The network is currently operated by Bremer Straßenbahn AG (BSAG; Bremen Tramways Company Ltd.), and integrated in the Verkehrsverbund Bremen/Niedersachsen (VBN; Bremen/Lower Saxony Transport Association).

[2] Several sections have been brought to light rail standard, including viaducts, especially on the lines to Osterholz, Arsten and Huchting.

Once the exhibition had ended, the overhead line equipment was removed, but the system had worked so well that it was decided to electrify all tramways.

Electrification was implemented by Union-Elektricitäts-Gesellschaft, the German subsidiary of the American Thomson-Houston Electric Company starting in 1892.

[7] By 1939, the network consisted of the following lines: The system suffered severe damage during World War II - tram services were abandoned on 22 April 1945.

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.

Against the editor of the newspaper The echo of the Gerhard Rohlfs high school in Bremen Vegesack, Hans Jürgen Weissbach, was determined because of offense against the press law.

Rudi Dutschke, a representative of the German student movement and the Extra-Parliamentary Opposition, visited the city and gave two speeches.

On 23 December 1967, in Bremen, a large demonstration against the Vietnam War with several thousand participants took place.

On the afternoon of Christmas Eve, the USB distributed leaflets in front of two churches, telling churchgoers to visit the "rich devotions" while "the war raged in Vietnam."

Morally and logistically, they were supported by the leftist SPD Altstadtverein (OVA) and the then FDP-affiliated Young Democrats.

On Monday 15 January 1968, around 5 pm, a group of 25 to 50 students, young trade unionists and apprentices gathered on the Domsheide in front of the bell to demonstrate against the fare increase.

Although the trams had to stop their journey and the urban transport in the downtown area collapsed in part, but after about an hour, the students were pushed by the police, and some were carried away.

The next day, Tuesday, the 16th, the protesters received further inflow and soon gathered in the afternoon, a crowd of 1500 people, the signs with inscriptions like "70 Pfennig - I prefer running" waving.

The backwash of the forced to stop trams and buses extended in the south to the new city and in the north to the station, which corresponds to a distance of 1.1 kilometers.

Finally, the police intervened again, but the blockers were not carried away without resistance as the day before, but threw stones, firecrackers and paint bags.

When a large group of students attempted to storm the Domsheide, the police put this slogan into action and beat down the demonstrators with batons, injuring numerous bystanders.

After the works councils of the AG Weser and Klöckner Hütte, the two then largest employers in the city, declared their solidarity with the demonstrators on the morning of 18 January, some 20,000 people gathered at the Domsheide.

Railway tracks and entire streets in the Bremen city center were occupied and blocked, detonators ignited and slogans such as "Beat the cops dead" called, after which the police took 138 protesters into custody.

The President of the Senate and Mayor Hans Koschnick (SPD), who had not held his post at this time for two months, agreed with the organizers of the student protest on a conversation on 19 January.

Bremen Interior Senator Franz Löbert (SPD), on the other hand, had proposed that the tracks and roads be taken back by force.

In addition to Koschnick, the senator for seniors and mayor Annemarie Mevissen (SPD) and Rolf Seggel, the chairman of the board of BSAG, were present.

Only on Sunday 21 January were still reported some small clashes between protesters and security forces from Bremen North.

On the contrary, students at the engineering school even canceled a demonstration against police crackdown during the past week.

After that, the Bremen Parliament met in a special session; it decided to set up a parliamentary committee of inquiry to investigate and assess the behavior of the security forces.

In addition, the mayor explained that the road toll, as discussed with representatives of the demonstration parties, would be lifted for the tram.

After the meeting of the citizenship announced Koschnick on Wednesday 24 January, the decision taken in front of about 4,000 people on the Domshof and regretted at the same time the events during the week.

The protests began on 6 December with a major demonstration against school abuses, which also denounced the ticket price increase.

A possible future variant would be a similar but bi-directional, dual-system vehicle that could also be used on DB tracks and so could connect BSAG's inner-city tram network with railway lines.

Of the 61 trams and 57 trailers originally delivered, four GT4f vehicles are still in service, though limited to driver training purposes and other special occasions.
