feat(track): vertical unevenness comes near its limit more often, with longer buckles too
...
Fewer short waves: at uneven 18 the humps over 12.6 mm on the 10 m chord
go from 28 to 38 per km, with the peak still at 18 mm. Waves of 47-83 m
join them. They hardly count on that chord, the body rises and falls on
them.
The documentation tells how far unevenness goes before a pantograph
can't keep up. A wire rising fast enough trips the main breaker on a
straight track too: it does at tor0290 on Baltyk, over about 46 km/h.

fix(track): the cross level of an uneven track goes by the place, not by how it was laid
...
Tracks laid towards each other settled to opposite sides: a step of cant
of twice the value at their joint, in the geometry and under the axles.
It's now a tilt of the plan, which reads the same from either track.

...
The phase of the rails was wrapped to the rail length of the track the
vehicle is on, while an axle can be on a track with longer rails. From
then on every frame looked like a joint crossed.

feat(track): track unevenness declared in the track entry
...
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.

feat(editor): a warning of the sudden change of the cant deficiency right behind a switch, as ST-T1-A6 sees it (9.11): a track laid on from the end of the diverging track of a switch, or into it, is checked by switch_curve::check_exit from the end of the curve of the switch, a straight frog's length before its end, to the first sudden change of the curvature of the track laid. Two of them nearer than the intermediate element of table 9.16 (6 m in track connections up to 60 km/h) are taken together, else each one alone, against table 9.15 (130 mm up to 60 km/h), at the speed of the laying or of the diverging track of the switch, the lower one. The view tells of it by the cursor while the track is extended or laid, the status once it's laid; a transition out of the frog straight makes no sudden change. Selftest: from a Rz S42-190-1:7,5 with a frog straight of 1.66 m a curve the other way of R 200 m warned of 194 mm together, the same way none; from a Rz 60E1-190-1:9 with 6.09 m a curve the other way of R 200 m none, of R 120 m warned of 157 mm

feat(editor): a slip is selected, slid and deleted whole: any track of it picked shows all of it selected, editor_mode::slip_of finding its switches by its record, the tracks between them and its four ends. Dragged along, the slip moves along its first track with the straights out to the joints of its template and its crossing track, as far as that one goes on into tracks with their ends free, the straights of its first track before it and past it lengthened and shortened, a metre of them kept; one bent into a curve isn't slid, nor one whose crossing track is joined on beyond it. Deleted, it leaves its two tracks crossing from end to end in its place, kept in the scenery as a crossing Skrz, as a switch leaves its main track; Shift+Del takes all of it, Ctrl+Z brings it back. Selftest: a Rkp laid with its crossing track slid 5 m on and 3 m back, the joints of its template with it, walked through; deleted into a crossing Skrz 1:9 walked through, back with Ctrl+Z; a Rkpd at a crossing of straights with free ends slid 2 m, deleted into a crossing

feat(editor): a slip Rkp or Rkpd bent into a curve of a side track: dragged on a curve with a slip armed it's laid out on the tangent to the curve where it was pressed and bent onto the curve as a switch laid into one is, editor_mode::frame_path laying a path of a template into the curve for both, its crossing track coming along with its ends free, ahead to the side of the drag, the slip curve of a single slip on that side, the straights of both tracks out to the joints of its template. A crossing goes only where two straights cross, a curve as sharp as the slip curves is refused. As it's dragged the view tells the radii of its tracks and slip curves, its cant and what switch_curve::check_slip says, the 11.4 pkt 4b of ST-T1-A6 among it; laid, the status the same. A slip bent into a curve isn't replaced by one laid out of straights. Selftests switchcurve, bladetips: a Rkpd 49E1-190-1:9 in R 800 m with its slip curves of R 154 and 249 m and the warnings of 11.4 pkt 4b and table 9.2, one of R 300 m in R 800 m with no warning of table 9.2, a Rkp in R 4000 m, the blades from 1.248 m on all of them; refused in R 150 m, a Skrz refused

The straights crossing at a skos more than 0.14 deg off it, half of what keeps 1:9.51 and 1:10 apart, are refused with the skos they cross at and the slip of the same kind made for it, of the same rail and radius first, or none; a double slip replaced by one of another skos likewise.

feat(editor): a switch laid with no track there, and no switch laid by a click: a press on the ground with a switch armed lays the switch there, its start where it was pressed, the direction of its main track taken from the drag once it's 4 m long and held, the drag sideways then giving the side of the diverging track, back by the start the direction free again; pressed by a free end within 5 m it goes on from that end in its direction and grade, joined to it. Its ends are left free to lay on from, styled after the track it goes on from or as the lay tool lays its tracks (editor_track::create_switch with a path_style). A press let go within 10 pixels places no switch, a slip at a crossing included, which was laid at once on the press: it's laid once dragged, its straights shown meanwhile. The hints and the panel tell of both. Selftest switchfree: Rz 60E1-300-1:9 on the ground with its four ends free, from the free end of a straight joined and walked through; a click on a straight laid none, a drag laid z1

feat(editor): the norms of a slip switch bent into a curve, as ST-T1-A6 sees it: switch_curve::check_slip tells that a slip is bent in a side track only, never in the running nor the main tracks (11.4 pkt 4b), that a track through it is to keep its curvature of one sign (9.7 pkt 12), that a slip curve bent the way the curve turns gets sharper and no sharper than the 180 m of a side track (table 9.2), and the cant as over a bent switch, with none recommended in a side track (9.3 pkt 5). The cant over a switch is checked by one function for both. Unit tests: a Rkpd of R 190 m bent into R 800 m has its slip curves of R 154 m, below the side track, and 249 m; into R 4000 m of R 181 m, within it; on a straight it's no bent one

They're found now among the tracks with their rails whole too, for the blades of a slip only.

TTrack::join_switches joins the free ends of a switch to the ends of other switches in the same points, on both sides, with the codes of the ends the axles go on by: the end of either path of one at the start of the other, two facing at their starts, two meeting at their ends; done once the plain tracks are joined as the scenery is loaded, the old sceneries too, and as the editor joins a switch laid.

A drive placed, changed or carried along with its switch is set where the blades begin, as they're shaped or where the diverging track is broken at the tip of a planed blade, along the main track there, its heading and its tilt taken there; the drives the earlier versions of the editor set at the joints are moved there once, as the scenery is opened and the templates are known, with no step of the undo history, to be saved with it. Deleting a switch, a double switch or a set of tracks takes the drives of the switches along in the same step, Ctrl+Z brings them back.

The geometry stays as designed, only its reach changes. A design cut down isn't taken whole by the route plan nor merged with a new one nor carried along by a switch slid, and gives no designed curve to the tracks left of a curve it cut, which are recognized as they lie: a track laid by hand into the gap is never pulled back to the old shape.
