In Europe, a handful of metropolitan areas are leading the way with public transit projects that are making their cities green, rather than gray. In France and Spain, new train lines have been installed that are beautifying cities by creating greenbelts, rather than taking them away. By installing turf between and surrounding the actual train lines, these cities are not only solving traffic congestion, but also (thanks to the turf ) solving noise pollution and making the landscape look a whole lot nicer. In 2006, the first new tramway to be built in central Paris for more than 60 years began operation. An eight-kilometre line, running through the 13th, 14th, and 15th arrondissements south of the River Seine, the Tramway de Marechaux Sud (TMS) links the Pont de Garigliano on the city's western edge with the Porte d'Ivry to the southeast. The TMS is the result of the growing need to increase public transportation capacity in Paris. But, the city leaders did not merely want to build rail lines and stations; they wanted to create something that would help improve the surroundings. Thus, the TMS is just one part—albeit a major one—of Paris Mayor Bernard Delanoe’s traffic-busting, anti-pollution promise to “green” transport in the French capital, and also reduce the noise levels associated with traditional gravel and concrete rail lines.
