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.^{[citation needed]}

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]
