The download package only contains the assets needed to make the route. It contains none of the scenery, tracks, buildings etc.   This is a delibrate decision to seperate these out so that you do not need to download all of them again if the route update is minor or, conversely, download the route if you just need to use one of my assets.  It makes the download process more fiddly for a first time download but thereafter makes updating really easy.   My asset packs are the RMrailworks / Richard Maxted ones found on this website.
