According to Lisbon Metropolitan, on these two weekends in November, Campo Grande and Quinta das Conchas stations will be closed, meaning circulation on the Yellow line will be interrupted between Cidade Universitária and Lumiar stations, until 1pm.

From 6:30 am to 1:00 pm, circulation on the Yellow line will be in sections, between Lumiar/Odivelas/Lumiar and Cidade Universitária/Rato/Cidade Universitária. The Campo Grande station on the Green Line will be operating normally.

The service will be normalised from 1pm, at which time the entire Yellow line will begin running.
