Millions of French commuters suffered a second day of travel chaos on Wednesday as striking rail workers locked horns with President Emmanuel Macron's government in a dispute over reforming the state-owned SNCF railways.

Commuters in and around Paris pushed their way onto the few trains running during the rush-hour while many platforms in the French capital's busiest stations lay empty.

SNCF said the number of drivers on strike fell slightly on Wednesday, though more signalmen and conductors had walked out than a day earlier. Across the company, including administrative and sales staff, the participation rate dipped.
