b'R M U CA ST I STAT Y T A M A S L I A F E I L S RYTRAIN RUNAWAYSAn uncontrolled movement of a train or rolling stock has the potential to result in a serious rail safety event with severe consequences, particularly if it leads to a collision with another train on the running line or occurs in the vicinity of people, thus placing them at risk of being struck. Figure 27 presents the number of runaways over the past five years.There were three runaways of a commercial passenger train reported in 20232024 , of which two were higher risk occurrences. There were seven runaways of a freight train reported in 20232024 , of which five were higher risk occurrences. There was one runaway of a tram reported in 20232024which was not a higher risk occurrence.Since runaways have the potential to contribute to more serious incidents, the ability to identify and respond to a runaway is an important control to mitigating this escalation. Figures 28 and 29 show the consequence events and response actions reported for runaways involving commercial passenger trains and freight trains over the past two years (since the introduction of NRSDS).Figure 30 presents the precursor events or likely causes reported for runaways involving commercial passenger trains and freight trains over the past two years (since the introduction of NRSRS).FIGURE 27: PASSENGER TRAIN (COMMERCIAL)Higher riskOther Rate Runaways, July 2019 to 5 0.05June 2024.4 0.04COUNT OF RUNAWAYS Rate (per million train km)A higher risk occurrence includes a runaway of a train or rolling stock on or3 0.03onto the running line.
