This is a series of videos produced by a Chris Lyon who's videos are under his CNLVN nomenclature. This is far and away the best series on the Rio Grande Southern that I have seen and makes me want to get out of HO and go for Sn3. It appears that Bill Scobie is a very personable guy and I think you get pretty much a whole look at his railroad and how he builds things. There is also a Tutorial Guide done by Chris on painting Mountainous back drops. I don't know if I have watched every video as there are so many.
