The 22:40 northbound stops at Dunmore for ninety seconds. CCTV shows a woman boarding carriage six with a single hard-shell suitcase, taking a window seat, and settling in for the run. The next station is forty minutes up the line with no scheduled stop between.
When the conductor came through, the suitcase was still on the rack. The seat beneath it was empty. The doors had not opened. That contradiction is the whole of the case, and three years on it has not given an inch.
Full reporting in progress. Replace with the timetable analysis, CCTV review, and sourced interviews.
