Scharfe Kritik an Bahn wegen Baustelle auf Ausweichstrecke

Lower Saxony’s regional transport authority has sharply criticized Deutsche Bahn over short-notice construction work that is expected to add pressure to an already complicated replacement service in the Hannover region.

The Landesnahverkehrsgesellschaft Niedersachsen, or LNVG, says the planned closure of a S-Bahn track near Ehlershausen will affect three S-Bahn lines between Hannover and Celle and make substitute services more difficult to operate.

LNVG managing director Carmen Schwabl said the information came too late and that the agency was not informed in time while the replacement service was being planned. According to the reporting, the railway initially did not respond to the criticism.

Additional work on an already strained corridor

The dispute comes during the ongoing major shutdown on the Hamburg-Hannover corridor, where construction began on May 1 and is scheduled to run until July 10. That work has already required a large-scale bus replacement service.

According to the report, that substitute operation is broadly functioning reliably so far, with up to 31 buses in service and only limited passenger complaints.

That makes the extra track closure near Ehlershausen especially sensitive. The Hannover-Celle route is an important feeder and diversion corridor in the region, so any additional disruption can complicate timetables, transfers and connections beyond the immediate work site.

The planned Ehlershausen closure is now set for June 22 through July 5, overlapping almost fully with the wider Hamburg-Hannover works.

Why LNVG is objecting

LNVG’s main criticism is not only that the work will cause more disruption, but that it appears to have been announced too late to be properly built into the replacement concept. Schwabl said the agency was not included in the planning in time.

That matters because the authority is responsible for helping organize rail replacement services in the region. If a diversion route is reduced or interrupted without enough warning, the substitute network can become less effective even when the main line closure was already anticipated.

The report says the affected S-Bahn lines run between Hannover and Celle. For passengers, that means the disruption does not stay confined to one isolated stretch; it can ripple through daily commuting patterns across the region.

The criticism also lands at a time when the wider replacement service is already under pressure from the Hamburg-Hannover closure. The additional work on the alternative route risks making the overall travel picture less predictable for people who depend on the corridor.

Broader stakes for passengers and planners

For passengers, the immediate risk is additional delays, longer journeys and more complicated transfers between buses and trains. Even if the main replacement service continues to operate, extra construction on a fallback route can reduce resilience in the system.

For planners, the case raises a familiar question: how closely must large rail works be coordinated when one project depends on another route staying available? In this case, the criticism suggests the answer was not close enough.

The issue also has a wider political and operational dimension. Niedersachsen is already preparing for more major corridor projects in the coming years, including further large-scale work in 2027 and 2029. That makes the current dispute a test of how well diversion routes and substitute services are coordinated before future shutdowns.

The current reporting suggests the replacement buses on the Hamburg-Hannover line have so far avoided a major wave of complaints. But if an alternative route is also affected, that balance can change quickly.

What happens next

The most immediate open question is whether Deutsche Bahn or its infrastructure unit, DB InfraGO, will publicly explain the Ehlershausen work and its timing.

It is also unclear whether the plan will still be adjusted before the closure begins on June 22. If the timing or scope changes, that could ease pressure on the Hannover-Celle replacement concept.

For now, the case highlights the practical cost of short-notice rail works: not only on the line being closed, but on the routes meant to absorb the disruption. That is why the LNVG criticism has landed so sharply.

Passengers in the Hannover, Celle, Lüneburg and Uelzen area will be watching for further changes in the coming days as the closure date approaches.
