History

The 3700 series was introduced when Narita Airport Terminal 1 and 2, 3 stations were opened. There are eight and six-carriage units, and the eight-car units are used on through-services towards Toei Asakusa and Keikyu lines as well as Hokuso Railway. The six-car units were also used on the through-services to Asakusa Line until 2014.

Hokuso Railway also introduced the same trains called 7300 series. In addition, Keisei has been leasing three eight-car units to Hokuso Railway (which are now called 7800 series) and another eight-car unit to Chiba New Town Railway (which is now called 9800 series). The 7300 and 7800 series are effectively the same in these days.

Those introduced in 2000-02 have a different front end, which looks like 3000 series.


Current Operations & Future Prospects

The 3700 series are still widely used for Keisei Main and Oshiage Lines including the through-services. They are used on Narita Sky Access Line as Access Express when there is a lack of available train, but it is extremely rare in these days. Those leased to Hokuso Railway and Chiba New Town Railway are mainly used on through-services on Keikyu, Toei Asakusa, Keisei and Hokuso Lines.
