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.
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.
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.
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.
The way a person can keep their train from jumping the tracks is to make sure the tracks are well maintained. This means the tracks should always be on a level and cleaned surface so that nothing gets between the rail and the train wheel.
