My dad is writing this so here he is, Hi, I lived up in the up of Michigan and took the highway 35 that ran along side of the railway and watched these trains many times on there way back from their unloading in other iron ore sidings. Great real stuff. Thanks for the memory jog. Alan W.

This is VERY captivating. I was not even looking for railroad videos, happened upon this totally by accident and had to watcch the whole thing. That train / ship dock gravity loading system is amazing, and that it was built well over 100 years ago and still working like it is today. Absolutely amazing engineering. you r documentary on this process is outstanding. The Smithsonian channel should broadcast this.

Just wanted to say thanks for the great video and specifically the historical information. As a Michigander and someone who has spent almost every summer in the UP, this is very detailed. I’ve done almost all of the local historical tours from Ishpeming to Sault Ste. Marie as well as the museums (especially railroad) and and have never gotten as detailed of information as is in your videos. Also thanks for the book recommendations, I’ll definitely be picking those up.

Thank you very much for this video. It gave me the opportunity to see what my father saw during his years working for the LS&I. Living almost all of my life in Ishpeming, I am eminently familiar with the passing railroad trains. However, I had even a closer association. My father began working for the railroad shortly before World War II and returned after the war, continuing to work there until his retirement in the 1980s. He spoke often of the Dead River Bridge, so I especially enjoyed seeing it. Best memory: Riding the rails allowed dad to pick out and cut down the best Christmas tree which he would drop off the train and we would go and pick up to use in our home. Thanks again.

Tuppoo94 The UP is very unique in that so much of it (towns and all) was created by the railroad and mining companies (who worked hand in hand) to facilitate mining, timber, or even recreation. Almost nobody lived in the UP apart from very small shipping towns before they came in. One of the most popular Michigan tourist towns, Mackinac Island, was also started by the railroad (prior to that it was just an outpost). Although this happened in the western US as well, there weren’t so many towns in such a small area created by private industry as there is in northern Michigan.

@ThornappleRiverRailSeries 5 жыл бұрын
As noted by the two previous replies, there's a combination of fitting the dock and "it ain't broke". So first and perhaps foremost, Cliffs isn't going to spend money they don't have to. And second, this ore car fleet is unique not just because they're short cars, but they're narrow, too. They had looked at buying new 24' cars when the BNSF and CN did for their Minnesota iron ore operations, but opted out in part due to the additional cost of re-engineering the cars to fit the narrow Marquette Dock. The 9000-series cars are ex-DM&IR and had to be narrowed by 8" to fit the LS&I's dock. In some of the scenes, you can see the difference in width, as the 1000-series cars for instance are even narrower. Combine all that, and so far they have not been able to justify the cost of new cars.

@ThornappleRiverRailSeries
@ThornappleRiverRailSeries 5 жыл бұрын
@jwernhol is correct, copper and nickel ore from the Eagle Mine. They are covered for two reasons: first, they are *just* radioactive enough to be considered a low-level hazmat in the US, hence the placards. Second, the ore is of a sulfide variety, so if it gets wet, it will create sulfuric acid, and there is a risk that it will self-ignite. Add to that the fact that the ore is a powder after the mill is done with the flotation process, and you'd end up with a muddy soup if it got wet. So ultimately there are good reasons they those gons are covered and sealed tight! The LS&I would have the same "soup" problem if the ore got wet, except the iron ore folks pelletize the ore so it will work in a blast furnace. Ore to be smelted is just fine as a powder, but in a blast furnace, the extreme upward draft would simply blow the iron ore dust away, when it needs to melt and fall to the bottom. So it is pelletized. Otherwise, after separation by floatation, the iron ore is in the same powder stage as the nickel and copper from the Eagle Mine.

You have to really admire a railroad that schedules trains around their crews’ down times. If you operate like clockwork it’s easier to have all the pieces scheduled farther out and everyone’s a little happier. When I was growing up it was a rare sight to see my locomotive engineer uncle at family gatherings because he’d been called just a couple hours prior to the event. Railroading is good money but you give up most of your freedom to get it.

What's "extended range" dynamic braking?
@ThornappleRiverRailSeries
@ThornappleRiverRailSeries 4 жыл бұрын
Earlier iterations of dynamic braking had stricter limits on how long they could be run at higher amperage. Since dynamics essentially burn off electricity through grids of resistor wire just like a toaster does, keeping the whole thing cool is a challenge. Later models extended the range with better cooling and such.

@ThornappleRiverRailSeries 5 жыл бұрын
The old U30Cs and C30-7s have dynamic brakes. They just don't have *extended range* dynamic brakes. Basically the older dynamics get too hot after awhile and need to be shut off, and the LS&I's big hill is long enough for that to become an issue. Newer units have much more cooling built into the dynamic brake system and thus can run much longer, effectively indefinitely I believe. For those unaware, dynamic brakes dissipate the electricity generated as heat using the same technology as your toaster uses to toast bread. So you can imagine if you're not doing anything to cool it down and you're running hundreds of times the current through it, that you may need to shut it down after awhile!
@railroadmike6843

@@ThornappleRiverRailSeries The extended range dynamic brake has more to do with it's effective abilities at lower speeds. The U and C 30 units were originally used in long distance main line service. They have standard dynamic brakes. The AC 4400 has a totally different system. It uses high power electric cooling fans in an enclosed compartment instead of the mechanical prime mover driven radiator fans on the older units. So at slower speed( the entire LS&I) there isn't enough draw for the dynamics to hold a train below 15 mph, where the AC4400 can draw dynamic brake down to zero mph.
