South Dakota Railway Map — Mainline, Regional and Freight Rail Network

South Dakota interactive railway map. Mainline, regional and freight rail network — filterable by speed, electrification, track gauge and line usage.

South Dakota rail network drawn from OpenStreetMap data, covering mainline railways, regional lines, commuter rail and freight corridors. Lines are colour-coded by rail type and filterable by maximum permitted speed, electrification system, track gauge and line usage. The map reveals the layered structure of the network: high-speed intercity spines, slower regional connectors, freight-only branches serving ports and industrial zones, and heritage lines preserved for tourism. Switch between filter modes to view the same railway infrastructure through a different lens — the same line that appears as a passenger main line in usage mode will show its permitted speed and electrification system in the other views.
