Deutsche Bahn denies sudden RE1 line construction surge amid political scrutiny

German rail operator Deutsche Bahn has denied any unusual surge in last-minute construction work on the RE1 regional train line between Frankfurt (Oder) and Berlin. According to a government response to a parliamentary inquiry by the Left Party (Die Linke), the statement is based on information provided by Deutsche Bahn.

The company's infrastructure subsidiary, DB InfraGO, has restructured its construction planning in recent years. Going forward, maintenance and investment projects will be managed separately under what the company calls "maintenance containers" and "investment containers." The former cover routine, short-term work—typically overnight single-track closures every four to eight weeks for minor repairs.

Major construction projects and comprehensive infrastructure upgrades, meanwhile, are grouped into investment containers. These result in longer closures lasting between one and six months, followed by multi-year periods without significant disruptions.

The federal government states that such measures are generally planned years in advance. The goal is to consolidate construction phases and subsequently provide passengers and infrastructure operators with extended periods of uninterrupted service.
