LZB 80: Bremsweg-Simulation mit zugspezifischer Verzögerung - #21
Merged
Conversation
- Refactor LZB centre: movement authority now built from line data and interlocking state rather than telegram payload. Block division falls out of BlockMarker devices. - Add train-specific deceleration to LzbTelegram: derives from brake percentage (BRH), brake apply time (BRA), and speed-dependent falloff above 150 km/h. - Split line conductor payload: LzbSection (cable properties) separate from LzbTelegram (movement authority). Centre regenerates authority each step, so signals stopping ahead shorten it at once. - Introduce BlockMarkerPayload for block boundaries. Block mode (Full/Partial) is no longer a setting—determined by presence of BlockMarker devices in the line. - Move lookahead from ai-driver to sim-core; add block boundary scanning for LZB centre use. - Add lzb_centre integration test: authority ends at occupied blocks, respects block markers, handles signal stops, and tracks train running through the area. - Update Musterbahn demo: add block markers to sections 1 and 2, extend line conductor over edge 1 (full block mode), document the mechanism in MODS.md and README.
