Question about Cars & Trucks
Here's one reason: Railroad tracks are made of steel which expands and contracts with temperature variation. If long straight sections of track don't have expansion joints in them (which they usually don't due to the continuous ribbon rails they use today) then expansion or contraction needs to be taken up by the nearest curve. Otherwise the track can experience "heat kinks" where the rails buckle upward. Very long straight sections are a problem in this regard so adding curves alleviates it. One other reason is that rail lines follow contours that offer very shallow grades. Trains don't do well on hills.
