One of my projects in the 3D Printing world is to design and print a train; Train Engine, Coal Car, Passenger Car, Cargo Car, etc.    I am not particularly into trains, but I thought it would be a fun project.  I’ve based the size of the train after Gn15 Model Train scale.  It specifies a train track gauge of 16.5 mm.

Only two of the cars have been completely designed and just finished printing the Train Engine, after several false starts.  The train is not a copy of any one train.   I used components I liked from many trains and incorporated them into the design.

A colored version of the Train Engine can be viewed on Tinkercad link: Train Engine.  Minor modifications where made for a successful print of the train.  The train was printed using supports (everywhere settings).  The carefully removal of the supports took time.

The wheels of the train were printed separately because I wanted them to be able to spin.

I even put chairs and gauges in the car to give the train character.  The grid on the platform was not part of the designed.  It was remnants of the support structure.  Instead of smoothing it out, I thought is provided a nice effect.

Train Engine:

Print Time: 3 hours 53 minutes
Filament: PLA – 4.11 meters 33 grams
Layer height: 0.1 mm
Shell Thickness: 0.8

Object Size (W, D, H): 33.468, 151.55, 60.503 mm

Wheels:

Print Time: 55 minutes
Filament: PLA – .45 meters 4 grams
Layer height: 0.1 mm
Shell Thickness: 0.8

Once I completed the entire train, I will make the .STL files available on youmagine.com.
