• Renfe’s substitute plan readies 58 buses and 43,500 daily seats, including Fabra i Puig–Vic direct services every 15 minutes, Fabra i Puig–La Garriga hourly, and staged trips to Centelles every 30 minutes.
• Renfe has been running empty test trips, publishing exact bus timetables, deploying 90 staff at transfer hubs, and keeping a nine‑bus reserve along the C‑17 to shore up frequencies.
• Mayors from affected towns warn the road alternative may fall short at peak times and press for reliable coordination, while Catalonia splits the La Garriga–Montornès corridor into two lines and opens a Vallromanes–Montmeló route at 30‑minute intervals.
