The 301 series (301系?) was an electric multiple unit (EMU) train type introduced in 1966 by Japanese National Railways (JNR), and later operated by East Japan Railway Company (JR East) on Chūō-Sōbu Line and Tōzai Line subway through-running services in Tokyo, Japan, until 2003.
Broadly based on the 103 series commuter EMU, the 301 series was designed specifically for use on through-running services with the Eidan Tōzai Line (present-day Tokyo Metro Tōzai Line) in Tokyo, and was the first aluminium-bodied rolling stock introduced on Japanese National Railways (JNR).
When first delivered, the sets were finished with a clear acrylic paint, giving an unpainted appearance. The sets were subsequently painted in light grey with a yellow bodyside stripe. This was later changed to a light blue ("Blue No. 22") stripe to match the Tōzai Line line colour.
Following reforming into 10-car sets, the fleet was formed as follows, with car 1 at the Nishi-Funabashi end and car 10 at the Mitaka end. Sets K1 and K2 included former KuHa 301 and KuMoHa 300 driving cars with driving cab equipment removed.
|Numbering||KuHa 301||MoHa 301||MoHa 300||MoHa 301||KuMoHa 300||KuHa 301||MoHa 301||MoHa 300||MoHa 301||KuMoHa 300|
Cars 2, 4, 7, and 9 were each equipped with one lozenge-type pantograph.
|Numbering||KuHa 301||MoHa 301||MoHa 300||MoHa 301||MoHa 300||SaHa 301-100||MoHa 301||MoHa 300||MoHa 301||KuMoHa 300|
Cars 2, 4, 7, and 9 were each equipped with one lozenge-type pantograph. SaHa 301-101 was modified from former MoHa 301-4, and retained the original pantograph mounting points.
Seating consisted of longitudinal bench seating throughout. Compared with the 103 series seating, seat width was increased by 50 mm to 550 mm per person.
The 301 series were delivered in 1966 to Mitaka Depot in Tokyo, initially formed as eight 7-car sets. From 1981, the fleet was reformed into 10-car sets with the creation of SaHa 301 trailer cars converted from former MoHa 300 and MoHa 301 motored cars.
A special Sayonara 301 series train was run by JR East on 3 August 2003.
Driving car KuMoHa 300-4 of set K2 is stored at JR East's Omiya Works.
