Jena, May 29, 2026. A months-long structural turning point is imminent at the central transport hub Paradiesbahnhof: Starting June 29, 2026, the tram line there will be completely renewed in three complex sections. As this is one of the most heavily used routes in Jena’s local transport network, commuters must prepare for extensive restrictions and comprehensive rail replacement services.
- What: Complete renewal of the tram line (rails and substructure)
- When: Start on June 29, 2026, planned end in spring 2027
- Where: Paradiesbahnhof area, Jena
- Restrictions: Interruption of tram lines, rail replacement service (SEV) with buses
Rail Network at its Limit: Why the Renewal is Unavoidable
The tram network around Paradiesbahnhof is one of the absolute lifelines of Jena’s infrastructure. Every day, hundreds of trams roll over this section to transport passengers from populous districts like Lobeda and Winzerla to the city center. After around three decades of continuous, intensive use, the rails and, above all, the underlying concrete foundation have reached their wear limit. The damage underground can no longer be fixed with provisional repairs.
A fundamental renovation is essential to ensure long-term operational safety and noise protection in urban local transport. By renewing the track, Stadtwerke Jena is investing in a sustainable rail network that will withstand the requirements of modern low-floor trams and increasing passenger numbers in the coming decades.
Massive Impact on Commuter Traffic
Paradiesbahnhof forms the central transfer point between Deutsche Bahn’s regional rail passenger transport and urban local transport. Thousands of commuters and students arriving daily at Jena-Paradies station rely on the direct tram connections. Due to the full closure of the affected section from June 29, this direct chain will be temporarily interrupted.
The closure requires a large-scale restructuring of the entire line network. Passengers must expect significantly longer travel times and additional transfers. Significant capacity bottlenecks are expected, particularly during morning and afternoon rush hours.
Rail Replacement Service (SEV) in Detail
To ensure the mobility of citizens and commuters, a high-performance rail replacement service with buses will be established. Transport planners have developed the following concept:
- Replacement buses: The closed tram sections will be served by articulated buses to handle the highest possible passenger capacities.
- Route: The replacement buses will run at high frequencies between the city center (Holzmarkt/Teichgraben) and the southern districts.
- Stops: Nearby replacement stops will be set up within walking distance of the DB station Jena-Paradies.
Despite the high frequency, commuters are strongly advised to check Jena’s local transport digital information systems before starting their journey and to plan for additional time buffers.
The Three Construction Phases until Spring 2027
The major construction site will be realized in three staggered construction phases to minimize disruptions to individual and local transport as much as possible:
- 1st Construction Phase (from June 29, 2026): Start of the main work directly in the intersection area of Paradiesbahnhof with initial track dismantling.
- 2nd Construction Phase (Autumn 2026): Civil engineering work on the rail foundation and laying of new track briquettes as well as adjustment of the stop areas.
- 3rd Construction Phase (Winter 2026/Spring 2027): Final asphalt work, overhead line installation, and subsequent test and acceptance runs before commissioning.
🚗 Traffic & Everyday Consequences: Paradiesbahnhof as Jena’s Lifeline
The Paradiesbahnhof stop not only links urban tram and bus traffic but also acts as a direct gateway for commuters from the surrounding area (including Erfurt, Weimar, Naumburg, and Saalfeld) via the adjacent DB station Jena-Paradies. Tens of thousands use this transfer point daily. During the construction period until spring 2027, commuters must switch to the rail replacement service (SEV), which will be routed via parallel main traffic axes such as Stadtrodaer Straße (B88) and Knebel. Local drivers are strongly advised to bypass the area widely, as traffic delays are also to be expected.
