works but does have a problem with the train falling off the track, I didn't spend the time to find a solution.

How did anyone solve friction (or lack there of, to be precise) problem? For me, the switch piece wobbles way too much, and most of the time train derails going through the switch, as the guide piece moves too easily.

When train goes left it gets stuck because the switch rail and the guides of track ar too thick.... there is not much space for the wheel of train to pass on turn.

the one in picture had following settings:
20% infill
0.24 layer height
45 mm/s perimeter speed
80 mm/s infill speed
curaEngine slicer
printed from 3mm PLA
print time around 2 hours

What settings do you use?
