Map |
The map of the railway system in this training module has two principal tasks.
On the one hand it is an extension of the time distance diagram concerning the
arrangement of the stations. On the other hand it is used for the visualisation of
the specified timetables.
Sometimes the arrangement of the stations in a time distance diagram is
insufficient for a right
interpretation of the specified timetables. Some Information about the interconnections of the stations
are missing. A time distance diagram gives so information about the existance and the type of a connection
between two station. A connection could be single-tracked or double-tracked.
Without this information you can not decide the meaning of an intersection of two timetable
curves. Will the
two trains collide or not? This missing information is given by the map which contains the
railway system.
The map shows the set of the specified stations of the corresponding diagram.
A station in the map is illustrated by a
station icon and they are interconnected by rails (see Figure 17).
The rails could be single-tracked or
double-tracked (one rail per direction).
Figure 17
The following subsections explain the creation and editing of a map. You will see how to move stations and interconnect them via rails.
