The nominal visual acceleration and braking rate used between calling-point boundaries. A compressed journey may use a higher derived rate when that is required to retain its arrival time. |
Increasing it makes the train reach cruising speed sooner and brake later, which can look abrupt. Reducing it produces gentler, longer acceleration and braking but may make short legs feel sluggish. Arrival timing does not change. |

The explicitly synthetic equipment ceiling used only when LINX does not supply a usable vehicle maximum speed. |
Increasing it permits a missing-LINX service to move faster on known high-speed track. Reducing it can make that service look slow. The value remains synthetic evidence, not a vehicle fact. |

The explicitly synthetic infrastructure limit used only over route distance for which OSM supplies no usable line speed. |
Increasing it can make untagged sidings look too fast; reducing it can make untagged main lines look too slow. Unknown distance remains measurable in every shaped profile. |

This strict upper bound decides whether an intermediate arrival is close enough to schedule for GRM to infer the following departure from elapsed timetable time. |
Increasing it allows timetable-derived departure for later arrivals, improving continuity when direct departure evidence is missing but increasing inference risk. Reducing it makes GRM wait for direct TD or TRUST departure evidence more often. Zero disables this timetable-derived departure path. |

After a directly observed intermediate arrival, this delay is added to the scheduled departure before GRM may infer that the service has departed. |
Increasing it keeps a service at the platform for longer but may make a genuinely departed train appear late to start moving. Reducing it makes movement begin sooner but increases the risk of showing a train as departed while it is still at the platform. |

This allowance is added after the latest relevant scheduled or direct operational instant before GRM closes a service whose normal terminal evidence never arrived. |
Increasing it keeps incompletely tracked services live for longer and delays an incorrect closure, but also retains stale services. Reducing it clears stale services sooner but can terminate a severely delayed or sparsely reported service too early. The 24-hour maximum matches the shaped TRUST evidence horizon. |
