ÖBB completes double-tracking of the Marchegg Ostbahn

The roughly 37 km Marchegg Ostbahn line between Vienna-Stadlau and the state border at Marchegg has been under double-tracking and electrification since 2015, including replacing level crossings with over-/underpasses, noise barriers, and barrier-free rebuilding of nine stations. A partial section (Wien-Stadlau–Marchegg, selective double-track incl. electrification) was already completed by ÖBB in December 2022; full double-tracking was scheduled for completion by end of 2025. The source does not state a specific investment figure. Update (11 Oct 2025): Since 11 October 2025, electrically hauled trains have again run through between Vienna and Bratislava on the Marchegger Ostbahn; the line had been closed since 4 March 2024. With the Slovak section up to Bratislava now finished, the gap is closed; on the 37 km Austrian section, double-tracking, electrification, step-free stations and the replacement of all level crossings in Lower Austria by underpasses are complete. The Rex8 takes 56 minutes from Wien Hbf to Bratislava hl. st. at up to 160 km/h; there are 38 regional services a day (19 each way), and four Eurocity pairs are added at the timetable change on 14 December 2025 (46 services in total).
