of the world — namely in Vienna, Amsterdam, and Brussels — while several other cities, beginning with Karlsruhe, have used mainline railway tracks to expand their tram networks. However, those cities are much larger and have gone further towards the development of trams into metro-style, heavier vehicles. It was therefore important for the Poznań administration to find out on their own how successful the program would be. As the program had proved successful, another new tram line started in early 2005, connecting the city center with eastern district of Rataje. It is not truly a fast tram, but the success of the first program has prompted the authority to convert an existing line into a faster one.
