The busiest line of the Leipzig tramway network is served during weekday daytime hours every 10 minutes, and every 15 minutes at other times. "Bombardier Classic-XXL" stock, each with the capacity of a three-car Tatra formation ("Tatra-Großzug"), entered service from 2005 / 2006. Because only 12 Bombardier vehicles are on hand (at 2006 July), Tatra formations with low-floor trailers also serve this line, especially on weekdays. The line connects the large housing estates at Miltitz and Grünau-Nord, as well as the densely populated districts of Lindenau, Thonberg, Probstheida and Meusdorf with the town center. At the Moment the Line works only with the "Bombardier Classic-XXL" stock.
