In 2023, Metro de Madrid had 24,206 incidents that involved delays, of which almost 90% were caused by a lack of drivers. The number of drivers has fallen from the peak of 2,078 in 2012 to 1,1 last year, according to data managed by the unions.

Meanwhile, the number of travelers has grown by 10%, but almost 10% fewer drivers are working. The announcement has generated uncertainty among a staff of 1,891 train drivers, who say they have seen for years how the person responsible for this transport system skimps on personal resources.
