How To Read
This page gives an overview of all the pages in the Wiki and gives guidelines on where to read through depending on your purposes. Being an interdisciplinary model RTM is used by both IT developers and railway people. More about this is given on the “Quick start” page [1] and its subpages [2], [3].
RailTopoModel® is a UML model used for describing how to represent topology of the railway network. The development of RTM began with the list of use cases [4].
Special feature of RTM lies in a way to model aggregation of different levels of details (railway line, node (Mutterbahnhof in Germany) or station). Formal model of RTM is based on connexity graph [5]. railML® 3 implements these methods in XSD schema [6].
Overview of RTM methods and UML model is given on the Modelling concepts page [7] and the Core Elements page [8] correspondingly. Structure page [9] reviews basic requirements of RTM i.e. being able to model topology [10] and aggregation of railway network [11]. More about levels can be found on the Levels of detail page [12].
Placing topology into the world, e.g. relating topology with a set of coordinates is explained on the Positioning page [13] and its subpages [14], [15], [16], [17]. As nodes in RailTopoModel® may have length each of point of the range (length) may be placed in the real world by the method of intrinsic positioning [14]. Concept of linear positioning [15] is explained and specialized as positioning on railway line (via mileage) [17].
Placing railway infrastructure on the top of topology is described on the page of positioning objects [18].
During the development of RTM, possible further works were determined, which are described on the Model Extensions page [19].
See models used to describe railway infrastructure from other perspectives on the Borders of RTM page [20].
