TRACK SEG
Railways
Bridges, culverts and track structures spread across thousands of route miles, many over a century old.
Structure record / single pane of glass
Every record behind every structure, ready on day one.
Structures engineers lose days digging through decades of scanned drawings and inspection reports before real engineering starts. Gephyra links every legacy record to the exact asset it describes.

Method
From archive to answer, traceable at every step.
IN-01
Ingest the archive
Drawings, inspection reports, repair histories. Any scan quality.
RD-02
Read the record
Drawings, title blocks, tables and handwritten notes read at archive scale.
RG-03
Register to the asset
Matched to the right bridge element, track segment or milepost, and the right date, even when structure numbers and names changed over decades.
DL-04
Deliver it inside the job
The full history of the structure in front of the engineer on day one, with links back to every source page.
Input / Reality capture
Drone imagery and LiDAR give the current geometry that every legacy record is registered against.

Title
Single pane of glass
One view per structure, for the work you already do.
Drawings, inspections, repairs, ratings and drone captures, resolved to the same element and the same timeline. Open the structure, not twelve folders.
01
Load rating
Original sections, repairs and documented section loss for each member, in one place.
02
Rehab scoping
Every past repair, retrofit and drawing revision for the element you are about to touch.
03
Inspection prep
Prior findings pinned to the element, next to the latest drone capture.
04
Capital planning
A consistent history per structure across the whole inventory.

Why now / physical AI
Reading is solved. Linking is not.
Multimodal AI can finally read engineering drawings, title blocks and handwritten notes at archive scale. The hard part is linking each record to the right asset in space and time. That is a registration and data-fusion problem, and it is what we are built on.
Drone and LiDAR captures give a current geometric baseline. Legacy records are registered against it, so a 1962 drawing and a 2024 scan point at the same pier.

General notes
Built to work alongside your engineers.
NOTE 1.
Verification
Every answer links to its source page. Engineers check the record, not the software.
NOTE 2.
Fits existing work
Starts on a job you already have. No new platform rollout.
NOTE 3.
Your data stays yours
Security and data sovereignty suited to public owners.
