Incredible build @Kyle84! I am an enormous fan of the books and of course the film. Do you have instructions or a Stud.io file for sale? I would be happy to purchase a copy.

Wonderful work, Wolf. The balance between detailing and streamlining is so challenging, and you nailed it! -
Union Pacific FEF-3 #844: The Living Legend
AbleChristopher replied to AbleChristopher's topic in LEGO Train Tech
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! -
[MOC] Nickel Plate Road S-2 2-8-4 763

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. -

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! -

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. -

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. -

AbleChristopher replied to AbleChristopher's topic in LEGO Train Tech
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! -

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!
