Overview
- A staged stoppage by the Metro workers’ union cut the number of trains in service, pushing waits past 30 minutes on several lines.
- Line 4 service was halted on the Canal del Norte–Santa Anita stretch after arcing on the tracks caused a short circuit.
- RTP buses and some police patrols moved riders during the Line 4 shutdown to keep trips going on the affected corridor.
- A short circuit at Salto del Agua on Line 1 triggered a flash with smoke that led crews to remove a train, with three passengers treated for anxiety.
- Metro officials said affected trains were withdrawn for workshop review as technical investigations proceed to determine precise causes and reinforce safety.
