Could a similar crash occur on SE Queensland's rail network?
The answer is yes, but at lower speed as most of SE Queensland's rail network is below approx. 100kph speed limit. SE Queensland's rail network is riddled with very sharp bends with low speed limits - for example 14% of the Ferny Grove Line has speed limits of 60kph or lower due to sharp curves. The narrow gauge of Queensland's railways does not help, as trains are less stable on curves compared to wider track gauges. There is still no ATP on SE Queensland's rail network (parts of Sunshine Coast Line excepted) to enforce speed limits around these sharp bends. Thus driving to the speed limit is entirely down to train driver judgement. Whilst Queensland Rail and it's drivers have a very good safety record, it only takes one driver's inattention to kill dozens of passengers. The continuing lack of ATP (due to delays in implementing ERTMS - Level 2 signalling) on Brisbane's rail network is an accident waiting to happen.
