Moving objects along a dynamic path

Hi all,

I am new to this particular technologies so bare with me if I sound silly...I am trying to simulate a train moving along setions and I figured I could do this with WPF and C#...I have a message Queue which will be monitored and if a train moves from one point to the other, my train will move along the path accordingly.

Before complicating it this would get me started...I have managed to move an ellipse around but i would like to know how to do this task in a more organised way...please help or point me to a good tutorial.

Many thanks
