Claim 0:
1. A method for waypoint-based rail navigation comprising:
determining a waypoint-based command comprising a set of instructions associated with traversal to a destination, the destination comprising a GPS location of a predetermined feature of a rail network selected, at a user interface, from an aerial image overlay of the rail network;
determining an updated track geometry version comprising a version identifier and a set of nodes and edges, each node indexed in association with a GPS location, each edge extending between a pair of nodes;
storing the updated track geometry version at a memory onboard the rail vehicle;
at a centralized motion planner, commanding the rail vehicle in track-geometry-referenced coordinates, comprising:
transforming the destination into a track-geometry-referenced position comprising a linearized distance along an indexed track edge of the track geometry; and

autonomously controlling the rail vehicle based on the track-geometry-referenced coordinates, comprising:
at the rail vehicle, validating that the track-geometry-referenced coordinates are associated with the version identifier of the updated track geometry version; and
controlling the vehicle on based on the track-geometry-referenced position.
