I agree with Bunk on the station dots. They need to straddle both lines and should have an arrow indicating the direction of the stop.
I wonder if CT would ever consider doing a strictly horizontal, linear map. It would be cleaner than having it loosely reflect the actual geography of the city. NW and W could be the forks to the left of the map, downtown in the middle where both lines converge, and NE and S could be on the right.
If I'm a resident of the city, it will be clear that the south line is being represented for the sake of compactness. If I'm a visitor to the city and wanting to go to Chinook, for example, all that I'd really care about is the line colour (and direction based on the terminus station) and the stop name. I really don't need the map to physically represent that South = down.
