The track mode Kilometrage (X, under More) puts a point of the km where a track is clicked: the line, the km and, at a jump,
the km on from it. The axis of a line follows the main paths of the switches through the tracks of its points; on a
double-track line it runs between the tracks, and where they part on formations of their own and come together again it
runs along the longer one, the shorter one going by its own length with its last hectometre before they meet taking up
the difference (PKP GK-1 6.1.12). The km between the points are stretched to the length of the scenery evenly; the panel
lists the points with the stretch, the 3D view shows the axis, a tick at each hectometre, the points with their km and
the km of the lines by the mouse. Read the km from the posts turns the hectometre posts along the line into the points
of its km, a jump where two runs of numbers meet, and warns of a jump on a curve or at a station (Id-1 § 19). Each change
is a step of undo.
The station keeps its km and the direction of its numbering in its record. The block signals are named after their km, odd on track 1 and even on track 2, the sections after the signals at their ends, and each signal gets the control of its section.
Bridged stretches less than 5 m apart are merged into one bridge on its piers, and those shorter than 3 m, a ditch or a
culvert under the embankment, are no bridge. A bridge end within 1 m of a joint of the route or a break of the line moves to
it, so the cut leaves no sliver of a path by the abutment. Against the OpenStreetMap railway bridges the marked share stays
the same (lk91 60 of 66, TG 90 of 104); the places with nothing under them in the map fall from 6 to 4 on lk91 and from 18
to 12 on TG, and the bridge paths shorter than 1 m from 9 to 0 and from 11 to 1.
Where the terrain model falls away under a fitted line by the abutments, the paths are cut off at the ends of the stretch as the line is applied and set to the bridge, in the same step of the history: they sound as on a bridge, get no formation and the terrain under them stays as the model has it, also after the scenery is saved and opened again. Tunnels and tracks set to the bridge already are left as they are. The status says how many paths went on a bridge.
A switch may lie on a concave vertical curve, and on a convex one no sharper than 2000 m (Dz.U. 2026 poz. 1225 § 58 ust. 16): the fit bends over the switches and their shared timbers where the ground does, a curve on a switch is a warning, and only a sharper convex one an error. A sharp crest of a hump keeps its curve off the switch zones. The zone of a crossing reaches only as far as the path crossed has rails, so the middle of a double slip keeps to itself.
A line runs through a switch along its main path, and through the quarters of a double slip straight on, so the long lines go through the slips and the connections between them are fitted after. Rails of the lines fitted already nearer than a sleeper is long are taken at their height, as both lie on the same timbers. A short line between two lines whose end grades can't be joined within the norms keeps only the heights of its ends, and the grade breaks at the joints. The norms speed of a line is the one most of its length is laid for, so a few tracks set much faster don't stiffen the curves of all of it.
The fault finder leaves out the places over the terrain model on a bridge or a viaduct, the ground falling away under them by the abutments. A formation modifier may be open at its start or end.
Laid to the norms, the readout says the design speed of the transition curves and of the cant: that of the track the laying goes on from or joins, or the one set for the laying. A new option takes the set speed also on from a track with its own, the new tracks get it; Ctrl+Shift+wheel steps it while laying and turns the option on. The panel shows the speed the laying under way is designed for.
A track laid on from a free end in the PKP PLK laying, by a drag out of the end, by clicks from it or laid back onto it, starts from the curvature and the cant the end has. An arc turning the same way as the end is a compound curve: a transition of the norms ramps the curvature and the cant from the one arc into the other. From a straight the arc gets its entry transition, the arc then straight its exit one. Where the way is too short the transitions are cut and the cant lowered to what they ramp, and the readout says so; with no room at all the track is laid as before and the note says why. The curves traced on the orthophoto and the recommended values of a compound curve get the transitions between their arcs too. The free laying stays as it was.
