That all depends. Remember, these particular loco's are 50 years old and can only lift half the load of an NR class (615 tonnes compared to 1230 tonnes). The electric loco's also had only 1500V in the overhead to play with and that limitation was a problem, particularly on the coal trains working up the Como Bank.
I'm A mechanical fitter, Started at the railways and have rebuilt locos from the ground up and they do have transmissions. A transmission is defined as a "machine consists of a power source and a power transmission system, which provides controlled application of the power". Conventional gear/belt transmissions are not the only mechanism for speed/torque adaptation. Alternative mechanisms include torque converters and power transformation e.g,diesel-electric transmission, hydraulic drive system
It riminds me of the old 900 class loco which looked very much the same going uup through the Adelaide hills when I was a kid . They were so slow you could walk next to them.
Forgive my ignorance but I assume by "double the hill" you mean set back and try again.Not a good idea in an automatic section which permits following movements! Highly illegal as well without authorisation. If the train is not going to get up first time then its not going to get up no matter how many times you try. American rules and regulations do not apply worldwide. Failures on this bank are quite common and assistance from the rear is normally the solution.
I wonder if any of these private companies ever thought of importing a few surplus Class 37 EEs from the UK? They actually have a higher tractive effort than a 44 and most were rebuilt with new traction generators, plus they'd have no problem on NSW loading gauge.
Marc Conyard the 37's are great locos, but in order to run in Australia, their cooling groups (radiators) need to be much larger, to cope with our hotter climate
no parts for them here, getting parts would be expensive, no local experience on operating the 37s plus no experience in maintaining them = loads of money
That line looks like it could handle a big electric the size of the old Milwaukee Road Bi-polar engines. Awesome vid though, those Alcos are really working hard.
Mate, what a mission this is, what are gtrease pots, why dont they have a loco at Hawkesbury River to give a push? Do you Know a driver named Gary Turnbull I live down the road from him.
Not quite as old as that section of the northern line in that case. Many would not realise that the line used to finish at Hawkesbury / Long Island and passengers would transfer to a steamer to travel Broken Bay into Brisbane Waters and Gosford. The line to Newcastle would recommence there. The construction of the magnificent bridge and Woy Woy tunnel (longest railway tunnel in Australia when built) changed everything.
I'm sure we have some old Dash-8s running around here that you could borrow. While it's great that you're using old F7s and all, I think you should upgrade for heavy freight duty.
why is everyone suggesting electric locos, isnt the power plant energizing those over head lines spilling out even more pollution than 3 diesel-electric locos? How much more horse power are you getting from them anyway?
For sure the powerplant pollutes more, it also produce more power than those three diesels, but that not the point. The point of electric over diesel is that the whole supply chain is (a bit) more efficient in favor of electric. Forthermore the location of the powerplant can be more remote, reducing the direct effect of pollution. It also greatly reduces the direct noise polution. Modern electic locs (like the TRAXX) can produce a lot of power en.wikipedia.org/wiki/TRAXX Compared to a modern "big" diesel from GE it roughly twice as much en.wikipedia.org/wiki/List_of_GE_locomotives#Evolution_Series_.28introduced_2005.29 That said electrics in this example may not even apply, if the strech of rail with overhead wires is short compared to the total trip. In the US and Australia only densely populated regions or main coridors are likely to have overhead wiring. Trains running long distance may soon find themselves out of reach of the electric network. In West Europe (Mainland) a fast amount of track is electrified (like the main cargo corridors) and most (freight) trains are electric. So using electric or diesel is down to circumstance / availibility.
Until they stopped, only two of the three locos were pulling the load. Once the third loco was "on-lined", they got going with ease! I would not be surprised if this was "Staged" or the result of "Human Error"!
this intermodal goes outer electrified line which is useless if you use electrics, this is the case for australia in this video and before you say "why not make a bi mode locomotive?" remember this video is very old and bi mode isnt exist
??? Wtf ??? Try running that one by Locomotive Ops out of Delec or Eveleigh/ACDEP back when. Are you for real ??? Ever heard of a banking- engine mate?

