Classification of railway accidents
From Wikipedia, the free encyclopedia
Classification of railway accidents, both in terms of cause and effect, is a valuable aid in studying rail (and other) accidents to help to prevent similar ones occurring in future. Systematic investigation for over 150 years has led to the railways' excellent safety record (compared, for example, with road transport).
Ludwig von Stockert (1913) proposed a classification of accidents by their effects (consequences); e.g. head-on collisions, rear-end collisions, derailments. Schneider and Mase (1971) 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.
[edit] Classification of rail accidents by effects
(Summary only; to be updated, or cross-referenced to full separate article)
Collisions
- Head-on collision
- Rear collision
- Collisions with buffer stops
- Obstructions on the line (road vehicles, landslides, avalanches)
- Plain track
- Curves
- Junctions
Other
- Fires and explosions (including sabotage/terrorism)
- Falls from trains, collisions with people on tracks
[edit] Classification of rail accidents by causes
(Summary only; to be updated, or cross-referenced to full separate article)
Drivers' errors
- Passing signals at danger
- Excessive speed
- Mishandling engine (e.g. boiler explosions)
Signalmen's errors
- Allowing two trains into same occupied block section
- Incorrect operation of signals, points or token equipment
Mechanical failure of rolling stock
- Poor design
- Poor maintenance
Civil engineering failure
Acts of other people
- Other railway personnel (shunters, porters, etc)
- Non-railway personnel
- Accidental
- Deliberate (vandalism, terrorism)
Contributory factors
- Strength of rolling stock
- Fires resulting from accidents
- Effectiveness of brakes
- Poor track or junction layout
- Inadequate rules
