French rail unions have called for a day of protests over pensions as French President Nicolas Sarkozy tries to overhaul public sector pension privileges.
The rail unions have called the strike on 18 October in a bid to defend their right to retire at 50.
French labour unions have warned the strikes could last longer than a day if the President refuses to listen.
Three other transport unions are still debating whether to join the strikes, according to French media reports.
