What if Spain’s transport system were a metro transit map?
One possibility is shown above. Spain’s transport structure inherited the radial distribution, centered in Madrid, from the ideas of the 19th century when trains expanded, and later in the 20th century, with cars. Seven lines go from the capital to the corners of the peninsula: A Coruña, Irún, Girona, Valencia, Cartagena, Cádiz, and Badajoz.
Other lines follow the coast: dark pink along the Mediterranean and purple and dark blue in the Atlantic. Some lines are very short like the light blue towards Ávila.
Which line is your favorite? Should we redraw them? How would you trace it?
