# Rail Wagon Registry (Carri)

> Detailed management of rail wagons and technical safety compatibility.

The **Carri** module is a critical safety component of the rail logistics chain, managing the physical assets and their technical constraints.

## Registry Management

* **Wagon Registry**: Individual wagon data, including UIC numbers and ownership details.
* **Wagon Types**: Classification based on length, number of axles, and loading deck height.

## Compatibility Matrix

This is a central logic hub connecting **UTI Types** to **Wagon Types**.

* **Assignment Rules**: Defines exactly which containers can be placed on which wagons.
* **Geometry Checks**: Prevents unsafe loading based on overhang or weight distribution.

## Maintenance & Archive

* **Revision Dates**: Automatic alerts when a wagon is reaching its technical maintenance deadline.
* **Cestino**: Management of archived or decommissioned rolling stock.
