Krakow
LRT subway, tram, planned metro

Light Rail

Krakow's first tramwaje opened in 1882. It now has 28 lines covering a 86.5 km. 

The 4 station subway section of Krakow's light railway opened in December 2008.  The tram line is known as the "Fast Tram", as opposed to Krakow's other streetcars, perhaps known as slow trams.

Metro Plans

In 2009, plans for a two line metro were announced. This wouldn't be the first time Krakow planned for a metro. Plans in the 1970s and1980s actually produced several tunnels under Krakow which are now part of the new tram tunnel. The section under the railway station was built in 1975 in the event a metro might be built. The section under Lubomirskiego Street was built in the 1980s, and the far eastern and western sections of the tunnel were built in 2000.

Since the majority of the existing tunnel has been built to light rail (stadtbahn) standards, speculation of a new metro bypasses the existing tunnel, leaving it for it's current use for light rail and streetcars.

Construction is scheduled to begin soon on a new 4 km light rail line, with an opening in 2012.
