My LEGO Ideas Entry: Austrian Class 310 Steam Locomotive

[steamengine]

Hi everyone!
I’d like to share my latest build — a faithful 1:35 scale model of the Austrian Class 310 Steam Locomotive, shown here in its elegant light blue livery used by the Austrian Federal Railways in the early 1900s.

This model features plenty of realistic details, including:

• the distinctive aerodynamic boiler shape,

• opening driver’s doors,

• a detailed cab interior,

• front lights and steps,

• leaf springs and standard magnetic couplings,

• and the largest original LEGO train wheels.

The chassis is fully articulated, allowing the locomotive to run smoothly on standard LEGO tracks.
Inside the tender, it’s also possible to install a Powered Up motor and hub — a gear transmission is already integrated into the rear bogie.

I’ve built and tested the model with real bricks to ensure both functionality and robustness.

You can see more photos and support the project on LEGO Ideas here:

Hope you enjoy it — and I’d love to hear your thoughts, suggestions, or ideas for improvement!
Thanks for stopping by, and keep the steam going!

I'm not a steam expert so I cannot say anything about the design but that it indeed looks streamlined to me. Like the colour scheme. It is not judgable from the photos, but for an ideas submission I would be interested to see the interior of the cab and or coal loading. But i'm kinda a sucker of seeing some stuff there and maybe be able to actually load coal (even when you have a hub in the tender).

Thanks a lot @LL1982 for your comment! 😊
I’ve created a render of the cab to show its interior — I tried to reproduce it as realistically as possible by carefully studying videos of the real locomotive.

Glad you like the streamlined look and colour scheme! 💙

If you’re interested, you can follow all the updates on LEGO Ideas — I’ll be posting more details and photos of the model there soon.

Hey @steamengine welcome to Eurobricks and Train Tech. This is the perfect place to discuss improving the model I would say. However don't use Eurobricks just as an Ideas bill board that is not why we are here :) (I see you also use reddit for that purpose, I understand that it is a way to gather support, but then put effort in the communities as well!!!)

Did you base it on:

Hey @JopieK, thanks for your message! 😊
I actually discovered that model through this video, but my build is mainly based on the original locomotive’s construction plans.
If you’re curious about any specific parts of the design or how I built certain sections, I’d be happy to answer! 🤗

Nice.

The slope, is it built by using flextube/soft axle as one of the parts?

Hey @Shiva Thanks a lot for the kind words, I’m really glad you like the project 😊

As for the slight tilt of the boiler, I didn’t use any flexible parts (although that would have been a great idea!). Instead, I worked with some Technic elements, which allowed me to achieve that gentle angle while keeping the structure solid enough.

On top of that, I built several arches to create the smooth, aerodynamic shape.

Since I also built a physical version of the model (not just the Studio file), I tried to use parts that are easy to find and still in current production, to make the project more “buildable” in real life.

Hi,

Looks great! :-)

Pysical model is a Big + in my book.

Technic elements? Then I think of liftarm + brick, of those.

Hi,

Thanks for that shot of the interior. I always like it when you have some dails, levers and such. But should the firebox not be lower? Forgive my lack of knowledge on steamers, but the only one I saw had it at deck level. 

On your ideas you have these images of running and the tendor with axles, also great to share here imo. I'm especially curious how you did the motor and have the other axles with it. You have 4 on the tendor and how to make it curve. Im gonna try a six axle electric locomotive so testing stuff now, but always curious to see how others solve it.

Il modello fisico è un grande vantaggio per me.

Elementi tecnici? Allora penso a liftarm + brick, tra quelli.

It’s true! In fact, I love building and collecting the models I create in Lego Stud.io!
By Technic pieces, I mean a single liftarm in the center that creates that slope

CIAO,

Grazie per quella foto degli interni. Mi piace sempre quando ci sono manopole, leve e cose del genere. Ma il focolare non dovrebbe essere più basso? Perdonate la mia scarsa conoscenza dei piroscafi, ma l'unico che ho visto lo aveva a livello del ponte. 

Tra le tue idee ci sono queste immagini di corsa e del tendone con gli assi, anche queste ottime da condividere qui secondo me. Sono particolarmente curioso di sapere come hai realizzato il motore e come hai collegato gli altri assi. Ne hai 4 sul tendone e come farli curvare. Proverò una locomotiva elettrica a sei assi, quindi sto testando qualcosa ora, ma sono sempre curioso di vedere come gli altri risolvono il problema.

Great observation, and thanks for your curiosity! The locomotive’s firebox should indeed be a bit lower; however, as you can see in the photo, the black element prevents me from doing so, since it’s a structural piece running through the entire cab.

Still, I tried to keep it as realistic as possible with the colors and by referencing photos of the real locomotive’s cab I found online.

Regarding the tender and the motorization, I’m attaching an image I’ve already posted on the official LEGO Ideas website, where I show that specific detail about the motor setup and the bogies.

I should also mention that I used the 88011 electric motor, since it’s currently the most readily available official LEGO motor.
