Thanks to this thread I realized oh poo poo, I work near Ogden so I am heading out to try to find a spot along the tracks out by Morgan. I wonder how busy it'll be. https://youtu.be/Xudh8KWvGRg It was pretty awesome. wilfredmerriweathr fucked around with this message at 22:55 on May 8, 2019 |

I got several good pacing shots today, including one in the brief snowfall between Evanston and Castle Rock. Video will be coming, but for now here's a snapshot of two horses racing two iron horses.

There was a ton of that going on with the Big Boy the first day heading back East out of Ogden. Dozens of people trespassing on the tracks. Saw whole families with little kids walking between the rails on the active mainline. I also filmed a woman nearly getting hit by the Big Boy because she was standing too close to the tracks filming on her cellphone. It was nearly a repeat of the woman hit by 844 last year.

JuffoWup posted:At the 50s mark. Is that a covered wagon on the hill? Didn't think you'd see one being used anymore. I'm pretty sure it was. I have no idea why it was there. Maybe someone planned way ahead to pose an interesting shot, but even when the big boy was in service it would have been an anachronism so I doubt it. Colostomy Bag posted:What a god dang magnificent machine. 1) If you're talking about the locomotives, the original plan was to have 844 and 4014 run separately to Ogden, then doublehead back to Cheyenne. In the end they were so late getting 4014 running that they skipped the separate trip for 844 and doubleheaded it in both directions. The diesel was there primarily to provide compliance with PTC, since it would be quite difficult to fit out a steam locomotive for it. That said, UP has run diesels in their steam consists since long before PTC was a requirement so that if the steamer had a problem they could still move the train. 2) I don't know, but I do know that the tender came off of 3985, as they didn't have time to convert the big boy's tender. They were almost identical anyway, and 3985's tender was converted to oil back in the 70's. Disgruntled Bovine fucked around with this message at 21:51 on May 24, 2019 |

Colostomy Bag posted:What a god dang magnificent machine. 1) The previous poster was correct about the change is plans for the consist, but the diesel wasn't there to provide PTC compliance. A consist is only PTC compliant if the leading locomotive is PTC compliant, which 4014 is not. Diesel locomotives in steam powered consists are usually there to provide insurance that this train can get the hell out of the way quickly in case the steam locomotive fails. In addition, they can be used to provide dynamic braking and propulsion if necessary. In the case of such equipped locomotives, like any excursion train with an Amtrak locomotive behind the steam, they can provide head end power for electricity on the passenger cars. 2) In short, the locomotive had a pump onboard that transports the oil from the tender to the firebox.

I have seen videos of the 3985 and 844 pulling freight without a diesel in tow. My understanding for this setup, the diesel is there for not only dynamic braking, but also just rides along with some braking applied. Passenger cars are fairly light compared to the freight cars the bigboy was built to haul. So to keep her under some control, some other way was needed to mimic the pull of 50+ freight cars.

Passenger cars are fairly light compared to the freight cars the bigboy was built to haul. So to keep her under some control, some other way was needed to mimic the pull of 50+ freight cars. I heard a lot of speculation from various railfans on the trip. Some said they were occasionally running the dynamics to make the steamers work harder, while others said the diesel was pulling to avoid putting too much strain on the newly restored 4014. One thing that was fairly obvious however was that the rear engine on 4014 wasn't running at full pressure. You never see any steam coming from the rear cylinders, whereas there was always steam coming from the front cylinders and the cylinders on 844. They had to be receiving some steam though as it is essential for lubrication. Unrelated fun fact: they overbored the cylinders on 4014 as part of the rebuild process to clean up wear. They were originally 23 3/4" and were overbored to 24". The markings on the cab were updated accordingly. Technically that makes 4014 around 2% more powerful than it was in service.

There was no steam coming from the rear cylinders because they applied the packing around the cylinders properly. The forward cylinders had a small leak since the packing was installed with just a few little gaps. It's not enough to impact their operations, but enough to let that visible steam escape. The forward and rear engines are not independently controlled; if steam is going to one, it's going to the other. The diesel locomotive was used to apply dynamic braking at some points to simulate a heavier load simply to help break in 4014. It's not that hard to control with a lighter than usual train.

Are the cylinders on 4014 arranged with a high and low cylinder on each drive rod, or is one set of wheels using high pressure steam and the other low pressure?

The big boys are simple articulateds, that means they only use the steam once. All four cylinders are fed high pressure steam. A "mallet" style compound articulated locomotive feeds high pressure steam to the rear cylinders, which then exhaust into larger low pressure front cylinders. The sizes of the cylinders are balanced so that both sets produce the same amount of power, despite the drop in steam pressure. Compound locomotives are more efficient, however the large low pressure cylinders result in a lot of reciprocating mass. As a result most compound articulated locomotives were slower than simple articulateds.

Yeah, it took the UP 5 years and 4 million dollars to restore 4014 to operating condition. Despite being the only US railroad with an active steam program and having restored a Challenger (3985), most railfans never thought UP would restore a Big Boy, simply due to the size of the undertaking.

ToxicFrog posted:Stupid question: the black car behind each locomotive, with seven axles and UNION PACIFIC on the side, is the tender, right? So what's the yellow car behind that? Just more oil/water? So originally the Big Boys were coal fired. They converted 4014 to run on oil for various reasons (logistics, line-side fires, etc) but the forward part of the 7 axle tender was a bunker that held coal with a mechanical stoker screw running along the bottom to carry coal from the tender to the firebox of the locomotive. The rear portion holds water, and the coal bunker was converted into an oil tank which holds used motor oil. As JuffoWup said the yellow tenders are water tanks to extend the range they can go before they need to pick up more water, however they were converted from bunker C fuel oil tenders which were originally built for the UP's gas turbine locomotives. Bunker C fuel oil is roughly the consistency of tar at normal temperatures, so the tenders originally had steam heating lines in them to melt the oil so that it could be pumped into the turbine.
