Railways

The sound source „Railway“ is radiating to all sides unless the option „Self-Screening“ is not activated (see Common Input Data, Self-Screening).

The railway object may have different heights at each polygon point (see Object’s Geometry). The source is located at the top edge of the rail (railhead) with a relative height of 0.6 m by default.

Radiation from sound source „Railway“, relative height 10.6 m, option „Self-Screening“ deactivated	Radiation from sound source „Railway“, relative height 10.6 m, option „Self-Screening“ activated, additional width L/R 2 m each

The command Parallel Object (see manual „Introduction to CadnaA“) on the context menu of a railway enables to generate barriers, embankments, or contour lines at a specified distance or to generate station marks into the direction of the road using the command Generate Station (see manual „Introduction to CadnaA“).

The parameters of a railway are entered in edit mode on the dialog Railway that opens when double-clicking on the railway’s center line.

Note

The subsequent chapters are specific for each standard or guideline available in CadnaA. These specifications do not represent a copy of the standardized procedures, rather the way they are implemented.
