16: Gastfeldstraße - Brill - Bahnhof - Wachmannstraße The system suffered severe damage during World War II - tram services were abandoned on 22 April 1945. After WWII had ended, only 10% of the rolling stock was in working order, and 80% of the overhead lines had been damaged. World War II aftermath On 13 June 1945 the first tramways resumed operation. In the immediate aftermath of WWII, the Bremen network was split in two, as the bridges over the river Weser had been destroyed. In 1947, the two parts of the network were reconnected, and apart from the tram line over the Stephanibrücke, the 1950s BSAG network re-attained its pre-war extent. In 1953, bus traffic was taken over by the BSAG. The new Flughafendamm workshop near Bremen Airport was constructed in 1959; in 1963 the head offices also moved to that site. In 1965, the main passenger transfer stop was relocated from the Marketplace to Domsheide. Bremen Tram Riots The Bremen tram riots in 1968 (alternatively often referred to as Bremen tram riots or large student uprising) lasted from 15 to 22 January 1968 and were superficially against fare increases of the BSAG. However, they also reflected the youth's desire for more self-determination and the rejection of the Vietnam War that was being waged at the time. During the riots, serious violent clashes between the demonstrators and the police took place in the inner city of Bremen. Ultimately, the fare increases were withdrawn. The Bremen tram riots were part of the nationwide '68 movement, which called for more participation and democracy in society, businesses and educational institutions, protesting against the authoritarian leadership of a rigid state apparatus that demanded more and better schools and universities and condemned the Vietnam War. Also in Bremen 1965 and 1967 student demonstrations took place against the educational emergency. A Vietnam committee organized rallies and information sessions against the war. In 1967, the schools were more and more involved in these protest movements. To improve the self-determination of the schools existed the "Arbeitsgemeinschaft Bremer Schüler" (ABS) as an association of class and school spokespersons of all Bremen schools. It was the student's mouthpiece recognized by the Senate. However, some of the Bremen students felt that the ABS was insufficiently responsive to their work, and allegations were voiced that they largely shared and represented the interests of the Senate, which financially supported the ABS, such
