'This report describes Guidelines on Modelling a Train by use of Graph. The proposed model considers Services, which are requested by the Customers, as Vertices and concrete solutions, which delivers the requested Services, are represented as Edges.
The model is added information concerning Component properties at the Edges and information concerning Conditions and Constraints at the Vertices.
The Model describes the most important connections between Components and Subsystems in a Graph, which can be processed by an Algorithm.'
