How can I get this Cylinder to snake along this spline path.... looking for help or a tutorial

Here is a better example of what I am looking for…maybe you can point me in the direction of a tutorial i can use… I want a spline that curves …i will use this spline as a track…on this track i want to use a cylinder object to be attached to the center over this spline… as the cylinder moves along this track I want it will conform to the tracks bends and curves … basically i want the cylinder to snake along the path… below is a link of what I have done so far [spline]
