Offsets can be entered in Offset/Check off-
set or Height offset/Check height diff.
The offset is stored as part of the rail job and
recalled whenever required.
Available for Offsets: From library. The
point ID of the stored stake offsets. To select
a different stored offset or to create a point,
highlight this field and open the selectable
list. Refer to "46.3.2 Offset Library".
Available for Stake. Horizontal offset applied
to the position of the reference line as
defined by the design data or as calculated
from manually entered data using the nomi-
nal gauge.
Available for Stake. Vertical offset applied to
the height of the reference line as defined by
the design data or as calculated from man-
ually entered data using the superelevation
and superelevation base.
Available for Check. Horizontal offset applied
to the position of the reference line as
defined by the design data or as calculated
using manually entered data using the nomi-
nal gauge.
Available for Check. Vertical offset applied to
the height of the reference line as defined by
the design data or as calculated from man-
ually entered data using the superelevation
and superelevation base.
This functionality is used in railway tunnels.
The functionality is available for Stake rail
and Check rail.
Some rail projects require extra pendular dis-
placement calculation for the design axis.
The track is rotated based on a line with a
defined height offset (pendulum length) from
the track centreline. This action defines a
horizontal displacement for the track. The
vertical alignment is independent from the
pendular displacement and does not change.
☞
The pendular displacement calcula-
tion only influences the horizontal
position of the design axis. It does
not change the height of the track.
