Move along a curve

I'm out of ideas how to make an object move smoothly along a curve. Thinking something along a train moving on rounded tracks or sliding on telephone phones. Would this require an additional plugin or is there something I'm just missing?

bump?

If you know the curve it is just maths.

Some easy curves can be done with a few easings, which can be done with scirra.com/forum/behavior-litetween_topic53288.html

Although it is not that easy to determine the parameters for the easings when you land on the middle of the curved surface. You could probably work with image points of the sprite for that and ease between them with a fitting easing mode (and control the position of the tween by your movement along the curve)
