Buenos Aires railway usage map. Passenger main lines, branch lines, freight-only rail corridors, heritage railways and industrial tracks — filterable by type.
Buenos Aires railway network classified by operational usage type. Main lines carry primary intercity and regional passenger services. Branch lines are secondary routes with lower frequency and speed. Freight-only lines serve industrial areas, ports and logistics hubs with no scheduled passenger service. Heritage and tourist railways operate preserved rolling stock, usually seasonally. Industrial railways connect factories, mines and yards to the main network. Filtering by usage type shows how extensive the freight-only rail network is compared to the passenger network, or where heritage railways cluster geographically.
