1. Overview
Connections (Connessioni) are the logical “glue” that links commercial Services to physical Traces. They define the network topology, including specific paths, transit times, and critical operational handovers (Ready/HO times) between stakeholders.2. Technical Field Mapping
Testata (Connection Header)
Defines the high-level routing and service association.| Field | Source | HTML Name | Description |
|---|---|---|---|
| Servizio | js-servizi | id_servizio | Associated commercial service. |
| Origine / Dest. | js-nodes | luogo_partenza/arrivo | Fixed endpoints for the connection. |
| Via | js-nodes | luogo_via | Mandatory transit node (optional). |
| Spot | Static | spot | Flag for non-regular ad-hoc services. |
Relazioni (Segments & Handovers)
Connections define a rigorous timeline for intermodal handovers. All fields are Time inputs.| Handover Type | HTML Name | Description |
|---|---|---|
| Booking Cut Off | relazione_booking_cutoff | Deadline for order entry. |
| MAD IF | relazione_..._mad_shunting_railway_company | Ready for Railway Co. |
| HLR IF | relazione_..._hlr_railway_company | Handed over to Railway Co. |
| MAD Terminal | relazione_..._mad_shunting_terminal | Ready for Terminal handling. |
Connection Segment Interface
The interface below illustrates the technical configuration of a Railway Relation, including handover timelines, rolling stock (Muta Carri), and commitment parties.
3. Operational Handover Logic
A Connection is the technical blueprint that ensures commercial promises (Services) are technically feasible.I. The Handover Timeline (MAD/HLR)
The system enforces a rigorous timeline for intermodal responsibility:- MAD (Messa a Disposizione): The timestamp when the cargo is physically ready at the terminal for the railway company.
- HLR (Handed Over): The timestamp when legal and physical custody is transferred to the Carrier.
- Logic: These times are used in the Execution module to generate the “Ready-to-Load” alerts for terminal operators.
II. Rolling Stock Integration
Connections link specific Rolling Stock Models (Mute Carri) to a route. When a trip is generated from this connection, the system automatically pre-populates the Rail Planning “Tetris” view with these specific technical wagons, reducing manual effort for planners.4. Connectivity Matrix & Propagation
Inbound Dependencies
- Services Module: Links the route to a commercial offering (e.g., “Bavaria Express”).
- Traces Module: Links the logical connection to physical train numbers and Infrastructure Manager (IM) paths.
Outbound Impact
- Trip Generator: This is the primary input for the batch generation tool. Without a valid Connection, no operational
Viaggio(Trip) can be instantiated. - SLA Monitoring: The MAD/HLR baseline defined here is compared against live timestamps in the Admin & Reports module to calculate carrier performance KPIs (Service Level Agreements).
