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.
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 name of a node or "(no name)" was written out in twenty places and
four local functions, a lower-case copy of a text in four files, the
test for a number, the file name of a template made comparable and the
heading of a direction in three and two, the green main button of a
panel in five and the key=value parameters of a self-test command in
five. Each of them is one helper now: name_of, tall_button_height and
main_button with the panel helpers, numeric with format, normalized
with the include helpers, heading_of with the plan geometry and
selftest_values with the tools; lower gives way to ToLower.
editor_services was growing into one interface every tool depended on
whole. It splits into the roles the editor plays for its tools: the
selection, the view, the undo history, the templates by the track, the
ground with the terrain model, the track design and the guide of the
first steps. Each tool is handed only the roles it uses, so what it
depends on can be read from its constructor; editor_services stays as
the sum of the roles the editor implements.
The third tool out of editor_mode. It reaches the terrain model and the
places of the tracks on it through the services, the place of a track
for the terrain model is a type of its own now, and the laying and the
switches ask the tool for the kink it allows. A self-test command can
ask to be run again in the next frame, as the check against the terrain
model does while the model comes in.
The joints check also compares the tracks with the terrain model (NMT), every 5 m. Bridges, tunnels and tracks over others are left out.
- Each path lying higher or lower than the model by more than the threshold (0.5 m by default) is listed once, at its farthest place off.
- The places are compared with the same offset the model has against the scenery; a scenery not fitted to the model as a whole is measured about its median.
- The squares of the model are loaded in the background, and the check waits for them with a progress bar.
- These entries can't be fixed from the list. In the top view, the overlay shows the issues over the whole screen.
- Self-test: jointsmodel <threshold>.
Labels:
- every button, field, tooltip and message of the editor reread for a beginner: short nouns for the fields with the
sentence in the tooltip, the less used options under More settings, one glossary (field of work, template, track,
grade), sides told from directions, degrees and per mille as signs, messages built from one format string
- plural forms through STR_P; the last entry of a po file is read too, and the Polish plural rule is in the header
- lang/editor_pl.po: the code pass entries merged, 391 entries no code uses and 3 duplicates dropped
- roads: the notes and errors naming a road translated; the build options and the layout fold the texture length,
kerb sizes, traffic share, roundabout part, height over the ground and junction speed limit under More settings, the
lanes start folded
Grade lines fitted to the terrain model (NMT), a line or the whole scenery at once:
- fit_ground: a robust fit on nodes 5 m apart; the ground parting from the line (a bridge, a viaduct, a wall) is gone
past rather than followed, the bends keep off the switches as far as their curves reach, a run of bends the same way
is one point of intersection, a curve with no room is as sharp as the room lets it be
- the ends of the line and the other paths of its switches leading into lines fitted already bound the line by what
the tracks between can climb; ends meeting in the plan, laid apart in height by hand, are joined before the run
- apply_profile: the paths are split where split_path takes the parameter (a straight was cut in the wrong place, into
pieces of a few centimetres the game takes for zero length), no piece shorter than the margin; the paths off the
ends of the route are brought to its height
- Bytom: 1600 lines, grade breaks at the joints 89 -> 20; Tarnowskie Gory: 848 lines, 223 -> 3; no step over 2 cm
