4-8-4 Class 6P Steam Locomotive
A steam locomotive that I designed for my wife, which we will build once I get back stateside.
About this creation
This came about for several reasons. I wanted to build a 4-8-4 steam engine, and I wanted to make a better one than the first one that I made for my wife. The original steam engine that I made for her was a modified Emerald Night that could house an M-Motor so it could still have playability. Needless to say, that did not work out as intended. I will post that failed design later.
So this locomotive will be designated as 120479 Briana, named after my wifey. I chose blue as the color because it is her favorite color. It started out as stripping down the Emerald Night to just the drive wheel base and adding an extra wheel. I kept some of the same design features of the Emerald Night, such as the lead truck and cabin design. I was going for a nice cross between American and European (specifically the LNER Gresley class of locomotives from Britain and the Norfolk and Western J Class), which I hope that I have achieved.


The side view of the Briana. It is much larger than the Emerald Night, not only due to its 4-8-4 configuration, but also because the boiler sits higher. Since it is intended for passenger service, it has an overall sleek profile.


A front view of the Briana.


Back view of the Briana's tender. It has a light and a ladder, which is primarily a standard feature on newer tenders.


The front end of the boiler. A major difference between this and the Emerald Night is the "bullet" shape of the front. This was influenced by American steam locomotives, such as the GS line of locomotives and the N&W J Class, although it is more heavily pronounced.


The leading truck is the exact same as the Emerald Night. If it is not broken, why fix it?


The rest of the boiler. The details, which include the hand rails, and overall design is American influenced.


The Briana's drive wheels. This was very easy to create since I already had the base from the Emerald Night. All I had to do was add an additional wheel section, two wheels, and make the main piston driver longer.


The trailing truck, which will be one of two Power Functions Train Motors that power this locomotive. I went with this style of motor instead of the gear-driving motor to make it more discreet. Plus eliminating the gears inside of the boiler will reduce the overall weight, making less work for the motors.


The rear section of the locomotive, which is slightly altered from the Emerald Night. I have not seen many American locomotives with the side sloping design in front of the cabin, and therefor wanted to keep it.


A view of the inside of the cabin. It is shorter inside that what I originally wanted, but due to design issues it ended up this way. At least it can still fit a minifig.


The Briana's tender. It is a very basic design, yet it is still effective.


The tender's wheel design was inspired by the 3 axle trucks design by Mike Kollross. This turned out to be a very useful design concept as it creates the illusion of a solid wheel base, yet it is allowed to articulate. This is also the location of the second motor.


The two top sections of the tender are able to be removed to allow access to the battery box and receiver.


The yellow section represents the battery box, and the red is the receiver. The spaces in the bottom and at the front are to allow the cables from the motors to fed to the interior of the tender.


The wifey, engineer/train driver of the Briana, stands next to her locomotive.



I hope you enjoyed viewing this, and please rate and comment! If you have any design change suggestions, please share them. I am always open and welcoming to constructive criticism.

Quoting Sir Seamus the 1st This is very similar to the emerald night. I like the colors(color) and mostly I like the design! Good job!
Yup, it is very similar. This is the first steam locomotive that I designed with LEGO, so I took the Emerald Night's base and built upon it. I threw in some American influence to make it a nice blend. For example, no European steam locomotives (at least to my knowledge) have the rounded "nose" at the front of the boiler, but American locomotives did. A lot. I believe a Russian locomotive did, but it did not hit mass production.

Quoting David the Fire Ninja Jedi Woah! This is awesome! I like the curved elements! I really like how you write the details for the creations you make! Excellent! I can't wait to see it when you get back to the states and build it with the real bricks! You can get more detailed pictures and demonstrate the movement!
Thank you, I am looking forward to building it in real bricks, as well! And I will definitely post new pictures and possibly a video of it then.

Quoting jd davis good luck with that 4-8-8-4 loco if you want ill post my southern pacific version of the union pacific big boy and this loco was designed superbly
That would be most appreciated since I do not have access to real Legos right now (being deployed kinda hinders that), so making the front drive wheel set swivel at the right spot is difficult. And thank you, I am pleased with how this locomotive turned out.

Quoting jd davis Exellant work there. you know, ive wanted to create my own emerald night 4-8-4 knockoff for quite a while but i didnt know how to do it
Thanks! This is not intended as a knockoff, it is supposed to be an American-European blend, and a testing ground for future steam locomotives (I am working on a 4-8-8-4 Mallet).
