Rollercoaster track position of Object and write to file

thanks for the reply guys!
Here is the solution i came up with. Not so clean but it kinda works:

the problem im having is that i can`t write exactly 60 datasets per second. Its more like 55 even through i write every 0.016667 sec into the file. Also how would i go about specific formating? Is it possible with the plugin to edit the string in a way?
