 During rehabilitation of these cars in 1993, an exterior loudspeaker was added in place of where one of the rollsigns used to be.The cars also received General Electric AC propulsion (same as that of the AnsaldoBreda A650 railcar used on LA Metro), replacing the original Westinghouse cam control DC propulsion systems, making them the first cars on the system to use such propulsion systems.The 1000-series cars were the only ones to have more seating capacity than the other cars, with 82 seats.
