Import an infra from railjson

BufferStops are obstacles designed to prevent trains from sliding off dead ends.

Detector is a device that identifies the presence of a train in a TVD section (Track Vacancy Detection section), indicating when a track area is occupied.

To allow electric trains to run on our infrastructure, we need to specify which parts of the infrastructure is electrified.

These define the types of switches available for route management.

LevelCrossing is an intersections where a railway line crosses a road

NeutralSections are designated areas of rail infrastructure where train drivers are instructed to cut the power supply to the train, primarily for safety reasons.

Operational point is also known in French as "Point Remarquable" (PR). One OperationalPoint is a collection of points (OperationalPointParts) of interest.

A Route is an itinerary in the infrastructure. A train path is a sequence of routes. Routes are used to reserve section of path with the interlocking.

Signals are devices that visually convey information to train drivers about whether it is safe to proceed, stop, or slow down, based on the interlocking system and the specific signaling rules in place.

The SpeedSections represent speed limits (in meters per second) that are applied on some parts of the tracks. One SpeedSection can span on several track sections, and do not necessarily cover the whole track sections. Speed sections can overlap.

Switches allow for route control and redirection of trains.

`TrackSection`` is a segment of rail between switches that serves as a bidirectional path for trains, and can be defined as the longest possible stretch of track within a rail infrastructure.
