Germany invests €1.65 billion to upgrade Troisdorf–Wiesbaden railway reliability
The German government has revealed plans for a major upgrade of the Troisdorf–Wiesbaden railway corridor. The €1.65 billion project aims to improve reliability rather than increase the number of trains. Construction is set to begin in July, with work focusing on fixing long-standing infrastructure issues.
Work along the Rhine’s right bank will start on July 10 and run until December 11. The project targets weaknesses in the existing network to reduce delays and service disruptions. Deutsche Bahn will contribute around €70 million of its own funds toward the total cost.
An economic assessment found that this upgrade delivers slightly better value than alternative solutions. The projected benefits amount to at least €10.4 million. The focus remains on boosting performance and stability for passengers and freight services. The full budget includes a contingency reserve, ensuring flexibility for unexpected challenges. Authorities have stressed that the goal is not to add more trains but to make existing services run more smoothly and predictably.
The renovation will address key bottlenecks along the route. With construction underway from July, the project is expected to bring long-term improvements to rail operations. The investment aims to deliver more dependable journeys for both passengers and goods.
