The Lyon trolleybus system (French: Réseau de trolleybus de Lyon) is still part of the public transport network of the city and commune of Lyon, France. Opened in 1935, it combines with the Lyon Metro, the Lyon tramway network and Lyon's urban motorbus network to form an integrated all-four scheme.
Lyon was one of the first cities in France to experience trolleybuses. It is the capitale du trolleybus français ("capital of the French trolleybus"). In 1961, the Lyon trolleybus system had the largest number of trolleybuses ever to operate simultaneously in France (370 vehicles). In the 21st century, it has been a leader in the development of new trolley buses.
The system is owned by SYTRAL, and, like most of the rest of the all-four scheme, is operated by Keolis Lyon on behalf of Transports en commun lyonnais (TCL). Since 2006, it has been expanded by the electrification of two major new lines (C1 and C2). As of 2015, the system consisted of nine lines.
Currently located at the main Museum Site, Lyon 1704 is in need of considerable attention.
