Île-de-France Railway Electrification Map — AC, DC Voltages and Non-Electrified Lines

Île-de-France railway electrification map. AC and DC systems by voltage — 15kV, 25kV, 3kV, 1.5kV — alongside non-electrified and diesel rail lines. Filterable by system.

Île-de-France railway electrification status and system type for every line. AC 25kV 50Hz is used on most modern high-speed and intercity lines; AC 15kV 16.7Hz dominates in Germany, Austria and Switzerland; DC 3kV is common in Italy, Poland, Belgium and Spain; DC 1.5kV is used in France, the Netherlands and parts of Asia; DC 750V third-rail is typical for urban rapid transit. Non-electrified diesel lines are shown separately. The electrification map is essential for understanding cross-border train compatibility, identifying electrification upgrades in progress and planning multi-system rolling stock operations.
