From your last sentence it looks as if you are trying to use Olegkhim's wireable points. They are similar to Andi06's ones in that you have to add the internal invisible track to make the junction (think of them as an animated scenery item superimposed on a normal junction). If you do this then when you go into driver the points blades will automatically appear. If you want a tutorial do a search on Andi06 for a link to his website (I haven't got it to hand at the moment).
