The 3500 series sets operate on the Keisei Main Line.[2] The eight-car sets were also used on Toei Asakusa Line and Keikyu line inter-running services until they were split into individual four-car sets in 2014, although the unrefurbished sets were not capable of operating on Keikyu lines.[2]
Originally built as 24 four-car sets, the fleet was subsequently reformed into eight-, six-, and four-car sets.[2]
As of 1 April 2016[update], the fleet consists of 56 vehicles formed as four six-car sets and nine four-car sets.[1]
The six-car sets are formed as shown below. All cars are motored.[1]

Major refurbishment of the fleet commenced in 1996, with a total of 56 vehicles refurbished by 2001.[2] Refurbishment involved redesigned front ends with square lights instead of round and upgraded interiors.[4]
Special farewell tours were staged for the last remaining unrefurbished 3500 series set, 3585, on 25 and 26 February 2017.[5]
