Restoring the railways starts by seeing them

The public note is at https://x.com/tebayoso/status/2107894676426559739. This is the working version of the project, not a copy of that text.

Enrailar starts as an open project to restore Argentina's railways. Later it can be a railway technology company: research, management, maintenance and operation of infrastructure and rolling stock, inspection robots and drones, autonomous trains, coordination software and renewables on the corridor.

Phase 1 is monitoring. The public launch is February 2027, with the first Hackatrain, an open hackathon for railway technology. The announcement does not name a day: the site shows that reference, and the countdown only when a date is set. The first place we look is Tandil.

The organization is cooperative: technicians, railway workers, municipalities, businesses and users. Budgets, proposals and progress are published with the transparency of a DAO. Operation and safety decisions stay with identifiable professionals who answer for what they sign.

The first step is a living map. Stations, interchanges, yards, track, bridges, tunnels, sidings, level crossings and signaling. Each item with a place, photographs, an inspection date, a condition and an estimate of what it needs in order to work or to improve. Also who runs the section, what gauge it is and what demand it could serve. A historic station is not, by itself, a connection that can be used today.

Part of the survey is civic: people in each city and town, shared protocols and technical review. The other part is automated. Prototype audit robots on the track and drones for the surroundings, with batteries, solar support and a satellite link where mobile coverage does not reach. Those trials start on short runs.

We need to measure track geometry, rail wear, sleepers and fastenings, drainage, vegetation and obstacles. Georeferenced photos, three-dimensional models and heat maps of defects. Ultrasound for internal flaws and ground-penetrating radar for the ballast and the layers under it. Two thousand sensors names the ambition. The prototype starts with the sensors that catch concrete problems and can be checked against a professional inspection.

Worth studying: inspection systems such as ENSCO's, measurement as a service in the manner of Plasser & Theurer, and aerial LiDAR surveying such as DJI Enterprise. The aim is to combine that with engineering, fabrication and maintenance done in Argentina.

Those data rank repairs and estimate what consist a corridor can take. Speed and load also depend on bridges, axle load, braking, signaling and rolling stock. The map has to support decisions that can be checked.

The first commercial product is a railway audit and maintenance tracking as a service, in Argentina and across Latin America. Each intervention is written down: the defect, the work and the capacity that comes back.

While the map grows, commercial operation starts on one corridor. A last-mile operator leaning on the railway: regional depots and stations used as small logistics rooms. The first market is parcels. Trains with modules and lockers, pickup with a code, and local couriers who finish the delivery. Modules that swap so the train does not have to wait on the platform. Quadient and ScotRail are the reference for lockers in stations; the pilot still has to show that moving those parcels by train is worth it.

Corridor scenarios, for study and not as a promise, are stated as tonnage and speed: 10 to 50 tonnes at 30–60 km/h for parcels and parts; 100 to 300 tonnes at 40–70 km/h for pallets and supply; 500 to 1,500 tonnes at 40–80 km/h for containers; 3,000 to 6,000 tonnes at 40–80 km/h for heavy goods where the infrastructure can already carry them. Parcels are the way in.

There is also a regional question: study a trans-Andean connection toward Chile, the historic alignment and the alternatives, grades, tunnels, gauges, weather, customs, demand and financing. That needs its own study and coordination between the two countries.

The start is concrete: a map that can be checked, an inspection prototype and a commercial corridor that works. Publish the results, put them back into maintenance and repeat.
