There are a few locations on Brisbane's rail network where there are dead end terminus platforms - Cleveland, Domestic Airport, the under construction Ferny Grove station, and the planned Kippa-Ring station. Whilst there have been no known recent incidents in Brisbane, dead end termini around the world have a poor safety record. For example the 1975 crash at Moorgate in London killed 43 passengers - this was even with red lights, speed limits, and a dead-mans handle. A dead end terminus accident that injured hundreds allegedly occurred at South Brisbane in 1957. Continuous ATP would prevent the vast majority of causes of dead end termini accidents.
There is also nothing to prevent speeding around the many sharp curves which plague Brisbane's rail network. This was the cause of Brisbane's worst train accident at Camp Mountain crash near Samford in 1947 which killed 16 passengers. Speeding around a sharp corner was the cause of Japan's terrible Amagasaki train crash in 2005 which killed 106 passengers. The Waterfall train accident in NSW in 2003, and Tilt Train accident in 2004 were also caused by trains speeding around a curve too fast. Queensland's narrow "cape gauge" also increases the risk of derailment on sharp curves compared to standard or wide gauge track.
Despite lacking ATP, SE Queensland's rail network has had a very good safety record since electrification. This is likely to be due to QRs high safety standards, culture, and training. Brisbane's infrequent train services and little bit of luck may also be a factor. A recent review by Queensland Department of Main Roads and Transport showed that the most suitable ATP system for SE Queensland would be European Train Control System (ETCS) - Level 2. This is a radio based signalling system with continuous ATP based on widely adopted European standards. The time frame of the implementation of this system is unfortunately unknown to the public. BrizCommuter would like to see installation of ATP to be an election issue. The likelihood of being killed or injured whilst travelling by train is a fraction of the risk travelling by car. However, until ATP is installed on Brisbane's commuter railway system, then SE Queensland's dead end termini, sharp bends, and many non-grade separated junctions could be an accident waiting to happen.
