Summary

How do trains turn. This print demonstrates how. The model is similar to that used in the attached video https://www.youtube.com/watch?v=HeDuGWNTDPY&t=96s

Extra gear

glue
sand paper (i used 120 grit)

What to print

2x track legs
2x wheels
2x track
1x axle

Notes

I used white filament so the glue cannot be seen
when rolling the wheels down place the wheels straight on the track. It you don't it can derail
