WEIRDEST New Locomotive?

[@SD40Fan_Jason]

Santa Fe was doing this 50 years ago, taking old covered wagon engines and rebuilding them with freight bodies. Check out the book "CF-7 From Cleburne to Everywhere. " by Cary Poole.Those engines got a new lease on life with ATSF. And then they were peddled off on shortlines all over the world. Even Amtrak owned several CF-7s. Many are still being used today, despite their non compliance with Tier 4 emissions requirements

[@atsf47legit]

ATSF is my favorite railroad, I've heard of them before.

The CF7’s looked ugly to some, but they were real miracle workers. I’ve heard crews praise the CF7’s for their flexibility and large windows

[@SD40Fan_Jason]

@@Coloribus2004 maybe it was the short little nose? The first railroad I worked for had about a dozen CF-7s and a pair of GP-7s. Except for the position of the batteries and the nose shapes, they were almost identical to each other to us crew folk.

Those CF7s were built before the Environmental Police Agency really started mandating all these Tier rules. I think they overstepped their power and have caused many things to cost more because of their actions. Besides many older locomotives were grandfathered and allowed to keep running. Just look at the Alcos and MLWs that are still running. Anyway I thought that the EMD that opened the video was a rebuilt with EMD components. Thanks for the info.

They asked about you tube train channels. I provid we d yours, and several others including Distant Signal with Danny Harmon. Helped both of them with Grandmother's permission, to set up and subscriptions for all the channels. They were absolutely excited and loved it.

I live in Erie PA. Wabtech has been more cunning, devious and cut-throat against their employees than even GE was. These workers have built locomotives for decades. They are skilled. But the company wants to move production to Texas and pay wages that are half or less, to laborers who have very little experience. In a short decade or so, watch for some Wabtech locomotives to have issues with quality and build. These will be the ones built by cheap labor.

[@arbigdog73]

Notice the Red light over the Ditch Lights on the Canadian National Unit. They use the Red light for rear DPU usage. I wished every Railroad would adopt this standard.

[@SD40Fan_Jason]

It's just one more accessory to maintain. Locomotives used to have marker lamps or sometimes called section lamps. There was a mechanical rod that changed the lenses from red to white and to green. While their usage became unnecessary in the 70s, any Locomotive equipped with such accessory had to maintain it in order to pass inspection. Broken or malfunctioning section lights were a defect and the engine could not pass an inspection while the accessory was defective. This included the bulb behind the lens that were not used! And yet in certain cases, it was cheaper to keep a working light bulb in the socket than it was to remove and cover the fixture altogether, so it stayed. Appliances, fixtures and other accessories that are not required or have been made obsolete, are really more hassle than their worth. And making something a standard requirement would need some safety background to justify its necessity. Red lights vs ditch lights or even a glowing headlight is probably not going to win any favor since both have the same meaning. "Train or engine here, stop before you reach the coupler, thanks!" The argument about flashing or "wig-wag" ditch lights has been a fundamental debate since the mid-90s when ditch lights themselves became a requirement. But the wig-wags are not required by law. Certain railroads prefer them because they feel it offers an extra level of safety while other railroads remain firm in the stance that its just not necessary at all.

[@railscenes4959]

Canadian RRs have been trend setters for safety. So while the previous reply seemed to think this use of a red marker used in DPU mode at the rear end is just another item to repair and won’t last, I think it is a good idea. After 40 years working the ATSF mainline (now BNSF Transcon) a red marker on a crowded main I think it is much better than a headlight on dim.

[@SD40Fan_Jason]

[@stevebollinger3463]

EGR doesn’t really treat the exhaust. It treats the intake air. The idea of EGR is to reduce the oxygen content of the charge (intake) air so that it burns more slowly and produces less nitrogen oxide emissions. You could do this by piping in CO2 from a tank to blend with the intake air. But exhaust is a cheaper and easily available source of air with less oxygen in it. So you pipe some exhaust into the intake air. This reduces trace emissions. But it doesn’t do it by treating the exhaust. SCR does treat the exhaust. I hoped to hear what all the additional cooling was for. It’s possible it’s for cooled EGR. Surely a tier 4 prime mover uses cooled EGR. This works by cooling the exhaust gases before recirculating them. But I wasn’t aware cooled EGR uses so much cooling. In a truck it doesn’t seem to. But locomotives do work a lot harder.

When you quote the horsepower and torque figure, is it for the traction motor or the diesel engine? If diesel engine, what are the specs for the electric traction motors? Also is there a significant difference between traction motors used in an electric loco Vs the diesel electric loco? Thx.

[@SD40Fan_Jason]

I'm no locomotive mechanic or anything but I know the way they measure a locomotives horsepower in the field is by attaching a dynamic grid to the generator output and measuring the amperage at max throttle. 3500 amps at 600 volts is just a little over 2000 horsepower. And then you are dividing that amperage between 4 or 6 traction motors, one with an ammeter in the cab for the engineer to see.

