The minecart rail can be broken instantly by hand.
It drops as an item if there is no block beneath it to support it.
If there is no block beneath a rail, it will break and drop as an item. If there is any type of rail one block towards either side and one block up, it will change its texture to appear connected to that rail. It allows entities and the player to walk through it, very much like a crafting table. However, minecarts float slightly above the rail.
The minecart rail allows the player to move faster using a minecart, because it moves quite slowly on regular blocks. The player can accelerate on rails using gravity by going downward, or by using powered rails.
