Every layer is relative to a centreline. This centreline does not have to
be a part of the layer. In the previous example, layer one - general fill
- uses the centreline for calculation even though the centreline is not
part of the layer surface. Whereas the centreline is part of layer three
- final surface.
Horizontal and vertical alignments
All rail jobs must consist of at least one horizontal alignment. Each horizontal
alignment can either be typed in manually using the
Alignment editor
app, or
converted from a rail design package using
Import data
from the job menu or
the Design To Field component within the Infinity.
Horizontal alignments can consist of straights, circular curves, clothoide, para-
bolic curves and bloss curves.
Vertical alignments can consist of straights, circular curves and parabolic
curves.
If a design comprises multiple tracks, one horizontal alignment can be defined
as the chainage centreline. From the chainage centreline, all chainages are cal-
culated and horizontal and vertical alignments can be used to define each
track.
Rail definition
Define rails by:
•
Entering the design data manually in the field
•
Using the
Alignment editor
to define the centreline only
•
Using
Import data
from the job
•
Converting data from a rail design package using the Design To Field com-
ponent and if necessary the Rail Editor (for defining the superelevation)
component within the Infinity program
Rails are stored as continuous 2D or 3D lines within the rail job.
Tracks
Tracks are used to group related centreline and rails together.
For single tracks, the track centreline and the two rails are grouped in one
track.
For multiple tracks where one chainage centreline is used for all tracks, each
track consists of four lines: the track centreline, the chainage centreline and
the left and right rails.
For multiple tracks where chainage is calculated relative to the track centreline,
each track is stored as a single track as described previously.
Horizontal and vertical alignments
All tunnel jobs must consist of at least a horizontal and a vertical alignment.
These data can be converted from a road design package using the Design To
Field component within Infinity.
