At 11:19 p.m., the company stated that the service was back to normal.
Earlier, in a statement released at 11:05 p.m., Lisbon Metro had informed that service on the Red Line was halted due to “an external cause unrelated to the Metro”.
The Lisbon Metro operates daily with four lines: Yellow (Rato-Odivelas), Green (Telheiras-Cais do Sodré), Blue (Reboleira-Santa Apolónia), and Red (Aeroporto-São Sebastião).
Typically, the metro runs from 6:30 a.m. to 1:00 a.m.
