“Black” day in SNCF transport in Ile-de-France. Unions are calling for a massive strike this Tuesday, May 21 and will significantly slow down traffic on the RER, Transilien and tram in the Paris region.

Difficult to travel on transport in Ile-de-France this Tuesday, May 21. The SNCF has announced a black day on the Ile-de-France networks while the Sud-Rail and CGT-Cheminot unions joined by Unsa-Ferroviaire are calling for a strike. The mobilization is such that for several days the SNCF has been inviting travelers to postpone their trips as much as possible and to favor teleworking this Tuesday. In its detailed forecasts on Sunday evening in a press release, the SNCF confirmed that “the circulation of trains, RER, tram trains, will be very seriously disrupted”.

? The five RER lines are affected by the SNCF strike in Ile-de-France. Very few trains run between 1 train in 5 and 1 train in 2 in the best case.
