The application of many operational research techniques employed by the railway industry requires as input a data model representing the geometrical, structural and operational characteristics of the railway network in question. However, constructing network models with the conventional methods requires a considerable amount of manual work that involves handling large amounts of both qualitative and predominantly, quantitative information. This paper presents an alternative approach for prototyping, constructing and querying railway models, incorporating interactive computer graphics. The presented approach allows the model builder to carry out the modelling task more quickly and accurately. After reviewing the transportation model building trends of the last decades, the authors present the characteristics of the proposed system, demonstrate its main functions and assess its impact on the efficiency of the modelling task.
