Second day of a three-day layover in Chicago. No Newswire story or Kalmbach video posted yet, so if you go – the ‘official’ recommendation is to park at the West Chicago Metra station (free parking) and ride the shuttle buses provided to the actual site … about 10 minutes, they say. I’ll be there part of the day today.
Set your GPS to 475 Main St, West Chicago IL. That’s not the station, but it’s the civic offices directly across Main St. from one of the parking-lot entrances.
Have fun Mod-man! I’m sure you will!
PS: I hope you can get close enough to have a good, technical conversation with the steam team members. I’m sure they’ll enjoy talking with you.
A “give-and-take” with you will be a lot more enjoyable for them than the usual “How do you steer it?” questions!
Have fun. It’s a great display. I saw it pass my place Friday and I’m going to watch it depart Tuesday.
My adult son and I went to West Chicago on Saturday and we had a pretty good time of it. The crowd was well managed and well behaved and it wasn’t too hard to get some good shots.
Probably there the same time with you. Made a overnight stop in Naperville on our way back from Oshkosh Friday night.
T-Shirt lines were crazy … will see about ordering online.
A few notes:
West Chicago presence was awesome. Go on their Facebook page (if you do that) and comment that it was. No problem with parking, no problem with shuttles, no problem with access, free iced bottled water for everybody (and no running out!), properly managed lines for the attractions, etc.
Thousands and thousands of people, most of whom were not ‘card-carrying railfan’ types. Constant crowd walking both ways across the bridge, independent of the shuttle buses. The event ran until 4:00 but new people weren’t admitted starting a few minutes after 3. Lines for attractions were hopelessly long, and isn’t that a wonderful thing, considering.
Crew was there and stayed accessible. Austin Barker gave me a rundown on the Dickens-Barker burner, the problem with the right-front packing, and the current state of Green Velvet oil availability; the engine is burning waste motor oil, apparently well enough ‘prepared’ that there is no firing difficulty with it. Ed Dickens for some reason appeared to be avoiding me, but he was the soul of civility to a VERY wide range of people, some of whom were … difficult. (He has a Weimaraner, he likes tugboats, he signs hats in green because that’s the color pen he uses for inspections…)
It turns out the boiler pressure has to be kept above around 200psi, so they periodically blow back up all the way to 300psi (not some lower layover pressure). How they were doing this earlier in the day was fascinating if you knew what you were looking at… there is what I can only describe as a piece of 2x4 covered with tinfoil that is stuck in the primary-air inlet, and when that is removed natural circulation through the stack is enough to allow the burner to be fired on high turndown, with no visible haze (you can see the heat ripples). I did not observe the rate of pressure rise, but it would logically be relatively slow. A
Great report Mod-man! Thanks!
One question though, just what was the problem with the front packing? I suppose it’s corrected by now?
We parked at the middle school. We we got to the shuttle stop there was a older couple whe said they were waiting there for amost a hour. I ordered a Uber and had them join us ($5 well spent).
Noticed a pair of hoses running between the split sections of the train (one leaking water) was that for cooling the cars that they had open to the public?
Very similar to what I’d expected. The piston rod was CNC-machined and had a small runout mark not fully polished out. This picked up the edge of the metallic packing and unseated it slightly, which allowed the steam blow, and not incidentally began building up a phenolic-like layer of cooked oil that precluded reseating the packing easily.
So something reasonably easily diagnosed, but taking a longer time to actually fix, which was consistent with what we observed in the early days of operation.
They now have about 3000 miles on the engine, and in some respects it still is considered ‘breaking in’.
In other news: we decided to take 55 instead of 57 back down, and chase the Springfield 110mph trains instead of one of the Illinis. We’d have been right on top of the wreck when it happened.
Thanks again Mod-man!
3,000 miles and still “breaking-in?” Not really surprised. And I’d imagine they’re “breaking-in” the head-end crews as well. Running a Big Boy is an art that has to be re-learned by the UP crews, and in this case they have to learn by doing.
