A night train concept named ALISA was presented at InnoTrans 2026 in Berlin, developer and supplier interests confirmed at the show.

The concept targets the European sleeper market, where several operators have added or expanded overnight services in recent years following renewed passenger demand and political support for rail alternatives to short-haul flights.

Details released at the presentation remain limited. The exhibiting party showed the ALISA concept as a proposed vehicle and interior configuration for overnight trains rather than a confirmed production order, so any fleet application depends on an operator committing to procurement.

Trade visitors at InnoTrans 2026, held in Berlin, viewed the concept among a wider programme of rolling stock presentations covering daytime and overnight passenger products.

Night train procurement in Europe has recently involved consortia and individual operators ordering new sleeper stock, with delivery timelines extending to the end of the decade. Whether ALISA enters that pipeline will become clear once an operator announces a contract; until then, the concept stands as a design proposal seeking a customer at the sector's largest trade fair.
