Freiburg trams between 1990 and 1997

Compilation of several VHS video tapes depicting the Freiburg system during the period of transition from high-floor GT8C and GT8N (Niederflur) trams to cars of a unique (to Freiburg) low-floor design, classified GT8Z (Zwei-Richtung). The three 4-axle 'Sputniks and nineteen GT4 cars were still in evidence, including some purchased from Stuttgart, but they gradually decreased in numbers with the arrival of the new trams. My apologies for a couple of breaks in the sound; this was due to my cutting my poor commentary several years ago.
