As for me having to repeatedly jump to get the lightbug to move, I can tell that it is a func_tracktrain which has three entities parented to it.
Try making the platform force it's movement, I believe it stops because the player is in the way of the thingy on top.
When on the settings of a func_tracktrain, there is no such option.
I tried "No User Control" to no result.
