Very very simple. The rail is held in by just two screws. Remove these, remove the old rail, replace with new rail, screw it down! The hardest part is actually getting your head into the space where the drawer goes so that you can see the screws you're removing.
Now, why this thing broke to begin with is a whole other story....but at least fixing it is simple.
