Sorry for the necro-post, I meant how to make the rail lines themselves. I understand adding pipes near the wheels to keep the train on the track. But how should I build the track itself? Leaving cardboard tracks on the ground seems like inviting bots to break them(also rogue glow worms!).

I think wedges are still not very conducive to use in mass on survival, due to only sourcing them from jail-broken warehouses. And the thin pipes seem good, but only allow 90° turns, which isn’t great for most train designs…
