maj00r	2c3ab90db5	fix(track): the tip of a blade lying tangent to its stock rail, as in 60E1 and 49E1 switches with cut tips, is where its theoretical arc gets 5 mm off the gauge face of the stock rail less the 125 mm the nose is planed over, instead of where it gets 3 mm off, so the tips lie 1.25, 1.60, 2.11, 2.63 and 3.34 m from the start of the switch at R190, 300, 500, 760 and 1200 as in the tables of these switches instead of 0.2 to 0.65 m nearer it; blades cutting into the stock rail at an angle, as in S42 switches, keep their tips	2026-10-17 23:32:43 +02:00
maj00r	513daa52cc	merge feat/rail-crossings: the split rail code, mitred wide crossings, guard rail treads, check rail spacers and frogs for every rail profile, with the geometric switch blades moved into RailCrossings, their shape in track_rails::switch_blade and the lowering of the head in loft_span	2026-10-17 23:32:43 +02:00
maj00r	306555a654	feat(track): a check rail is held to its running rail by spacer blocks every 0.5 m along its straight part, laid in the same way as the spacers of a guard rail at a wide crossing, below the head from the web of the running rail to the face of the check rail, so the flangeway stays open above them; a check rail replaced by a wing rail gets none; the spacing of spacers and castings is shared by guard rails and check rails	2026-10-17 23:29:08 +02:00
maj00r	7d130be3de	fix(track): at a crossing at a wide angle the floor of the flangeway between a running rail and its guard rail is laid only where real crossings have it, as the cast floor of each corner up to 0.3 m past the rail of the other track and as separate spacer blocks every 0.5 m along the rest of the guard, and the floor takes its texture across its width at the scale of the head instead of one stretched column; the wheels of the other track roll over a guard rail across their whole tread instead of only over the head of their rail; and when the tracks cross at nearly a right angle the treads of the other track are laid as plain spans along the rail instead of lines running almost straight across it, which left fins standing up at every edge of a tread	2026-10-17 23:29:08 +02:00
maj00r	ae4e828ed2	feat(track): at a crossing at a wide angle the tread of the other track is laid where its wheels roll over the mitred corners: the part of a guard rail under the running rail of the other track becomes a running surface in the shared tread material instead of matte, and running rails of different materials share the tread over the rolled band of the other track instead of over a square span; wide_tread draws the edges of the band from the crossing itself, since the gauge lines meet in one point at right angles, and a tread gives its own fade, widened for bands lying across the rail; treaded keeps the matte parts of a guard rail matte, lay_treads splits guard rails at their treads, and a piece of no triangles is not inserted	2026-10-17 23:29:08 +02:00
maj00r	f03c6b8ebc	feat(track): at a crossing at a wide angle every head of one track meets every head of the other in a mitre from the corner of their flangeways to the far corner of the heads, the way the corners of a cast diamond look, so the running rails and guard rails of both tracks form closed corners and only the flangeways stay open, instead of the rails of one track going through and the other ones glued to their sides; corner_cut gives the mitres, as bends of the running rails and as miters of the guard rails; the fit of a loft end to the profile of another rail and the field and gauge outlines of the rail profile are gone with the gluing	2026-10-17 23:29:08 +02:00
maj00r	4016c4ce04	feat(track): the guard rails of a crossing at a wide angle reach a metre past the rails of the other track instead of 0.3 m and open their flangeway over 0.6 m at the ends, the way the guard arms of the corners of a diamond run out on real crossings, the reach and the flare are the constants guard_reach and guard_flare shared by the plan and the layer	2026-10-17 23:29:08 +02:00
maj00r	a88774d279	refactor(track): the rail layout value types (crossings, sizes, check and guard rails, cuts, bands, fills, treads, layout) and the wheel and rail constants live in world/RailLayout.h in track_rails instead of inside TTrack	2026-10-17 23:28:42 +02:00
