Hello! Yes, there are some repaints of Gotheborg trams aviable here:
http://banbyggarna.se/msts/Trams.html
However there aren´t any Gotheborg tram route aviable, and no one is currently building it. However, Totte´s Oslo - Gotheborg route wich will be released sometime during 2011 will include about 2 km of the tram nework, if I´m not mistaking.
