Hi,
this is my new model of diesel locomotive type 742 called “Tomcat” (I dont now why), which is used for mainly freight transport. The model is in the scale 1:25 and it’s possible to use it on garden railway in G-scale (designed for PIKO 36105 carriages). I drawed it from scratch in Sketchup 2020 Pro and printed on Prusa MK3S printer.
Here are some pics of WIP, visualization and final photography…

Amazing work!
I love it!
Superb workmanship 
Absolutely fantastic! I’m amazed the Prusa MK3S can make those pipe railings or some of those textures.
Just Gorgeous !
This is fantastic work!
Thank you all!
The railing on the sides is divided to plannar parts and the railting in the front and back is printed with overlaps around 30° and with local supports.
Fantastic! Only, adding the rust and the dirt will be a tough job!
Congratulations. This is fantastic! Looks like you have a great business opportunity here. Have you considered making these for others?
You’re right, this is a model made of colored filaments and now I’m printing another model made of PETG, which will be repainted, rusted and run on a G-scale garden railway..When it will be done, I’ll make some movie 
I offer the model for 3D print on my website. But the instructions are only in czech but I think the assebly is pretty easy and there are many pics. If you want, you can visit https://www.mikibroz.cz
Can’t wait to see that!
Here is the video which I made about process…But I rather leave rust and dirty out :-).
Awesome! And also beautiful without the rust and dirt
Very nice work and a nicely made video - well done 
This looks fantastic! I’ve tried printing larger train bodies on my MK3S before using PLA filament, and I sometimes struggle with slight warping on long flat panels—especially if the ambient temperature isn’t stable. Did you run into anything like that while printing the chassis or side walls? Designing the whole thing from scratch in SketchUp is no small feat!
Thank you.
Yes, this can happen if the printed parts do not adhere well to the heatbed. This can be caused by large parts or f.e. even a small contact area between the printed part and the heatbed. For best results with PLA, I use an adhesive spray, such as 3Dlac.
I think, 3Dlac is the best way to get great results with large prints from PLA. Some people also use hairspray or stick glue like Kores but I didn’t try it :-).
