About the Noord Zuid Lijn: i really think that instead of finishing of the line and having subway trains running somewhen past 2015 they should just finish the tunnel and then turn it into a super deluxe underground bicycle express-path. The tunnel would dramatically cut down the time needed to get to the center, prevent you from rain and would probably be used by more locals on a daily basis than a subway ever will. The thing needs to have lots of smooth on- and off-ramps that connect it to the cross streets and of course tourists need to be prevented from using it.
