A true microscopic digital twin — physical, logical, and live.
Traditional spatial maps of the rail network lack the logic of the signalling system. Signalling simulators lack real-world telemetry. The MGT bridges this gap by encoding both the physical and logical constraints of the railway into a single graph database — fully aligned with UIC RailTopoModel (IRS 30100) and railML 3.x for seamless compatibility with future ETCS and TMS rollouts.

Key technical innovations
Rather than rely on high-level Train Describer steps alone, the MGT ingests discrete electromechanical and SSI safety-relay transitions — RGPR, HGPR, DGPR, TPR, NKLPR — to build a safety-critical replication of every line-side asset.
Multi-machine crossovers (e.g. ends 710A and 710B) are represented as a single logical switch node. Safety calculations prove both ends have locked in tandem before any path is validated.
Track-circuit edges are appended to a route's lock-set in real time based on live switch position — replicating the active interlocking logic exactly as the signal box executes it.
Fully aligned with UIC RailTopoModel (IRS 30100) and railML 3.x schemas. Designed at the outset for ETCS and TMS integration — not retrofitted.