[@mickvonbornemann3824]

Seen those Diesel-electric-electric hybrids in Spain? They’re basically Diesel-electric locos with a pantograph ontop so they can run off overhead electric power when desired & run off the Diesel generator when required, or even put power into the lines, say on long descents, etc. Means a lot more versatility at I assume not that much more cost.

[@beeble2003]

Quite a bit more cost, and you end up as lower power in either diesel or electric mode. Neither diesel nor electric locomotives have enough free space in them to accommodate the equipment of the other.

@@beeble2003 You do know that virtually all diesel locos use their diesel engines to generate electricity to run electric motors. ‘Diesel-electric-electrics’ are also known ‘electric Diesels’. BtW there’s no space issue that can’t be resolved by making the locos a couple of metres longer. Go do a search. It really is as simple as sticking a pantograph unit ontop with the added electric switching & wiring. Yes some are a compromise, but there are ones like the Spanish ones that run like both a full power Diesel-electric loco & a full power electric loco, just with a choice of either. Although some have huge banks of batteries as well, that’s really another type that I wasn’t referring to.

As far I’m aware, the reason why locomotives use water instead of antifreeze is the engines leak too much. Antifreeze contamination of the oil will ruin its lubrication qualities & turn it into a milkshake.

[@Greatdome99]

Water works fine. Antifreeze is expensive and toxic. In cold weather, diesels are kept running to prevent freeze-up. Water in oil will also destroy engines.

⁠while they could use the same pink antifreeze as RV drinking water systems, it is probably still too expensive and messy most of the time.

[@ClockworksOfGL]

@@PaulN-x2q - For some reason, I know more about antifreeze than I should. In your car, when you add fresh antifreeze, it reacts with bare metal and forms a protective film to prevent further corrosion. As the miles add up, the pump slowly wears down, constantly exposing “fresh metal” that then reacts with the same corrosion inhibitors. Eventually the system “uses up” those inhibitors and that’s when you need to change the coolant. When carmakers switched to long-life coolants a few years ago, they had to redesign the pumps to reduce cavitation and erosion, some even switched to non-metallic pumps in spite of the high cost of glass-reinforced nylon parts.

[@SD40Fan_Jason]

@ClockworksOfGL the main reason locomotives do not use antifreeze is because they are running more often than not. And if they are running, the coolant will not ever freeze in normal conditions. That being said, I remember seeing instructions on a locomotive in Alaska to leave it running idle in Run 3 (throttle position) when the outside temperature was below -25C. I've also been a (trainmaster) of a short line that had to get out of bed at 11pm and go fire up some engines that would freeze otherwise.

And at low speed those old high power units just wheel slipped under full power. For example the 3800hp SD60 and 3600hp sd45s being rebuilt into SD32ECOs or UP calls them SD59Ms making 3200hp. Most SD50s and SD45s have been derated to 3000hp today if still in service.

Now this is totally awesome how some of these locomotive's gets rebuilt or replaced totally awesome 😊

[@huntersmith7127]

There It Is!!! That's The Locomotive I've Been Looking For!!!!

[@domself9611]

Great video! I'm all the way over in England, Am I right in thinking that our Class 66 uses a similar engine? It sounds exactly the same ticking over!

[@svenmartin840]

Sometimes a rebuilt unit is cheaper than a new unit. And I hope you get to go to Germany and do some filming there. Especially two stops away from the Porsche Factory. Where they have a huge classification yard in Kornwesthiem. And an a intermodal yard

Please explain how more cooling capacity effects emissions .

[@freedomfan4272]

Or research it yourself

1:07 the K1L13 horn and Ekyrail bell remind me of the VIA Rail F40PH rebuilds

The back of it looks like a hammerhead shark lmao

[@user-vh1uc6in7b]

Wow that was Locomotives NS and CSX Trains That Was a Fresh Paint?

[@cainsaffiliates2661]

Why are you not talking about “dynamic breaks”??? Are those really radiators or dynamic resistors above the Engine Hood???

[@beeble2003]

In the view at 2:24, the small bulge above the "CSX" letters is the dynamic brakes; the big bulge at the back is the radiator. Same position of the dynamics as on a standard SD40-2.

[@theestallion818]

Powerful and efficient locomotives is highly needed for longer trips passing states

[@DebbieSuttle-m9v]

Totally awesome locomotives and the new csx locomotives are being rebuilt Totally agree and the new ns locomotives too ❤

[@amtrak713productions8]

If your interested rn in Rensselaer ny they are converting p42dc 184 to a NPCU

[@ericcallender1575]

Didn't Progress rail make these for NS years ago?

[@smarquardt10]

I still love and miss all the emd units!!!! Just wish they can bring them back. Even the sd 45!!!!

[@fiercestcalmivebeenin9937]

The 40-2 is a good motor. "I wanted to hear the 6cyl 4" .. They run SD60's on all the locals up here, I'm actually surprised, sometimes, the power in them.

How does increasing cooling improve emissions?
