Abstract

An integrated system is described for the design of horizontal, vertical and super elevation alignments, taking into account constraints while maintaining all consistency requirements. Proposed solutions for appropriate management and analysis will be presented and evaluated on the basis of real implementations and experience. Due to the global approach, and the consistency checks, an efficient tool is made available for the best fitting alignment, and generation of railway control maps necessary for the maintenance and alignment of the construction machines. The system has been used successfully by both the Swiss (SBB) and German Railways (DB). Due to the general approach adopted, an extension was possible with respect to the design of switches, a task which can now also be solved efficiently. 1 Introduct
