Chemnitz–Leipzig upgrade project: Feasibility study paves the way for the upgrade of the northern section
The feasibility study sets out a solution that is both effective and financially viable: with targeted double-track sections where they are required to ensure frequency, capacity and operational reliability.
The study had become necessary after a cost estimate from DB InfraGO AG in February 2026 for a fully double-track upgrade, at 1.32 billion euros, was significantly above the approved funding framework. Against this backdrop, the parties involved agreed to carry out a robust assessment to identify an efficient and financially viable solution.
Specifically, the study proposes upgrading around 24 of the total 44 kilometres of the northern section to double track. The study estimates the cost of this at around 531 million euros. In addition to construction and planning costs, this amount also includes index-linking over the construction period and a risk buffer of 30 per cent to cover unforeseen costs. The existing funding mechanism under the Investment Act for Coal-Mining Regions (InvKG) is to be used for the double-track expansion.
The study estimates the cost of electrifying the line at around 149 million euros. This figure also includes, in addition to construction and planning costs, an adjustment for inflation over the construction period and a risk buffer of 30 per cent. This brings the total cost of the high-capacity upgrade, including electrification, to around 680 million euros. Funding for the electrification is to be secured through a grant under the Municipal Transport Financing Act (GVFG).
To secure full funding for the overall solution, the Free State is engaged in intensive consultations with the Federal Government, whose involvement is required for this purpose.
The Free State of Saxony has done its homework: we have held in-depth discussions with our partners on what a solution might look like, we have had this solution assessed, and we have found a viable way forward, including with regard to funding. There is now a solid foundation in place for an operational concept that has gained the acceptance of both transport operators, ZVMS and ZVNL, and for the double-track expansion between Leipzig and Geithain, which is the minimum requirement for this. We also have a plan for electrification: here, we will specifically seek funding through the GVFG. This is the approach we need: efficient, affordable and with a clear focus on what helps people in their everyday lives. I am extremely grateful for the federal government’s willingness to support us in this regard. I have vivid memories of the Parliamentary State Secretary’s visit in this context. We are engaged in constructive dialogue and I am convinced that, together with the federal government, we will take action.
In order to upgrade the line within the existing budget, the second track is to be constructed specifically on those sections where trains have to pass each other and where additional infrastructure is required to enable a more frequent and reliable service. According to the study, a second track is not strictly necessary on the remaining sections for the operating programme on which the study is based. Even with the adjusted scope of the upgrade, the half-hourly service for the RE 6 during peak hours between 6 am and 8 am and between 3 pm and 6 pm, as set out in the study, will be achieved. Outside these times, an hourly service is planned.
We’re finally on our way. The feasibility study provides us with a solid foundation for sustainably improving the rail link between Chemnitz and Leipzig. Even if not all our dreams and wishes can be fulfilled, the double-tracking of the line where it makes sense, electrification and increased train frequency are key elements. It was important to me that we find solutions which will bring about tangible improvements for rail users in the foreseeable future. Now, above all, we must stay on the ball and set the course, so that the findings of the study are actually put into practice. There is no guarantee of this, but I have every confidence that all those involved genuinely want to see this outcome realised.
