"Railway" objects are of linear type. Railway parameters make it possible to deploy railways in lines. A railway line is configured in two parts:
•Its geometry.
•Its acoustic parameters (from the software's database, see railways list).
A railway line is made up of its platform upon which ballast is laid and upon which the different tracks are then laid.

Ballast contains a porous type "C" material that cannot be edited. It is possible to customize the material of the railway platform.  |
