railroad tracks.
The plural of track is tracks. For example: The train crashed as it came off the tracks.
This is an example of indirect observation, where evidence of animal presence is inferred through the tracks left behind rather than directly observing the animals themselves.

buckled railroad tracks on a hot day
One example of a difficulty caused by thermal expansion is the buckling of railroad tracks during extreme temperature changes. As the tracks heat up, they expand, but if they cannot move freely due to constraints, it can lead to bending or buckling of the tracks, which can disrupt train operations and pose a safety risk.
I believe car tracks are the evidence that the car's tires leave behind. So for example the tracks left behind in the mud, or in the snow, or even the burnt rubber tire tracks from accelerating too quickly.
A good example is animal tracks. You may see, for instance, paw tracks in the sand. You did not see the dog that made those tracks, but you know he was there because the tracks are there. In this case you have indirectly observed the dog.
A simple everyday example is the gaps left between sections of train tracks to account for expansion due to heat. As the metal tracks heat up, they expand and can increase in length. The gaps prevent the tracks from buckling or warping by allowing them room to expand without causing damage.
The noun tracks is the plural form for the singular noun track.The singular possessive form is track's.Example: The track's surface needs repair.The plural possessive form is tracks'.Example: The railroad tracks' direction is north and south.)
