One car was designated as a "women-only car" during the morning and evening peak periods on weekdays as a measure to reduce sexual assault during crowded times.[3]

History

The first trains entered service on 1 July 1980.[4] These were the first air-conditioned trains to be used on the Higashiyama Line.[5] A total of 23 sets were built between 1980 and 1990.[6]

Withdrawal and resale

The last remaining 5000 series train in service, set 5114, was withdrawn from the Higashiyama Line following a special final run on 30 August 2015.[7]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