The Secretary of State for Mobility acknowledged in parliament that rail constraints between Lisbon and Setúbal are due to a lack of trains, caused by decades of underinvestment. Cristina Pinto Dias stated that the government is seeking compatible rolling stock, likely from Spain, to address the shortage, as purchasing new trains would take up to a decade. Opposition parties criticized the government for operational chaos and overcrowding, while the government maintained that safety standards are being met and ruled out an immediate takeover by the national rail operator, CP, due to existing concession contracts.
