A central issue for operators of suburban passenger train transport systems is
providing sufficient number of seats for the passengers while at the same time
minimising operating costs. The process of providing this is called rolling stock
planning. This technical report documents the terminology, the processes, the cost
structures and the requirements for rolling stock planning at DSB S-tog, the suburban
passenger train operator of the City of Copenhagen. The focus of the technical
report is directed at practical train operator oriented issues. The technical report is
thought to serve as a basis for investigating better methods to perform the rolling
stock planning (to be the topic of later papers). This technical report is produced as
a part of the current industrial Ph. D. project to improve the rolling stock planning
process of DSB S-tog.
