Classification of railway accidents

Ludwig von Stockert (1913) proposed a classification of accidents by their effects (consequences); e.g. -on-collisions, rear-end collisions, derailments. Schneider and Mase (1968) proposed an additional classification by causes; e.g. driver's errors, signalmen's errors, mechanical faults. Similar categorisations had been made by implication in previous books e.g. Rolt (1956), but Stockert's and Schneider/Mase's are more systematic and complete. With minor changes, they represent best knowledge.

• Collisions

  Collisions with trains:

  • Head-on collision
  • Rear-end collision
  • Slanting collision

  • Collisions with buffer stops (overrunning end of track)
  • Collisions with obstructions on the track (may also cause derailment)

  • Collision with landslips (incuttings)

• Derailments

  By location:

  • Plain track
  • Curves
  • Junctions

Other

• Fires, explosions and release of hazardous chemicals (including sabotage/terrorism)
• People falling from trains, collisions with people on tracks

• Passing signals at danger
• Excessive speed
• Mishandling of the engine (e.g. boiler explosions)
• Failure to check brakes and safety systems as well as sand reserve
• Failure to stop at required positions, e.g. level crossings with defective equipment or shunting movements that lead to occupied tracks.

• Allowing two trains into same occupied block section
• Incorrect operation of signals, pointsortoken equipment

• Poor design
• Poor maintenance
• Undetected damage
• Overloading or freight that is not adequately secured.
• Fire starting from combustion motors, electric cables or equipment, leaking fuel or cooling oil

• Track (permanent way) faults
• Bridge and tunnel collapses
• Poor track or junction layout

• Other railway personnel (shunters, porters, maintenance personnel, etc.)
• Non-railway personnel
• Accidental
  • Accidental track obstruction e.g. with road vehicles or by working construction vehicles
• Deliberate (vandalism, terrorism, suicide, extortion, sabotage)
  • Deliberate track obstruction, e.g. with road vehicles or (heavy) objects
  • Intentional damage to infrastructure like tracks, points or signals
  • Level crossing misuse
  • Trespassing
  • Attack
  • Riot

• Track obstruction or damage by landslides, avalanches, floods, trees
• Fog or snow that obscure signals or the current position of the train
• Wet leaves (or their remains) making the tracks slippery.

• Strength of rolling stock
• Fire hazardsordangerous goods in the train, in involved road vehicles or the vicinity
• Effectiveness of brakes
• Inadequate rules
