Train 7MP5 consisted of four locomotives leading 72 freight platforms and wagons. The total length was 1474m with approximately 2960 tonnes trailing the locomotives. A total of 10 platforms and wagons were derailed, with five obstructing the TransAdelaide track and four coming to rest down an embankment in private residential properties.
