The switch panel and the track properties show the frog and movable nose boxes only with track_features::crossings, and the
sleeper and timber model fields of the pack only with track_features::sleepers.
- sleepers3d / sleepers3dplain / sleepers3dbed in eu07.ini: timbers put together from the begin, main and end parts of a model
and stretched to their length, plain sleepers of their own model; tracks whose plain sleepers would touch are laid as one
cluster, lines of timbers led by priority and turned to the bisectors of frogs and crossings at a limited rate, whole timbers
under crossings, split ones between tracks with room to part them, gaps filled per rail and overlaps shortened or dropped;
clusters worked out in a background thread while driving, on demand in the editor
- the ballast can be left out under the beams (sleepers3dbed no)
- blades get their heel and throw from the switch template or blades <heel> <throw> in the scenery; blades of double switches
run on into the track linking them to the next switch
- rail cutting at frogs, wing rails, movable noses and switch crossings done by one carving pass (RailCarve)
- tint of the rail treads applied to the colour only, without the matte band at the frog
- a switch trailed through with a movable nose set the other way derails the vehicle
- self-tests: sleepercheck, sharedzones, beamsnear, throw, sleepersbg
