It is not necessary to draw routes or links always as straight lines. If desired for display<br />

purposes these lines can also contain corners. Such corners are only used for clearer<br />

visualization of the diagram, they do not have any impact to the operation of trains.<br />

Guidelines for routes and links:<br />

• Routes and links must touch the blocks at the correct entries/exits, because this affects<br />

the direction of travel through the related blocks assumed by the Dispatcher.<br />

• Routes are to be used, if the track connection between both blocks contains turnouts<br />

or crossing.<br />

• Each pair of blocks can be connected by at most one link, but by an arbitrary number<br />

of routes.<br />

13.2 Nodes<br />

Imagine the following block diagram, that shows two yards with 4 blocks each. Each<br />

block in the left yard is directly connected with each block in the right yard by a route.<br />

There are no blocks between both yards.<br />

Diagram 132: Multiple Routes without Nodes<br />

The structure of this small diagram does not look very clear at all. The routes can be<br />

formed and overlaid, though, to show a more clear structure as shown in the following<br />

image.