The free laying isn't the default any more. The first time a session opens the laying or the plan, a window asks how the
new tracks are laid, with the two cards of the panels (the norms marked as chosen); a click on one of them takes it and
closes the window, which comes before the offer of the terrain model of a new scenery. "Remember the choice, don't ask
again" keeps it in eu07_editor.ini (track_norms ask, free or plk), and a choice kept follows a later click on the cards of
the panels; the settings of the editor (General) choose between asking and either way. The self-test scripts start with the
free laying, as they were written for it.
M in any tab of the track mode turns the tape on: a click puts its start, the next one its end, at a free end, on the axis
of the track under the cursor or else on the ground. The readout at the cursor gives the distance in plan and in space,
the difference of height and the grade between them and the azimuth, while the second point follows the cursor and once
it's put; a further click starts a new measure, M or Esc puts the tape away. Self-test command tape.
In the top view at a metre a pixel or closer, each curved track of 5 m or more gets "R 600 L 120" by its middle and each
switch its name and its type from the kept switch record ("Rz 60E1-300-1:9 P") by its start, on a dark plate as on a plan.
A label which would cover another one is left out, the switches going first and then the sharper curves. View > Track labels
in the top view switches them off.
View > Track colours draws the rail tracks over the view in bands of the radius of their paths, of their speed or of the grade
along them, from above over the whole view and in the 3D view within 1.5 km of the camera, with the legend of the bands in
the bottom right corner. Plain keeps the lines of the top view as they were. Self-test command trackcolours.
After a change of the tracks, once the mouse is let go, the joints check looks at the joints of the tracks changed and of
the tracks they join, with the limits of the Joints panel: ends almost meeting, steps, kinks, jumps of the cant and of the
grade get a marker with the value in the view while the panel is closed, and go away once a later change or an undo puts
them right. The check of a track is shared with the panel (joints_check takes the list and the pairs seen), the pairs
already looked at are kept by the tool instead of a global. Self-test command jointslive.
The frog, movable nose and 3D sleeper and timber fields of the track properties and the frog chips of the switch panel stay
in place while track_features::crossings or track_features::sleepers are off, greyed, with a tooltip saying the feature is
switched off in this build; nothing changes them, copying and pasting the properties leaves them out.
Each end of a rail track joined to nothing, where a train would run off, gets a red dot next to the white dots of the joints,
in the 3D view near the camera and from above over the whole view. The ends are looked for again after an edit or once the
camera leaves the place they were found for, not every frame.
After the cursor rests on a track, its label gives the grade at the place pointed at and the cant of the path, besides the
name, the length, the radius and the speed; a curve whose radius isn't written in the scenery gets the one of its geometry
instead of being called straight.
Next to the length and the radius, the readout at the cursor shows the difference of height from the start to the end of the
track about to be laid, the grade along it (one value or the range it goes over) and the speed the sharpest arc lets the
trains through at within the cant and the unbalanced acceleration of the laying limits. The self-test layclicks logs it.
The points of a grade line read from the tracks keep the radius measured there; once a point between them was taken out, the
breaks of its neighbours changed while their radii stayed, so a break without a curve read as 0.4 per mille became one of
9 per mille with no curve, and the tracks took it as a kink. The neighbours of the point taken out follow the limits now,
with the button, Del and the self-test alike (profile_remove_point).
Applying a line with a break without a curve gave the path which ends at the break the grade of the element after it, so
its Hermite heights bowed 0.12 m off the line over 100 m before the break; each path takes the grade on its own side now.
Self-test commands vprofilerun, vprofiledel and vprofileput.
In place of a line bent every ten metres to keep within 0.1 m of every bump,
the grades and the vertical curves are fitted to the ground the way the
profile fits them. Where the formation is made in the terrain model the line
keeps to the radius of the norms and cuts and fills; over the ground left as
it is it bends as sharply as it has to. The joints keep the height and the
grade of the track joined, no grade is capped and no piece is under 5 m.
