This is a classic christmas gift, a toy train with train tracks.
With the freedom of 3D-printing there´s no end to how you can make your own railway. 3D-print as many tracks and locomotives as you like and build your own railroad.
Even though this is a toy train set the track size folows the standard size for H0 trains (1:87).

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
