By the end of this guide, you will know which R4 stretches are most affected, what the reduced frequency means for your trip, and when it is worth choosing another route. It is for daily commuters, students, and anyone relying on Rodalies for work or appointments in Catalonia.
What is happening on the R4?
Passengers on the R4 Rodalies line in Barcelona are facing delays of more than 30 minutes after two infrastructure incidents, according to Renfe. The problems are between Sant Sadurní and La Granada, and at Montcada Bifurcació. Renfe says technicians are working to fix the faults as soon as possible.
The immediate effect is not just slower journeys, but fewer trains. Between Martorell and Terrassa, there are only two trains an hour in each direction. Between Martorell and Vilafranca del Penedès, the service is down to one train an hour in each direction.
Who feels the disruption most?
The R4 is one of Catalonia’s main commuter lines, linking Manresa, Terrassa, Sabadell, Barcelona and Vilafranca del Penedès. That makes the disruption especially awkward for people who cannot easily shift their schedule, including office workers, students, and anyone connecting to other Rodalies or regional services.
If you are travelling from the Penedès or Vallès areas, the reduced frequency matters as much as the delay itself. A missed train can mean a much longer wait than usual, which is why the line is more disruptive than a simple late-running service.
What should you do before you leave?
Check live updates before setting off, and allow extra time if you need to cross Barcelona or make a connection. If your trip is time-sensitive, such as an exam, medical appointment, or work shift, it may be safer to look for an alternative route or travel earlier than planned.

Quick takeaways
Best for: commuters and students who need the latest R4 status before travelling.
Avoid if: you have a fixed arrival time and no room for delay.
Key point: the problem is not only the 30-minute-plus delays, but the reduced train frequency on key stretches of the line.
Renfe has not given an estimate for when normal service will resume. Until then, the safest approach is to check again just before departure, because Rodalies disruption can change quickly and the timetable you saw earlier may no longer be accurate.
