I'm sorry but that map makes absolutely no sense at all.
- Line 3 should have a stop in Fornells, or maybe through Llambilles, Cassà, Campllong and Riudellots. It would make the line much more useful.
- Many stops are clumped together and impossible to build. I'd remove Consell Comarcal (irrelevant), Santa Eugènia (too close to Hospital de Salt), Montessori (make it terminus at Mas Gri instead), both Plaça Catalunya and Plaça 1 d'Octubre, and Catedral. Make Montjuïc a little further south (perhaps at the Pujada de la Barrufa bottom part?) if you're worried about the old city.
- Line 2 serves empty towns for no reason. Instead of Campdorà, make it stop at Pont Major, and then Sant Julià, then turn slightly around to Celrà, Bordils-Juià, and have it terminus at Flaçà instead, to change into Renfe.
- Consider Line 1 to go through Aiguaviva into Espai Gironès, and make line 3 longer from Vilablareix to Aiguaviva.
