PROJECT 02 / 07 · DATA ENGINEERING · INDUSTRY
Structure behind safety.
Translating technical railway specifications into structured data.
Illustrative data pipeline · Not a real railway signalling system
01 / THE CONTEXT
The challenge.
Railway signaling specifications carry complex relationships between messages, packets and variables; the engineering task was to turn them into a consistent, inspectable reference dataset.
02 / MY ROLE
Work with
purpose.
ERTMS Railway Data Analysis & Structuring Intern at JBS Business Services, July–August 2026.
03 / ENGINEERING NOTES
Analyzed public ERTMS/ETCS specifications, with emphasis on Movement Authority Message 3 and relevant packets.
Prepared normalized reference datasets and a structured data dictionary using Python, Pandas, Excel and CSV/JSON.
Drafted 10 prototype validation rules and technical documentation for early-stage V&V support.
04 / HIGH-LEVEL SYSTEM
From idea to structure.
Public-facing conceptual overview — not a disclosure of internal implementation.
05 / THE STACK
The tools
behind the work.
06 / MOTION STUDY
See the concept.
Fifteen seconds along a fictional railway: a position reference, a radio exchange, a structured Movement Authority, and a train that stays within its limit. An original illustration of public ETCS Level 2 concepts.
POSITION / 0–3 SEC
A reference along the railway.
The train passes a fictional Eurobalise. Onboard ETCS uses the balise group as a positioning reference, together with onboard odometry.
Original educational illustration. Positions and timing are fictional. No operational data, braking model or certified safety simulation. Trackside signals are context only; the radio authority comes from the RBC.
Simplified public ERTMS/ETCS concepts, fictional railway positions, and illustrative movement only. Not a real signalling or braking-system simulation.
07 / TRAINING RECORD
Learning the language of rail.
