planned light rail

The Luxembourg tram was expected to be completed in 2002. Since then, plans have changed for the Mouse that Roared. As of January, 2003, a 14 km line is planned with completion circa 2006. In January 2004,  a 15 km line between the 'European' district of Kirchberg, northeast of the city, to Dommeldange and Gare Central was approved. It is expected to open in 2007 and use Saarbrücken style trams.
