            }
        }

    ],
    edges: [ // list of all edges

            source: "900000120025", // node id, required
            target: "900000120008", // node id, required
            metadata: {
                lines :["U5","U6"] // list of line ids, required. please note that parallel lines must be modeled as one edge with two metadata.lines entries

            id: 'U6', // line id, required
            color: '#456', // line colour, optional
            group: 'U6' // line group id, optional. lines with the same group id will be merged info one for sections where they run in parallel

Example
