The Mission station is just like it is now (or not, if you prefer). The map doesn't show commuter rail, only lines that would be operated throughout the day in both directions.

The Central Valley alignment allows for many additional connections over the current alignment along Burrard Inlet:
@Braid station: New West, Lougheed on skytrain and Surrey (could be a direct line or with a transfer) on regional
@Still Creek/Willingdon: Metrotown, Brentwood, and North Van on B-lines
@Commercial/Broadway: Broadway and UBC on skytrain

Combined with a line to Surrey, it also decreases the total length of track in use for regional lines over also using the Burrard inlet alignment. This alignment is also straighter, so it would have a higher operating speed. And it allows for better separation of freight and passenger lines. The right-of-way is wide enough to have a separate track for freight to North Van.
