Proven 3-in-1 convertible seating enables one carriage to serve daytime, lounge and overnight markets - helping operators make better use of rolling stock and bringing back the fun of family travel Berlin, Germany - October 09, 2026 - As part of its strategy to decarbonise transport and achieve a 90% reduction in transport emissions by 2050, the European Union is seeking to shift more long-distance journeys towards sustainable transport modes, with rail playing a central role.

For operators, however, the challenge is making long-distance and night-train services commercially viable while delivering an experience that brings passengers back.

At InnoTrans 2026, Butterfly Flexible Seating Solutions (Butterfly Seating) officially launched the latest version of Butterfly-Rail, a convertible sleeper-seat solution designed to address a fundamental challenge of night-train operations: the limited utilisation of dedicated sleeper accommodation.
