The deal signed on June 22 will see Hyundai Rotem provide ongoing maintenance and repairs for CPTM's CAP 320 EMU cars over the next four years. The trains are used on Sao Paul’s lines 9, 11 and 12.

Hyundai Rotem will use its next-generation Maintenance Management Information System (MMIS) to handle maintenance processes across three different lines and depot locations.
