  1. Wonderful work, Wolf. The balance between detailing and streamlining is so challenging, and you nailed it!

    Union Pacific FEF-3 #844: The Living Legend

    In progress! Several elements of the locomotive are being rebuilt after the first trial run period. I am also decreasing the gear ratio from 3:1 to 1:1. Pilot truck, trailing truck, centipede tender, gear tower...all improved. These extensive changes take time, but ensure that the final build will be a great runner and fun to build. Thank you for your continued interest!
  3. Hello all, I would like to share with you my most recent model. It is currently digital, but a physical build will be coming soon (with instructions). UP #844 is one of the most iconic locomotives that has ever graced the main line. Both powerful and elegant, she has captured the attention and imagination of railfans since her delivery to Union Pacific in December of 1944. #844 was the last steam locomotive delivered to UP and the only steam locomotive of any American Class 1 railroad that has never been retired. She has seen revenue and excursion service for over 78 years. During this time, she has had several modifications and upgrades. Some minor, such as a livery change and some major such as a Worthington SA feedwater heater added around 1955. For this build, I wanted to capture her essence and model her as she would have appeared in April of 1949. A careful eye will note several key features: by this time she was modified to be oil burning, a mars light had been installed, she was still using the Sellers exhaust steam injector and she wore the two-tone gray paint scheme in Harbor Mist Gray and Armour Yellow. This model is 8-wide, 1:48 scale and displays #844 as she would have been seen while pulling the Overland Limited, Los Angeles Limited or Portland Rose in April of 1949. #844 represents the absolute apex of duel-service steam and I want this model to represent nothing less. It is powered by two large power function motors with a 3:5 gear ratio so that she has both high tractive effort and can travel at high speed. Next step…building the instructions and ordering parts!

    Fascinating, this was not my assumption at all. Well then the 844s differential is getting scrapped and the gearing ratio will be reduced to 1:1. The 3:1 ratio I originally designed combined with XXL drivers allowed very high speed, but did not have enough torque at low speed to start much of a consist. A ratio of 1.3:1 might be it's magic number...to be determined in rebuild #2.

    Thanks Jeffery, very insightful, love your builds. And there have been no issues with two IR receivers? My biggest concern is one receives a signal and the other does not causing one to increase or decrease rpm while the other tries to stay the same. This is assuming the wiring is set to receive the same color coded command from the controller (all wiring on the blue connector for both receivers so only the Blue knob on the controller needs to be turned to give a command to both recievers at once)

    Glenn, with two L motors (facing each other, and connected to the same gear, I assume) wired to their own receiver, do you not run into issues with one motor spinning faster than the other? I could see this happening either because one receiver didn't acknowledge an order from the controller or because one motor has a slightly different rpm due to age, or other factors. The only way to avoid excessive wear and tear on the motors would be to install a differential within the boiler. I have gone down that path with the 844, but after looking at my mechanical disaster and/or masterpiece, I thought it was worth it to pose the question to you.

    Thank you both! Having this thing finished will be a bit of a dream come true. First draft of the walschaerts valve gear is running...a video is over on my flickr.

    Union Pacific FEF-3 #844: The Living Legend

    And I love the support! Its progressing! I have wheels, stickers and custom rods/valve gear pieces being drafted or on their way to me. Lots of work to be done with trial runs, but it is coming together. Thank you for your continued interest!

    Union Pacific FEF-3 #844: The Living Legend

    I'm not yet sure. One of my "building beliefs" is to have instructions be available to as many folks as possible while also helping offset the cost of the initial build. My other instructions are $25 each, so somewhere around there is reasonable to expect. I hope to run it at Bricks Cascade next year, so I have got to hurry and get this thing put together and started on its trial runs! https://www.brickscascade.com/

    It will be powered by two large PF motors within the boiler.

    Union Pacific FEF-3 #844: The Living Legend

    Much appreciated @Vilhelm22! I am quite happy with it so far, I am building her exactly as she would have been in April of 1949 at 1:48 scale. A full greyhound Overland Limited consist would be incredible! I hope to see that of yours someday.

    All parts are in and the build is underway!

    Union Pacific FEF-3 #844: The Living Legend

    Thanks! I've done all I can do keep the part count low, all the internal pieces will be colored purple indicating you can use any color you wish...but yes at this tier I think all models get a bit expensive if you aren't sourcing from your own supply. Worth it in my opinion!

