Usage, optional attributes of a track entry, before endtrack:
uneven <mm> peak deviation of a rail on a 10 m chord, 0-100; normal and switch
unevenup <mm> up and down alone, instead of uneven; normal and switch
unevenside <mm> sideways alone, instead of uneven; normal and switch
unevencross <mm> cross level alone, instead of uneven; normal only
jointdip <mm> depth of the dip at rail joints, every sound distance; normal only,
default 0.4 of the up and down component
Values of uneven follow PLK Id-14 appendix 1: 6 mm is the limit at 160 km/h, 10 at 120,
18 at 80, 35 at 40; half of it for a track in a good state. Example:
uneven 18
unevencross 25
jointdip 6
endtrack
The same fields are in the editor, track panel, section Ride and sound. See
track_uneven_doc.md.
The unevenness is a displacement field over the plan of the scenery, with no random
numbers: one place strays the same every time, and joined tracks, the paths of a switch,
sleepermodel and axles at one place move together. Tracks meet at a joint at the lower of
their values. Joined switches take the lowest of theirs, the tracks joined to them come to
it, and a track with none of a component keeps the switch to its design in it. The clatter
comes from the dipping joints. Curve radius and grade for the physics stay as designed.
Tracks with it get geometry every 2 m on straights: 4x the vertices on Baltyk with all
tracks flagged, 0.2 ms more per frame on td.scn.
