Train Tracks Complete Set v4 (reversible)

thingiverse

I've redesigned all the track pieces so they can be easily turned upside down (top to bottom). Any part with a curve or a slope has been re-engineered to accommodate reversals. Be aware that you may need to add some additional support, depending on your 3D printer's capabilities, for certain parts. Others will absolutely require it, like the hills, which have steep inclines that demand extra reinforcement.