My understanding is that there is ONE head-end crew at this point, Dickens and Barker. When hours of service say they can’t go, the Big Boy won’t go. (Although there was one fellow wearing a vest with ‘engineer’ embroidered on it who went up and down into the cab a couple of times – I should know who he is, but I don’t.)
Dickens confirmed this to a couple of questioners during the time I was listening; I don’t think it is exaggeration.
Now, I have little doubt that the logistics of stopping the ‘exhibition’ at these UP facilities across the system is to inspire employees to volunteer for assisting with the trips. It’s just that that help won’t extend to running or firing the engine when it is pulling …
It’s certainly true that the two of them are ‘learning by doing’ – and I think they are learning some very interesting things with the oil firing that UP manifestly couldn’t ‘get done’ with the 4005.
Overmod, 'Hegewisch,and rdamon, thanks for being our eyes and ears!
Especially you, Overmod! Think you could do a dissertation for us about what you learned, if you haven’t pretty much covered it all already?
I am still learning like crazy, and I suspect I still would be even if I had multiple beers with Mr. Dickens and Mr. Barker every chance I had.
The one thing that might be of interest at this point is some of the detail design of the oil conversion. The setup is basically a Thomas burner said to be very similar to the arrangement on 3985, but the flash wall is very thick (Austin gestured with his arms, hands about a yard apart) and the burner rear-firing in front of this, so not all the firebox volume under the arch is occupied by radiant plume. There is no refractory on the circulators (!) and any portion of the arch that was sitting on them has been removed (!!) so there is no real surprise that it steams like crazy with decent waterleg flow and to a great extent steam separation above the radiant section. It does not appear there is a serious quench problem with the waste motor oil plume on these exposed circulators, even though their temperature is tied closely to that of saturated water at not much more than about 300psi. I haven’t watched all the (excellently provided!) Trains videos of running coverage, so I don’t know if there is increased or decreased need to sand things like circulators, tubesheet or flues/tubes due to enhanced soot formation or distribution. I suspect it would be obvious.
As noted, very little if any pressure-induced ‘purge’ was conducted before maintenance steam increase was started about 12:30 or so. The time in between the removal of the insulated ‘damper’ block on the right side and the audible indication of pressure on the burner was not very long; in fact it took me by such surprise (I was expecting at least a few minutes’ purge) that I didn’t actually measure or even observe the interval. I was unable to determi
Too bad you didn’t see it in operation. It’s a thing of beauty in motion.
Then again you would have seen many foamers in all their finery making whistle and Choo Choo noises.
I don’t suppose I could entice you into ‘videoing’ it when you see it go by tomorrow morning and then putting the clip up and linking to it here… ?
If it’s any good and if you can tell me where to post it.Then gladly. I’m planning to watch it start up in West Chicago.
Something you might consider is being on the bridge to watch as the diesel puts the train back together. There’s going to be a fair amount of switching and moving to and fro to get those two water cars back behind the tender and the obs back on the rear of the train… I was unable to find whether they’re planning on doing that tonight, or sometime in the wee hours closer to scheduled departure if there’s less traffic then.
When you have something good, the easiest thing to do is to set up a YouTube account (with a burner phone and ‘free’ e-mail if you’re worried about “credential leak”) and then just copy the camera video to your computer and upload it from there. The YouTube software will do the necessary compression and format conversion if that is needed. I advise that you make the clip public and not restrict access, but disable comments.
Then YouTube will assign an URL to that upload, and you can copy and paste that in a post using the button with the little chain picture (for “insert link” or use the adjacent one for “insert video” (which will load it ready to render in its own dedicated window).
I will have to set a reminder to be watching the Rochelle camera at 9:45-10:30AM local.
Overmod: You are right about the switching work needed. That would be good to watch. When we got into town around 6pm Friday they had a tanker truck loading oil in the tender. I did not see them filling the water tanks.
Too complicated for me.
