Colorado Railway Map — Mainline, Regional and Freight Rail Network

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

Colorado rail network drawn from data mapped by OpenStreetMap contributors, 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.

Colorado has 8,575 mapped railway segments including 10 tram lines, 795 light rail segments and 78 narrow gauge segments..
