Rails are made of iron and will rust over time if there is no rail traffic over the rails for an extended period of time. Rust is caused by oxygen and water and other components getting to metals that it reacts with. This applies to train tracks too.
Steel, light weight, stainless, sturdy, it will not rust and the lead to civilians dropping onto the tracks, or worse into the path of a train.
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.
They can rust over time, especially if they are subjected to very acidic environments. If you live near train tracks, a body of salt water, or you live in an area that is subject to high levels of air pollution, then yes, they can rust over time.
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.
