Withdrawal and resale
See also: Buenos Aires Underground rolling stock

The last remaining 5000 series train in service, set 5114, was withdrawn from the Higashiyama Line following a special final run on 30 August 2015.[7]

In 2015, five 5000 series units (30 vehicles) were shipped to Argentina to be used on Line C of the Buenos Aires Underground. These sets were modified with pantographs to operate from a 1,500 V overhead supply instead of the original 600 V third rail.[8]
