Lusa questioned Porto Metro after the report by the National Monitoring Committee of the Recovery and Resilience Plan (CNA-PRR) released on Wednesday indicated that "the delivery of the rolling stock is expected in April 2025, although there is an expectation that the deadline could be brought forward".

"This is the contractual deadline, and as the report itself indicates, we are working with the supplier consortium to bring forward the delivery of some units to the fourth quarter of this year", in a "phased" delivery of vehicles, a source from Metro do Porto responded to questions from Lusa.

The PRR report also states that "the circulation of the first vehicles, not yet powered by hydrogen, is expected during the month of August, in a testing phase".

"The lack of rolling stock, as of now, does not make the operation unfeasible, which can be carried out using traditional vehicles", the report reads.

In the case of rolling stock and the energy production system, "the approval has already been granted by the Court of Auditors after the successful bidder has paid the fees", also states the document from the PRR Monitoring Committee.
