I generally put a little bit of ballast texture underneath my tracks so the transition between track and roadbed isn't quite so abrupt (just a little, mind you, I use the smallest diameter "brush"), but it is HIS route, he can do what he wants!
Personally, I think it looks just fine the way he's doing it. Keep up the good work!
