The 2006 Rome Metro crash occurred on 17 October 2006 at 9:37am local time (07:37 UTC), when one train ploughed into another train as it unloaded passengers at the Piazza Vittorio Emanuele II (or Vittorio Emanuele) underground station in the city centre, killing a 30-year-old Italian woman, named Alessandra Lisi, and injuring about 145 others, of which a dozen were reported to be in life-threatening conditions.
While no official cause of the accident has been released, officials have excluded terrorism as a cause for the incident. Several passengers have reported that the driver of the moving train failed to stop at a red signal and that the train had been running strangely at previous stations. A senior driver has disclosed that the moving train had previously had braking problems on a test drive.
A possible explanation of the accident may lie in a misunderstanding between the driver and the control centre, which would have authorized the train to proceed to the "next station", meaning a station closed to the public (Manzoni), the last before Vittorio Emanuele station, while the driver would have understood it to mean the next working station, that is, Vittorio Emanuele itself.