    Union Pacific FEF-3 #844: The Living Legend

    On second thoughts Zephyr...I think I've delayed long enough. I'll order the parts this weekend, progress will be slow this time of year, but at least it will get started. Thanks for the motivation!

    Union Pacific FEF-3 #844: The Living Legend

    Thank you @Mattie305! Historically dating her to the spring of 1949 was difficult but I am confident that I pulled it off correctly. I am using a 20 tooth technic gear as the drive gear which connects to a 12 tooth technic gear as the driven gear. (Driven/drive = gear ratio -> 12/20 = 3:5 ratio). As far as weight and speed goes...I wish I knew! I will only have a good idea once I put her together. No updates as of yet, I was moments from making the big order when a couple (good) life events popped up. It's killing me but I will have to put off the part order for a little while longer. I am a geologist and caught in the summer rush of field projects. Fall and winter will come soon...then I am hoping to begin the build, testing, rebuild, retesting and finally...final instructions. If there is a silver lining its that this will give me time to fully flush out the decals with Monty's Trains so that each instruction set will also come with a digital file of all the decals. I have a copy of the plans for the locomotive including lettering and numbering...cant let that go to waste!
  17. Hello! I wanted to share with you all my most recent build,The New York Central K-5b Pacific Class 4-6-2 #4915 with Henry Dreyfuss' streamline design, otherwise known as The Mercury. The model is 8-wide and is designed to fit all standard lego track geometry.

    Union Pacific FEF-3 #844: The Living Legend

    Thank you @Vliebricker! Yes that is correct, the official name is "two-tone gray" and it was a paint scheme used by UP during the 1940's until 1952 when a directive ordered all locomotives back to black. While the scheme of gray and yellow was very short lived, it made an eternal impact on the rail community. So much so that they repainted 844 (then named 8444) in two-tone gray once again in the mid 80s, commonly referred to as the greyhound scheme.

    Very kind, thank you! Yes me too, draft instructions are in progress, physical build hopefully coming soon. Yes, I will be selling instructions...stay tuned!

    Union Pacific FEF-3 #844: The Living Legend

    Thank you! Yes will do, hopefully a post of the physical build soon. Much appreciated! I love your TTG challenger, I can't believe we both had these projects brewing away at the same time. Kind words, I was fortunate to find a boxpok 3D file. The physical model will hopefully have different counterweight sizes too.

    MOC UP #844 Power System Opinions

    Yeah I plan to reinforce the whole assembly, with some thin liftarms and probably will double up the brick tower if not convert the whole thing to technic liftarms and connectors. Thats great feedback that you have had issues with the bricks/plate method, I will almost certainly convert the whole thing to be a technic assembly.

    MOC UP #844 Power System Opinions

    Hello all, I am hoping to start a discussion on the types of geared power systems that folks in this forum use to power their steam locomotive MOC's, specifically larger builds with 3 or 4 driving wheels. I am partway through a build of a Union Pacific FEF-3: #844. I want to power this locomotive with two large power function motors (Item No: 99499c01) and I am struggling with choosing the appropriate gear assemblage to transfer the power to the drivers. The pictures below are the two methods I have been experimenting with. Assemblage #1 is the power system used on Brickmania's S160 Locomotive recreated here for demonstration only. Assemblage #2 is just a basic motor to driver setup. Rumor has it that the NYC Mohawk from Brickmania is powered by two sets of the S160 gear/motor assemblies, can anyone verify this? My goal is to make the #844 model true to her real life counterpart - very fast and very powerful. The renders were made quick and dirty, please excuse the clipping of parts, they are just to show the two systems. Any good ideas? Thank you all! Overall locomotive: Gear assemblage #1: Gear assemblage #2

    MOC UP #844 Power System Opinions

    I am hoping for speed and strength. My worry with one L motor is that I won't have enough torque to pull a significant consist. The gear ratio should actually be 3:5 to the driven axle (20 tooth gear down to a 12 tooth gear) which is then connected to XXL diameter drivers. I think that one L motor wont provide enough torque to get a significant consist rolling. Ultimately I would like this to have a fast running speed, akin to the real life counterpart.

    MOC UP #844 Power System Opinions

    @zephyr1934 I agree, axle connectors are a must in my opinion, otherwise all the strain is being put on the main rod which is brittle and more for show anyway (on Lego models). I used that bevel gear system through the frame on the Mercury with a motor assembly like option 2 above, but option 1 is probably much stronger. I have come up with a third option...both motors will turn in the same direction relative to their orientation here (i.e. one of them will have the polarity reversed on the controller). Gears are in blue so they are easier to see.
