Get angle between two offsets

[Captain Cody]

How would I get the angle between two x,y,z offsets? I'm working on a custom train track system for the map I am working on, and need to make the train point at the location it is heading. Meaning I need to get the rotation offsets between the train position and the track position.

Pretty sure this function will help (at least with the Z axis rotation) https://wiki.multitheftauto.com/wiki/FindRotation

Found that function, wasn't exactly what I needed because I'm using move object, but after mathing for a couple of hours I finally got it.
