Metal expands when it is heated. Since track is made of metal then it expands when it is heated by the sun.
train tracks or a railroad
Train tracks are magnetic.
Train tracks
You don't tie people to the train tracks. You can hogtie them and put them on the train tracks though.
If the tracks are not parallel, the wheels will not stay on the tracks; train wheels are spaced at a fixed width, or gauge, and that width cannot expand or contract to accommodate non-parallel tracks. Thus, if the tracks were non-parallel, the wheel would come off the track and cause a derailment.
Yes. Train tracks are metal because if they were wooden such fast moving train wheels will cause friction on the wooden tracks, setting them on fire.
You can acquire a cannon for your train on Spirit tracks.
Expanding on other previous answers:Tracks have gap because metal needs space to expand and contract. In summer the tracks tend to expand (heat leads to expansion). And in winter, tracks tend to contract.If no gaps were left than the two bars of metal will fight to expand and lead to cracks in the rail. This is the same reason why you see perfectly spaced cracks or divisions in sidewalks, bridges, parking garages, and buildings.Ultimately, tracks have gap for safe expansion of the metal.Read more: Why_do_tracks_have_gaps
Railroad tracks are made from steel.
Sure, make the train tracks from materials that (in total) are lighter (less dense) than water. Presumably you want the train tracks to support a train as well; in that case, the weight of a certain piece of train tracks, plus the total weight of the train, should be less than the weight of the water displaced by the train tracks.
People walk on train tracks for different reasons. Some people walk on tracks because it's a shorter distance to get where they are going. Some people may walk on train tracks because they enjoy the quietness of the paths that the train runs along. We used to walk the tracks when I was a teenager because we picked the raspberries that grew along the train path.