@youthwith Yeah actually you are right, they use the 12-cyl version of the Alco 251B, wheras the WDM-2(the most common diesel loco in india) use the 16-cyl version. But still they are not junk, just as the indian version is not. Or else they wouldnt have lasted for 50 years+. :-)
I am not a railway expert. I just like trains of all kinds, however.... ...it seems to me, these trains 'struggling' on any hill climb, are grossly overloaded or, under powered. This wouldn't be allowed to happen on a road freight truck, why is it permitted on trains? Has someone got a logical answer to this?
Electrics were commonly used when the rail system was vertically integrated. When above and below rail operations were separated, the owner of the network would charge an operator to run a train. If the operator chose to run an electric, they were also charged with power usage, despite the fact that electric locos had capability to feed power back into the wire. It ended up cheaper to run diesels, and an environmentally friendly power became redundant, unfortunately.
I think the company that run the goods trains couldn't be arsed dealing with buing the juice or they were American and didnt do OHLE come hell or high water!
They need stronger locomotives-In Australia, they have been buying a lot of those strong North American AC locomotives from General Electric and EMD/Catapiller-looks like they need that here as well as maybe some DPU locomotives.
Why do railways about the world persist in putting too much behind what locomotives are rated to haul? It's an arse for the loco crew, and train control, and only means delay while a banker is sought if it stalls. Better somehow to have only the rated load and no more in the start!
He stopped because he knew the (electric) transmission was about to be fried alive, and needed a rest. Two choices: - - Try to keep goijg, and melt the transmission. - Stop, and let the transmission cool down. Pretty obvious choice?
Yes it bloody well would. But we have Oil Burning American Based thinking here. Bloody Crap isn't it. Well Electric Traction was used before so the substations should be up to this. What the hell will happen when the oil runs out?
Ever heard of Electro-Diesels if you don't want to switch locos?. A UK Freight company is buying some and they are already used here in the UK (on 3rd rail electrified routes but the new locos are for 25kv ac overhead) in Spain and South Africa for freight.
well we don't have them here so its a mute point...... plus the wired system is owned by the government commuter rail system so the private freight companies would have to pay big dollars to use it one would presume. The big freight companies such as Pacific National would have done cost/ benefit analysis for each type of loco haulage, believe me
+188basstrom the greater Sydney area (which is as far as NSW electric overhead goes) is 1500 volts DC and imposes limits on how much power you can get out of it for freight - a sensible choice for its original passenger purpose years earlier, not particularly suitable for heavy freight purposes now. The coal trains typically run with 12000 diesel horsepower , sadly it seems its not possible to draw that much from the overhead we have for electrics
That was the 46's 'secret' A 46 had the whole state/national electrical grid to draw on, so speed was rarely forfeited, as astonshing power was available at any time. Diesel-elecs only have their puny glorified air compressors with fuel valves (injectors) to depend on, and the difference is embarrassing. Speed falls markedly, and the amperage draw on the transmission becomes intolerable, as you can see here.
Really? You know the train was overloaded? If that train was over the load it would not have restarted as the required tractive effort to lift it is much higher than what is required to keep it moving. Most likely one loco had laid down, and problem corrected before attempted restart, probably stuck contactor or something similar.
Simple economics. Put too many locos on a train and a job which makes a slim profit then runs at a loss. Loco shortages often mean trains run with just enough motive power. The train obviously came to a stand due to a problem such as a trailing unit failing to load up, clearly rectified after the train stopped. Maximum loads up banks like these are set so the loco operates within its design limit i.e. about 18km/h and amperage just under redline. Something was wrong here.
46's were fine while you had momentum and speed. In slippery conditions, a couple of full on wheelspins would be enough to lose momentum and force you back to series and if you didn't stick up you were lucky. Remember 46 and 44 loads were similar, the 46 load was tabled at roughly double the speed.
This train halving and 4 loco's einsetzen.2 smaller trains with two locomotives on each train. would be better and faster vorran and would save a lot of diesel, right? Would not even think of such as a professional driver as an idea. Why a giant train with only three locomotives driving, as in this video. Have already seen some videos where such train are station wagons on the railway line on the road and at a mountain the locomotives or the limits crossed the borders and the train to stop coming. The power but absolutely no sense.
TONNAGE IS TONNAGE AND HORSEPOWER IS HORSEPOWER! IF YOU WERE GOING TO DIVIDE THE POWER AND LOAD, IT WOULD HAVE TO BE DIVIDED EQUALLY, POWER AND TONNAGE BOTH! THE TRAINS TOP SPEED IS A HORSEPOWER TO WEIGHT FORMULA WITH THE GRADE PERCENTAGE FIGURED IN! THEREFORE , MORE GRADE EQUALS LESS SPEED! ALSO ANOTHER FACTOR IS THE AMPERAGE SHORT TIME RATINGS OF THE TRACTION MOTORS! HIGH AMPERAGE PULL AND SLOW SPEEDS CAUSE HIGH TEMPERATURES IN THE TRACTION MOTOR WINDINGS! EXCEED THESE LIMITS AND YOU FRY THE TRACTION MOTORS!
I love how the V set is just "Get the hell out of my way" and flies past it.
I grew up in the age of steam so I am not usually a diesel fan but the sounds on this video are great. Thanks for sharing.

Still, the sound of multiple 12CSVTs working hard with twin turbos would be nice on Cowan Bank.
Cowan Bank 8.6 k's of 1:40 grade..... Used to test new locos.

Listen to those babies purr, eargasmic.
That line looks like it could handle a big electric the size of the old Milwaukee Road Bi-polar engines. Awesome vid though, those Alcos are really working hard.
Great Sound!!
It may be better for the equipment to double the hill instead of killing traction motors and engines...
Nice grade, nice S currving to add resistance and put less locos .... recipe for stall.

This was 19 years ago, they're alco worlds not f7s and we already have hundreds of dash 9s
So the 44's and JL stopped mid-climb, but was actually able to start it back up
A lot of lines in America and australia are like that for trains travelling high speeds so their Center of gravity doesn't cause the train to tip.
Why would any railroad be using such old engines to begin with ?
