History
The 3400 series trains entered service in 1993, and were built using the underframes and control equipment from the original AE series Skyliner Limited Express EMUs and steel bodies based on the (stainless steel bodied) 3700 series EMUs. Construction continued until 1995.

Withdrawal
Following the introduction of new 3100 series EMUs for use on Narita Sky Access Line services, Keisei began relegating its 3050 series fleet to mainline operations, thus resulting in the 3400 series fleet being withdrawn from 2020. one 3400 series set remains in operation.
