lucky, and never had to replace one on that hill.

Wow! What an amazing vidio! It always makes me so happy to see disels, they're my favorite! This remindes me of a time when I was struggling to do something, and finally did it in the end! It happend when I was once scared to ride a roller coster! I was really nervous and scared, and I was staring up at the coster and my haert was pounding like crazy, and my palms were sweating, and I wasn't sure if I chould do it! But then, my friend lalya took my sweaty hand and held it tight and said I chould be brave, and she whould be right next to me! So, I got on the ride with her, and we sat next to one another, and I held tight to her arm, and tried to relax as sweat was dripping down my forhead. As the coster slowly started up the lift hill, I took three deep breaths, and told myself I chould do it, and sure enough, as the coster reached the top and flew down the track, I screamed all my fear out, and actually enjoyed myself! Hope you liked my comment! Rain.

@@Blackscorpion1963 given this is a simple calculation I didn't think it necessary to explain. Given the fact that you're trying to claim my calculation is fiction without understanding it yourself demonstrates your ignorance and honestly you're only making a fool of yourself using that tone with someone who actually understands the subject (I'm an engineer) For the benefit of others who, unlike you, want to learn : The weight of the train is 12,000 tons and the grade is 2%, this means that the force, which is vertically down, is partly pushing the train downwards and requires at minimum an equal force to prevent it rolling downhill. That force is equal to sin 1.15 * 12000 or 240 tons of force. Its generally accepted that to climb an incline you need significantly more power needed to merely hold the train in place, good practice is usually 1.75x, hence 420 tons of force.

Many times that required that we set the train brake and bunch the cars backwards, and after being squeezed we would pull like the devil to get the thing moving.

Figure the HORSEPOWER @3:40 were the train is moving well.: (1) FORCE : 12000 tons on a 2 percent grade is 240 tons force . ie 480,000 Lbs. 3 locomotives in front, 2 in rear. Force per locomotive thus is 96000Lbs. (2) VELOCITY: unit #4 is BNSF 6255, about 73 feet long. unit#35 BNSF 9786 is 74 feet long. Figure the Horsepower @3.45 in the video. Units #4 and #5 take 7.4 seconds to pass those 147 ft of the two locos. The Velocity thus is 147/7.4= 19.86 ft/sec . (3) POWER Total HP of the 5 units thus is P= (480000 Lbs ) * (19.86 ft/sec) = 9.53 million Ft Lb per second. 1 HP is 550 Ft Lbs per second. 9530000/550= 17300 HP. TOTAL for all 5 locos (assuming the grade still is at 2 percent) Thus per locomotive is thus 1/5 or 3465 HORSEPOWER.

They are emissions exempt and run on higher energy fuel blends that would not be allowed on the street as well which meant by Horsepower hours of useable mechanical power produced they burn less fuel than anything else by a wide margin. Sad fact of engine history is right up until the federal emissions complaints acts pretty much every engine manufactures #1 bragging point and standard of excellence was its HP hrs/gallon numbers and who had the best ratio. After they were forced to meet emissions standards that number was never spoken of again because telling your customer that in order to be arbitrarily cleaner by some tree hugger standard now meant you had to burn 15 - 30+% more fuel to do the same work. That's why your modern 8000# 350 HP diesel pickup only gets about double the fuel mileage of a older non emissions compliant 80,000 # 450 Hp semi tractor trailer rig in the exact same driving conditions. Thanks to big government and fuel taxation greed ,we now burn way more fuel than needed 'to save the world' from 'evil big oil' (who just happens to make ~ 1/4 the profit per gallon as the tax man does) !!!!
