Double-decker trains arrive on the Metz-Luxembourg line as France and the Grand Duchy chase 21,000 peak-hour seats

The Grand Est Region unveiled at Metz station on 4 May 2026 the first of 16 double-decker trains now running on the Metz-Thionville-Luxembourg line. Each five-car Z26500 set seats 554 passengers, up from 313, and has been cleared to cross into Luxembourg since 29 April. The plan lifts peak-hour capacity toward 21,000 seats by 2030, with Luxembourg co-funding a new Metz-area workshop.
