The map shows the physical infrastructure named in the contract titles: railway sections between two places as lines and single sites — stations, ports, airports — as points, coloured by spend or by the single-bidder share. Lines are schematic — between the places, not along the route.
Contracts that name no place — train services, rolling stock, fuel — are network-wide and are not on the map. A mode can be picked: railways, ports and the Danube, aviation or road transport.
