Ulm Tram Line 2 is the second metre-gauge tram line under development in the city of Ulm, Baden-Württemberg, Germany. It will connect the Science Park in the north with the Kuhberg residential area in the south-west of the city.

The new line will serve the increasing transportation needs of Ulm city, which is one of the fastest growing economic regions in Germany.

The Ulm city council approved the construction of the project in May 2015. SWU Verkehr, a subsidiary of SWU Stadtwerke Ulm / Neu-Ulm, is responsible for the planning, construction and operation of the project.

Construction of the new tram line will begin in the second half of 2015, the first phase is scheduled for completion by the end of 2017, and commissioning is expected in summer 2018.

Purpose of the new tram line in Ulm

Braunschweig (Brunswick), Germany, is the focal point of a projected tram-train operation covering a large area in the east of Niedersachsen (Lower Saxony).

Increasing transportation needs of the city’s population has called for the introduction of additional public transport services in the city. The route is used by approximately 16,000 people a day, including employees and students. New establishments and extension of Science Park are expected to further increase the ridership in future.

To address these issues, the SWU decided to expand the tram network in the city. Addition of a second line was found to be a feasible and profitable option, after considering all the socio-economic and environmental aspects.

Ulm tram line 2 project details

Design and planning approval process for the project began in March 2011. The new line will be 10.5km-long and include 20 stations. Sharing of the existing infrastructure of line 1 reduces the new track construction to 9.3km and the number of new stations to be built to 18. The new line will add a passenger capacity of 8,000 a day.

The project further includes the expansion of the transport depot in Ulm Weststadt to accommodate additional tramcars and the construction of a 400m-long bridge over the rail tracks at Kienlesberg that will be used by trams, buses, pedestrians and cyclists.

Construction on the first section of the line and the depot expansion will take place initially, which will be followed by groundbreaking of the second section in late 2015. The first new tram is expected to be delivered in mid-2017 and the line will be commissioned by the end of 2017.

Ulm tram line 2 route

The new line will originate at Science Park II and pass through Lise-Meitner-Street, Hochschule Ulm, Manfred Börner-Street, University West, Kliniken Oberer Eselsberg, Botanical Garden, University of South, and Eselsberg Hasenkopf, as well as Multscher School, Teachers Valley, Karlstraße / SWU, Theater, Hauptbahnhof, Ehinger Tor, Martin Luther Church, Romerplatz, Saarlandstraß, Grimmelfinger way and CTCs Königstraße to finally end at Kuhberg Schulzentrum.

Rolling stock

SWU Verkehr ordered 12 Avenio M low-floor rail vehicles for the new line in May 2015. Siemens and SWU signed a $35m (€32m) agreement, which also includes an option for the supply of six additional trams. The first delivery is scheduled in mid-2017 while the final delivery will take place in spring 2018.

Siemens will manufacture the trams at its manufacturing plant in Vienna, while the bogies will be manufactured in Graz. Siemens’ Nuremberg factory will deliver control and traction drive technology for the trams.

"The new line will serve the increasing transportation needs of Ulm city, which is one of the fastest growing economic regions in Germany."

Avenio M supplied for the Line 2 will be a 31m-long, five-car, low-floor light rail vehicle with a capacity to accommodate up to 175 passengers. The lightweight aluminium body of the car, coupled with state-of-the-art drive and control technologies, reduces energy consumption and operating costs.

The interiors of the tram are designed to be transparent to enable safety and comfort to the passengers. The spacious interiors and larger doors further improve the passenger circulation. Each vehicle will feature a different front and rear design coloured in blue, light-gray and white and every bogie will feature the name of a historical figure related to the city of Ulm.


The total estimated investment of the project including that of depot extension is $213m (€192m), of which $12m (€11m) will be spent for the expansion of the depot.

In June 2015, Baden-Württemberg State Government submitted a funding application to the government of Germany for $74m (€67m) to finance the project. The city of Ulm is expected to provide approximately $59m (€53.3m) for the project.
