The 9000 Series cars were the second group of cars to be purchased from Breda. In addition to all the same features that 7000 Series cars have, these cars have enhanced access for disabled passengers and warning lights to alert passengers that the train doors are closing. These cars can be found on Line 7 and the Tres Olivos-Hospital Infanta Sofía section of Line 10. The next batch to be delivered will operate on Line 6, replacing the 5000 Series cars which are the oldest in the system.
