  abstract	= {This literature survey focuses on studies of the train
		  driver system and its connections to other parts of the
		  larger train traffic system. The main part of the studies
		  concern Swedish conditions, but other references are
		  included as well.
		  
		  In the first part, different ways of analysing accidents
		  are discussed, including organisational aspects. In the
		  second part, research results from different areas, all
		  assumed to be relevant to the train driver task, are
		  aggregated into a body of knowledge about the train driver
		  system. Comparisons are made between the train driver task
		  and other operator tasks. Further, the effects of a higher
		  degree of automation are discussed.
		  
		  The task of driving a train is modelled as a dynamic
		  decision task, where the driver's mental representation of
		  the technical system and the optic flow of information are
		  assumed to be important parts of the train driver task.
		  
		  In the last part of the literature survey, the content of
		  40 accident reports is discussed. Further, an analysis and
		  a classification of Swedish train accidents are made by
		  using CREAM (Hollnagel, 1998). The content of the reports,
		  as well as the CREAM-method are evaluated, and different
		  classification criteria are discussed.}
