Thanks to the extension, local transport in the north of Bonn will be significantly strengthened. In future, the light rail line will connect the Buschdorf industrial park as well as the center of Buschdorf. Stops are to be built in the area of Friedlandstraße, Schlesienstraße, the Buschdorf business park and Friedrich-Wöhler-Straße (Nordbahnhof). The streetcars that currently terminate in Tannenbusch-Mitte will then use the new route all day, every day, and will be able to transfer to the existing bus routes at all four new stops. The journey time from Bonn Central Station to the planned new stops will be approximately halved compared to the current bus connection.

The costs are estimated at around 31 million euros (2016 prices). According to an independent analysis, up to 4,200 passengers per day will use the new connection. As the population in the north of Bonn is growing, a higher number of passengers can be expected in the future, as Buschdorf is a growing district. Various projects are to be implemented in the coming years, first and foremost the sustainable, climate-neutral and car-free residential district "Im Rosenfeld", including a daycare center and elementary school. Other planned neighborhoods include Otto-Hahn-Straße/Kölnstraße and Schlesienstraße (Godau-Gelände/Petrusacker), which will benefit from a direct connection to the light rail extension.

The climate-friendly rail link can therefore make an important contribution to relieving congestion on Bonn's roads.

On January 15, 2025, the extension of the light rail line to Buschdorf/Auerberg was included in the public transport requirements plan and the public transport infrastructure financing plan by the Transport Committee of the state of North Rhine-Westphalia. This means that funding for the measure is possible in principle.

The regional council of the Cologne administrative district proposed the inclusion of the light rail project in the NRW public transport requirements plan and the public transport infrastructure financing plan at its meeting on October 11, 2024. Prior to this, the city administration had completed the preliminary planning and the results of the standardized assessment. The assessment resulted in a positive benefit-cost factor of 1.4, meaning that the benefits of the new connection for the general public are greater than the necessary investment costs.

A standardized assessment answers the important question of whether a project makes economic sense. Economically viable means that the costs and benefits of a project are considered for the general public - i.e. not only the consequences for individual groups such as residents or commuters, but also, for example, environmental consequences that affect everyone. On the other hand, a standardized assessment is the basis for the city to apply for funding from the state and federal government under the Municipal Transport Financing Act (GVFG) to finance the infrastructure.

In September 2020, the Bonn City Council commissioned the city administration to carry out all planning, technical and legal steps, a cost-benefit analysis and a standardized assessment as a matter of priority. A possible extension of the light rail line to Auerberg and/or the streetcar line 61 towards Buschdorf, which currently ends at the corner of Pariser/Kopenhagener Straße, should only be pursued as an option afterwards.

On Saturday, March 29, a dialog event on the extension of line 63 took place at the Am Apfelgarten elementary school. Residents along the route and interested citizens were invited to discuss the project with external and municipal experts. After a welcoming address by Mayor Katja Dörner and Anja Wenmakers from SWB, the project was presented. Participants were then able to discuss specific areas of the project at four themed islands. Citizens had the opportunity to express their ideas, suggestions and concerns on site. A drone video showed the future route of the light rail line from above and thus illustrated the project to the participants.
