On 25 January 2018, a commuter train operated by Trenord derailed in Pioltello when two of its carriages came off the track en route to Milan. The incident left three women dead and more than 100 people injured, of whom 46 needed medical assistance in hospital. Five of them were in critical condition.[2]
Train operator Trenord said that the train was travelling at normal speed when the derailment occurred. Witnesses said that the train experienced vibrations for a few minutes before the accident.[4]
Investigation
Italian police began an investigation into the accident and said that a problem with a track switch could have caused the derailment.[5] A broken rail on a section of jointed track 2.3 kilometres (1.4 mi) from the crash site was later identified as the cause of the derailment. That section of track was scheduled for replacement.[6]
