Paris, April 4 (RHC) -- Millions of French commuters were affected on Wednesday as train traffic has been heavily disrupted during the second day of the rolling strikes staged by French rail workers against a planned reform of the state-run SNCF railway operator.

The company said only one in seven of the high-speed trains would run and half of scheduled regional trains would be affected by the movement on Wednesday.

On Monday evening, the country's unions started a series of month-rolling nationwide rail strikes with a wave of two successive days out of every five days.

They planned 36 days of action for April-June period, a move that may paralyze the eurozone's second economic power and one of the world's top tourism destinations.

They are pressuring President Emmanuel Macron to reconsider plans to scrap preferential terms of rail workers, including retirement on full pension at 52, a decade earlier than other French employees.
