DB SEV GmbH

DB SEV GmbH is a limited liability company (GmbH) within the Deutsche Bahn group, headquartered in Berlin. It was founded on 27 June 2019 and is jointly held by Deutsche Bahn AG and DB Regio AG. Its core mandate is to plan, organise and manage rail replacement services (Schienenersatzverkehr) — the buses that carry passengers when rail lines are closed for construction, maintenance or disruption. The company centralises rail replacement transport for the group. It draws on a network of roughly 3,800 bus operators that can be contracted to provide the actual driving services. This pooling approach allows Deutsche Bahn to procure replacement capacity at scale rather than leaving each regional unit to arrange buses independently. A landmark assignment came with the 2024 general renovation (Generalsanierung) of the Mannheim–Frankfurt am Main line, known as the Riedbahn. For the first time, Deutsche Bahn awarded the replacement transport directly to DB SEV GmbH, which required around 150 buses. Vehicles deployed included buses equipped with luggage compartments and toilets, reflecting the longer-distance nature of the replacement operation. Since 1 November 2022 the company has also been active in France, extending its rail replacement management beyond Germany. As a wholly group-owned service entity, DB SEV GmbH is not separately listed and operates as part of Deutsche Bahn's passenger transport ecosystem, closely tied to DB Regio.

DB SEV GmbH was founded on 27 June 2019 as a limited liability company within the Deutsche Bahn group. Its shareholders are Deutsche Bahn AG and DB Regio AG. The company was created to take on the planning, organisation and execution of rail replacement services (Schienenersatzverkehr), centralising a function that had previously been handled in a more fragmented way across the group. Its main field of activity is the planning, organisation and implementation of rail replacement transport. By bundling these services centrally, DB SEV GmbH can call on a network of around 3,800 bus operators to carry out the actual journeys. This gives Deutsche Bahn a single point of coordination for replacement capacity when rail lines are unavailable. On 1 November 2022 the company expanded its footprint beyond Germany and began operating in France. A significant milestone came in 2024 with the general renovation (Generalsanierung) of the Mannheim–Frankfurt am Main railway line, known as the Riedbahn. For the first time, Deutsche Bahn awarded the replacement transport directly to DB SEV GmbH. Around 150 buses were needed for this operation. The vehicles used included buses with luggage compartments and toilets, suited to the demands of the replacement service on this important corridor.
