Dortmund Mobile

With the projects Line 400/401, CityTaktPlus and DOnight, Dortmund is taking its local transport to a new level.

Whether quickly from Hörde to Borsigplatz, reliably home at night or to work every 5 minutes - with Dortmund Mobil we are starting a new era for local transport in the city centre. The new concept offers shorter intervals, better connections and new links - reliable, electric and well-connected throughout the city.

More frequency. New lines. Better connected.

Line 400, CityTaktPlus and DOnight make Dortmund Mobil.

With the Dortmund Mobil project, the City of Dortmund and DSW21 are improving local public transport in a targeted and sustainable way. The new Line 400 connects central city districts such as Kreuzviertel, Hauptbahnhof, Borsigplatz and Kaiserviertel every 10 and 20 minutes - conveniently, directly and without changing trains. It is supplemented by line 401, which runs in a clockwise direction and completes the ring.

The CityTaktPlus provides more frequent service on busy light rail lines - in future even every 2 minutes on some sections. This means shorter waiting times, better connections and more reliability in everyday life. With DOnight will also significantly expand the service in the late evening and at night - both on the railway and with electric night buses. The result is a mobility service that is reliable, climate-friendly and suitable for everyday use - for the whole of Dortmund, around the clock.

What are the goals of Dortmund Mobil?

More flexibility

Closer intervals, new lines and an extended service provide more flexibility when planning your journeys.

More sustainability

More and more vehicles are going electric. This makes travelling by bus and train more sustainable and quieter.

More mobility

A better connection to regional and long-distance transport makes travelling more comfortable and offers more mobility thanks to P&R.

New campaign flanks recruitment drive

DSW21 has already taken on almost 120 drivers this year. And that is far from the end.

DSW21 is getting serious! The transport company is continuing its recruitment drive for the mobility turnaround in Dortmund and the implementation of the Dortmund Mobil concept with the three components DOnight to optimise night-time public transport services, CityTaktPlus to increase the frequency of services on heavily frequented light rail sections and "Line 400". A new campaign is currently underway with radio adverts on 91.2 and poster motifs.

"Make yourself and our environment happy: with a job with us." DSW21 is using this appeal to recruit new drivers for both the bus and light rail sectors. The message is clear: as an employee, you are part of the mobility transition and make an active contribution to climate protection. So you're not just moving people from A to B, you're also making a sustainable difference.

The most important facts in brief

Questions and answers about Dortmund Mobil

Dortmund Mobil is a project organised by DSW21 together with the city of Dortmund. It aims to noticeably improve local transport in the city centre with targeted measures, further develop the city's public transport system and make it more attractive for everyone.

Dortmund Mobil consists of three sub-projects: Line 400, CityTaktPlus and DOnight, which include an extended light rail service and more night-time journeys.

The new bus routes 400 and 401 connect Dortmund city centre in a ring service. They run every 20 minutes, and in the core section there is a dense 10-minute interval. Lines 400 (clockwise) and 401 (anti-clockwise) automatically change numbers at the end points - there is no need to change buses. With the new lines, the 452, 455 and 456 will be cancelled, and the 453 will take over the direct connection from Schüren to the main station. In addition, bus stops will be made barrier-free and bus lanes and cycle lanes will be installed.

A concept for increasing the frequency of light rail services:

  • Between the main station and the harbour (U47/U49): every 5 minutes
  • From 2026 also on the U41 between Fredenbaum and Hörde

This will noticeably improve punctuality and connecting services

In future, the light rail will also run at night - initially at off-peak times and later expanded. In addition, night bus lines with electric drive will be in operation, reducing emissions and noise.

The start is 27 October2025.

The line operates in a continuous ring service, running every 20 minutes as such. New sections to Hörde and Märkische Straße, also every 20 minutes, will also be integrated into the concept. Between Stadthaus, Kreuzstraße, Hbf, Borsigplatz and Funkenburg, the services overlap to form a uniform 10-minute interval.

 

The subdivision is primarily intended to help our customers:

  • Journeys on route 400 with destination "Stadthaus" travel the ring in an anti-clockwise direction. At "Stadthaus" they change to route number 401 and continue to "Funkenburg".
  • Journeys on route 400 with destination "Funkenburg" travel clockwise along the ring road. In addition, the sign "Ringverkehr" is displayed on the buses - so it is clearly recognisable that no change is necessary.

 

  • The existing line 452 will be replaced by the ring lines.
  • In future, the new line 453 will run directly from Schüren via the Kaiserviertel district to the main railway station. Many destinations will remain accessible - often even more directly or more frequently.
  • Lines 455 (Dortmund Hbf - Hörde) and 456 (Dortmund Hbf - Schüren) will be completely cancelled and replaced by the new line 400.
  • Lines 412 and 451 will be adapted to provide a better connection to the new 400.

 

Some of the direct connections will change. Line 452 has been cancelled, but:

  • Line 401 will continue to connect the neighbourhood every 20 minutes in a circular service.
  • The new line 453 provides a direct connection to the main railway station.
  • The bus connections to the light rail every 10 minutes will be retained.

Until the start after the autumn holidays:

  • New bus stops will be installed (temporary/barrier-free)
  • Bus lanes and cycle lanes marked
