The prototype set, S1, was delivered in May 1992, and entered revenue service on 19 September 1992.

On 8 August 1992, set 8001 achieved a speed of 160 km/h in a special test run.

The subsequent fleet of full-production sets entered service from 18 March 1993.

The entire fleet underwent life-extension refurbishment between 2004 and 2006. Beginning in 2023, the fleet underwent another programme of refurbishment. The sets will receive a new livery based on that of the newer 8600 series, as well as wheelchair spaces, power outlets, reupholstered seats, updated traction equipment, and Western-style toilets. In addition, smoking compartments were removed. Treated "S" sets are planned to enter revenue service from 23 December 2023, and treated "L" sets are planned to enter revenue service from August 2024. The entire fleet is planned to be refurbished by 2027.
