Accidents and ATP



Accidents preventable by ATP



  • Canada Russell Hill Subway Crash - 1995 - Driver passed two signals at danger, resulting in a collision between two subway trains. The line was equipped with train stops, but they were installed incorrectly and thus did not function.


  • Australia Hines Hill train collision - 1996 - driver misjudges end of crossing loop during simultaneous cross with opposing train. Two killed.[citation needed]


  • United Kingdom Watford rail crash - 1996 - Signal passed at danger resulting in collision with coaching stock. One killed.


  • United Kingdom Southall rail crash - 1997 - Signal passed at danger, resulting in a collision between a passenger train and a freight train crossing the track in front of it.


  • United Kingdom Ladbroke Grove rail crash - 1999


  • Australia Glenbrook train disaster - 1999 - too fast after Stop and Proceed.[citation needed]


  • Belgium Pécrot rail crash - 2001 - Train departed a station passing by a red (closed) signal. 8 killed, 12 injured.

  • Australia Waterfall train disaster - 2003 - too fast around very sharp curve after driver suffered a heart attack.


  • United States 17 September 2005 - Too fast through turnouts between Joliet and Chicago.[3]


  • Japan Amagasaki rail crash - 2005 - Overspeed through sharp curve. 107 killed, 555 injured.[4]

  • Bulgaria 12 July 2014, Kaloyanovets - Overspeed through turnouts set to diverging track. Driver dead, 14 injured. ATC (EBICAB) was available but wasn't turned on.[8][9]


Accidents not preventable by ATP



  • United Kingdom Clapham Junction rail crash - 1988 - wrong-side failure - both signal and balise would have shown false green lights. 35 killed, 100 plus injured.[citation needed]


  • Australia Cowan rail crash - 1990 - wrong-side failure - caused by sand on the rails.[citation needed]


  • Singapore Clementi train collision - 1993 - oil spillage on track, may have interfered with normal ATP operation on the 12 trains that arrived at Clementi MRT Station in the early morning since the oil have come into contact with the ATP power system fixed into the rails. The ATP system in question is continuous ATP, which is still used on the North South MRT Line and the East West MRT Line. 156 injuries, no deaths.[citation needed]


  • Germany Bruehl train disaster - 2000 - too fast through turnout during single-line working and degraded operations.[citation needed]
