A 4-6-6-4 type steam locomotive. First conceived by the Northern Pacific in the 1930s, they were among the steam locomotives that represented "super-power" where engine builders learned to create locomotives that combined both power and speed. The first batch of 12 of these engines were first delivered in 1936 to replace double-heading methods. The locomotives please Northern Pacific so much in fact that 9 more were ordered in 1937. They could be found all over the NP's divisions hauling fast freight trains and reefer trains. Their 69 inch drivers allowed them not only strong pulling power but also the ability to go 60 miles per hour.

 

I thought it could bring a real "challenge" to those who want to build it. It has OVER 2000 parts total. It has a side rod system that needed to be reversed engineered a few times to perfect it to where no 3rd party elements are required. 

 

Unlike most other articulated steam engines I have seen on YouTube and other places, mine has a FIXED rear engine unit and a front free swinging engine unit just like Union Pacific 4014 that was restored in 2019 if I am correct. 

 

Description:

Locomotive is powered by 4 LARGE motors, these sit inside the boiler and provide the means of going forwards and backwards. Both the IR receiver and battery box sit inside the tender. I would recommend some extension cables given the fact that the locomotive itself is very long. The IR receiver also plays a part in the tender for the locomotive is designed to look like an oil burner. The bogies on the tender are specially designed to not only to look realistic but also to take turns at the same time. And the same can be said on the lead truck in front of the first engine unit. The cab will actually let you house an engineer and fireman to simulated them driving the locomotive.

This locomotive is also on The Lego Ideas website, here is where to find it:

Please help me get 10,000 supporters please.

Definitely better than my first engine. You invited me to comment in the 4-4-2 thread, and while there are areas that could be improved here, I don't want to be an *** and just run through them. I think this is strong, and could be superb. You are starting at a very high level.

I like that you went with the fixed rear wheelset, even though it might hurt performance - it's what I would have done, too.

Thank you and I knew you meant no harm. My papa would say some are stronger than others. I am just getting started. I will have more to come real soon, maybe freight cars or something.

My advice is twofold:

1) Try working on something much smaller to practice scaling and detailing - an 0-6-0 or or 4-6-0 or something along those lines. Smaller engines are a great way to hone abilities without facing burnout (you have less ground to cover, so you don't feel so taxed trying to 'fill in' spaces like you would with a big articulated engine).

2) Familiarize yourself with https://www.brasstrains.com/ . Without fail, it's my first stop when designing projects. While you cannot directly save the photos on their website, I enlarge them and then hit print screen and paste the pictures into MS Paint. Usually, I lift most of the pics associated with a given model. I then use the side-on photos to establish locomotive proportions (how long and tall the engine should be relative to the wheels I am using), and just start working up; wheels first, then boiler, then cab/tender. It seems to work really well in lieu of actual blueprints.

Funny you should say that, because I did the exact same way you did with your GN 4-4-2 and caboose. I actually built a WMSR 734 "Mountain Thunder" 2-8-0 and did the same thing on building it. I am currently trying to build a Canadian Pacific G2 with my taking on their premier train called The Dominion. But I'll be sure to upload my freight cars before I upload my steam passenger train.

G2s are sexy - looking forward to seeing it. Remember that you can use 3649 gears for the XXL wheels.

Thanks. It's not coming yet because the tender still needs work before the passenger cars. And as for the wheels, I might modify it to where it will accept larger diameter drivers. But for now, they will be standard because it will also be going to Lego Ideas to. I'll post the engine and tender whenever completed.

Hello Craig,

this is a impressive machine. But I have big concerns about curves. I don't think, you can drive trough to a Lego R40 radius.

Do you have build this monster with real bricks and test it? I think, it's impossible to create a big steam engine only digital without real tests. The pictures at Lego Ideas show the problems.

Can you show here more pictures? Currently looks your posting only like a advertising for the Lego Ideas project. Sorry.

The machine looks good but not finish and i think, you should go the way to finish this beast!

Where do you think my flaws are on my Z-6 challenger?
