The second mission in the Amsterdam scenario involves running a tram server all the way to Schiphol. Nevermind a station-Schiphol airport service was the very first thing I did. sigh
Anyway, I can't actually make this happen because I can't close the line. To make a loop, buses can simply use this roundabout. The game would just like trams to cut through the roundabout, but that means there's no way for trams to change direction of travel and turn back.
How can I make this happen?
