Overview
- The incident began when an empty convoy suffered an 'enganchón' between its pantograph and the catenary on the Redondela–Vigo Guixar stretch, which left the line without electrical tension.
- Loss of line tension prevented electric traction and forced Renfe to reassign rolling stock for the 08:00 service from Vigo.
- The replacement train then had a separate technical fault, causing the service to depart Vigo about 55 minutes late and to reach A Coruña around 10:40 with roughly a 1 hour 10 minute delay.
- Adif technical teams repaired the catenary and reported that traffic was restored by about 11:00, ending the immediate interruption to the Atlantic corridor.
- Passengers affected went to customer-service points to file complaints and request refunds under Renfe punctuality rules, and the episode highlights how non‑passenger movements can trigger wider disruptions to regional services.
