The is an electric multiple unit (EMU) train type operated by the private railway operator Keikyu on commuter services in the Tokyo area of Japan. First introduced in 1994, a total of eight 8-car sets and six 4-car sets were built by Tokyu Car Corporation and Kawasaki Heavy Industries to replace the ageing 1000 series sets on limited express services.[1]
The 600 series is primarily operated on the Keikyu Main Line. They are also used on inter-running services to the Toei Asakusa Line, Keisei Main Line, Hokuso Line,[2] and the Narita Sky Access Line.[3] Four-car sets are occasionally used on the Keikyu Daishi Line.[4]
, the fleet consists of eight 8-car sets and six 4-car sets (classified 650 series).[5]
The eight-car sets 601 to 607 are formed as follows, with six motored (M) cars and two trailer (T) cars.[5]

The first batch of sets introduced featured transverse seating bays throughout. While most of the seating was fixed,[6] some seats were partially retractable. Later sets featured longitudinal seating. From 2004, the earlier sets were modified with some transverse seating bays replaced by longitudinal seats.
Set 606 received a special "Blue Sky Train" livery in March 2005[7] to commemorate the opening of Haneda Airport Terminal 2.
The 600 series underwent refurbishment from August 2009[8] to March 2014. Modifications included were replacing the wiper cover with a slit of the model number (similar to those found on the 2100 series and N1000 series), narrower front-end skirts, LED side lights, and a pair of LCD information screens above the doorways.[9]
