LEGO Train 12 Volts

Wow gorgeous masterpiece!

Good luck kyphur I've been there too ...I wish you to go to a house bigger than this one!

I have my own instructions on MLCad, the parts are about 2000 ...don't know the cost because I already had some pieces (for new orders I've spent over $ 300) Thanks HoMa and congratulations for your work! Yeah, this is the reason why I love this giant! This model: locomotive + tender is 80 cm long Thanks for the compliments Tiger, I'll post a video to show how this Goliath run over the curves and switches!

Thanks Rail Co, your words are very encouraging, I still feel little respect to the real MOC expert Thnaks patje soon I'll post new pictures The Big Boy run on the standrad track ...this is one of the first construction specifications Thanks Lego Guy Bri!

As previously mentioned, my personal production of BR locomotives was paused but not the planning of steam locomotives! The Big Boy couldn’t miss in my collection so I built a replica of Jayhurst's model because I think is the best Lego conversion of this iconic steam engine. Since Easter I have been involved in the creation of this goliath to give my tribute to the American railroads. My model is a little bit different from Jayhurst’s master copy because this version has lights, the cab has rear doors and the arrangement of the tubes near the boiler is more similar to the real thing (from my point of view). Big Boy histoty & technical data The Union Pacific wanted a locomotive that could pull a 3.600 ton train unassisted over the 1.14% grade of the Wahsatch. The designers determined that to pull a 3.600 ton train, a tractive effort of 135.000 lbs would be needed. Assuming a factor of adhesion of 4,0 the weight on drivers would have to be 4,0 x 135.000 = 540.000 lbs. Given an axle loading of 67.500 lbs each, this would require 8 drivers or an x-8-8-x wheel arrangement. The designers agreed upon the 4-8-8-4 design. Next, the horsepower and cylinder sizes were computed based on 300 psi boiler pressure. Although they weren't planning to pull these freight trains at 80 MPH, the Department of Research and Mechanical Standards designed them for 80 MPH in order to have a sufficient factor of safety built into the design. What resulted is considered by many to be the most successful articulated steam locomotive ever built. My Big Boy respects original proportions and is inspired to the exemplar 4023 in Kenefick Park, Omaha Nebraska. The locomotive is powered by 4 PF medium motors hidden in the boiler. In the tenders are placed the battery pack for the motors and a 9 volts battery to power lights It has been a challenge assemble the front light but it wasn’t a waste of time: I am satisfied with the final result! Now enjoy the show During the weekend I hope to post more pictures and may be a video.

Great MOC, the color reminds me the old set 7760 Remarkable the compactness of the model that hides the battery pack and the IR receiver!

Welcome aboard! Do you have a favorite theme?

Fantastic building ...the color is truly awsome! The shop at the ground floor is gorgeous! The shelves builded with glass and wood are beautiful!

Great idea to use the brick 1 x 4 with groove for the base of your basket! The shop looks very cool with black and white tiles! Brick on Tiger!

Perfect shape, this SUV look like a Range Rover Sport!

So little but so perfect! Very inspiring ...I want my own copy of this beautiful garden! The glass dome of the greenhouse and the dark green color are wonderful!

Perfect scale model and perfect choice of colors!

Welcome aboard ...I hope to see your MOCs soon Welcome aboard ...I hope to see your MOCs soon

WOW this can't be real! The work with the lights is amazing! I like the red engines! The scale is huge ... I'm speechless!

I didn't know that this supercar had four steering wheels ...this model is very complex but I prefer the set 8865! Great review!

Wow what a ship! I like the color scheme and the crew on the first deck! Superb masterpiece!

Awesome choice of colors, I like the green and white contrast. The small tank near the computer is impressive ...I like it! I've only a question for you: what is it the gate fitting?

Unreal work as usual Tony! Your gorgeous layouts are simply the best!

So simple but so perfect! Great containers!

Wonderful MOC, I like the water effect! It's nice to see your swimming pool inside a real lego layout ...I can see a mail wagon on the back!

This scene is already so great ... I can't wait to see the finished work!

This is amazing! Brick on!

Nice Starfighter and complete review! I like the variation of flight attitude of this ship!

It's amazing to see this beauty in action!

Oooooh I love this MOC and I love sushi too! The building technique is perfect, I like the use of crates to make the columns! The plant in the main room is just perfect!
