Station for LGB Model Railway (Scale G)

Build Your Own Alpine Model Railway Station

A G-Scale Tribute to Davos Wiesen

Bring a piece of Swiss mountain charm to your layout with this detailed G-scale (LGB, 1:22.5) model railway station. Inspired by the iconic Davos Wiesen station on the Rhätische Bahn route between Davos and Filisur, this model captures the essence of alpine architecture — rustic, functional, and beautiful. While not an exact replica, it stays true to the original’s style, with some creative liberties to simplify printing and assembly.

🖼 Image Note: One picture generated by ChatGPT from the original photo and model rendering

📏 Update 20250707: I have uploaded all the .3mf files for printing in PET. You have to select your own material brand. 
Also I have uploaded a pdf file with instructions, in german, on how and in what order to assemble the parts. When you want it in english just let ChatGPT translate it for you.

📏 Update 20260503: Here are two versions of the same design The one in the back was printed in coloured PLA, and this is the result after one summer outside.
In the foreground the one printed with white PETG and before assembly the parts were sprayed and painted. This summer we will see how the PETG version will hold up.

📏 Model Dimensions
 

Approx. 60 × 42 × 33 cm (L × W × H)

The model echoes the traditional Valais architecture of the original, including:

• Timber-frame construction

• Concrete base

• Tiled roof

•  

🔧 What to Expect

This is a large, visually impressive project — easy to print, but extensive in scope.

✅ ~95 printable parts, each sized for a Prusa MK3 or MK4

✅ Multi-color capable without MMU (separate colored parts)

✅ Organized .3mf files with grouped small parts

✅ .bgcode files included for additional guidance

🧵 Filament Recommendation:

I used PLA because of the colours available in my workshop. 
For outdoor use, consider PETG or ABS for better weather resistance. 
I’m curious to see how PLA holds up outside!
 

Update 20250702: After a few days with +30 C and sunshine, PLA does not hold up very well.
See picture below.

Recommendation: Do not use PLA for outdoor use.    Now I am testing PETG.
  
 

🏗 Assembly Tips

All parts require careful gluing. 
For a smooth build:

🔹 1.8 mm alignment holes alignment use for short (≤5 mm) filament pieces. If necessary drill out the holes with a 1.8 mm drill

🔹 Ensure your printer is well-tuned — test-fit before you apply glue!

🔹 Misalignment? Alignment holes not matching? Double-check part placement and orientation

🧱 Wall Assembly 

For east/west walls: (4 parts plus cross support, see picture)

Glue left top and bottom to the cross-stud. Make sure everything is aligned well, no gaps. 
Then add the right top and bottom parts.
 

For north/south walls: (6 parts plus cross support, see picture)

• Glue middle sections to support studs. Insure there are no gaps

• Once the glue is hardened, attach upper and lower parts one by one

• Slide them into place and glue them to the cross support 

🏠 Roof Assembly (see picture)

• Glue three, north, matching roof parts together (in the picture group 1 ).

• Glue three, south, matching roof parts together (in the picture group 2 ).

• Glue the awe groups together with the roof strips. The roof angle is important!  

• The construction should be cured upside down, supported by two horizontal battens.

🔩 Final Steps/Tips

• Glue base parts last for added stability

• Once all fits correctly, glue in interior vertical corner supports

• Double-check shutter orientation (mirrored left/right)

• Use clear plastic behind windows for realistic glazing and insect protection

🖼  Roof canopies feature a color-change print effect — mimicking wood + zinc cladding. For this a color change is in the bgcode.

🎯 Want to Scale to H0?

You can try scaling the model down to 25% to print in H0 scale.

Options:

• Print all in one color and paint it. 

• Use an MMU for multi-color

⚠ Note: I did print it with PLA. It needs a lot of supports. Have a look at the .bgcode.
