History
Four-car steel-bodied set 1501 in original style in April 1985

The 1500 series fleet was built between 1985 and 1991.[1] The first five four-car sets delivered had steel bodies, while all subsequent sets had aluminium bodies with door pocket windows discontinued.[1] Sets built from 1990 onward used VVVF control.[1]

A programme of life-extension refurbishment commenced in 2002. This involved adding new air-conditioning units, removing the original door pocket windows of the steel bodied cars, and adding front-end skirts.[1]

On 24 September 2012, set 1701 derailed between Oppama Station and Keikyu Taura Station. It was since retired and was replaced by Keikyu N1000 set 1169.

Withdrawal

As part of Keikyu's FY2022 Railway Business Capital Investment Plan, retirements of the first five four-car steeled body sets, numbered 1501 - 1517, commenced in May 2022 with the introduction of new 4-car stainless steel N1000-1890 series sets. [4]

Livery variations

From 25 February 2018, four-car set 1521 was finished in a special "Keikyu 120 years of progress" livery with each of the four cars carrying a different livery used by Keikyu trains in the past. The livery remained on the car until 24 February 2019.[5] Car 1 carries the dark red used on 51 series EMUs from 1924 to 1965, car 2 carries the red and yellow livery used on 500 series and other trains from 1951 to 1963, car 3 carries the red livery used on 1500 series and other trains since 1953, and car 4 carries the red and white livery used on 800, N1000 and 2100 series trains since 1978.[6]
