History

The first 3700 series sets were introduced in 1991, replacing the original 3000 series trains.^[1] The first six-car sets were delivered in 2000.^[1] Sets from the 6th batch onward (set 3828 onward) had restyled front ends with the headlights located near the roof. Two eight-car sets (3808 and 3748) were leased to the Hokuso Railway becoming Hokuso 7300 series sets 7808 and 7818, supplementing the two 7300 series sets owned by the Hokuso Railway.^[5]

In 2017, eight-car set 3738 was converted and renumbered to become Chiba New Town Railway 9800 series set 9808, owned by the Chiba New Town Railway and operated by the Hokuso Railway.^[6]

Eight-car set 3778 was transferred to the Hokuso Railway, becoming 7300 series set 7828. The transferred set began revenue service with the Hokuso Railway on 26 February 2018.^[7]

In December 2021, eight-car set 3768 was leased to the Hokuso Railway and became 7300 series set 7838.^[4] In addition, 7300 series set 7818 was returned to Keisei; it regained its original set number (3748) and was shortened to a six-car formation.^[3]
