In July 2023, the Scarborough RT met its unexpected end with a derailment south of Ellesmere Station. The underlying cause was a loose segment of reaction rail struck by the train. The last car separated from the train and the rear truck lifted completely off of the tracks. A major issue raised by the investigation was poor track inspection and maintenance procedures, possibly influenced by a combination of badly trained junior staff and the assumption that the line would close soon and did not require much ongoing work.
