This is the eighth installment in my “Photographing Subway Trains” series. You're getting quite familiar with it by now, aren't you? Today, I'm featuring the Shinjuku Line. The theme is “A Subway Line That Crosses Rivers.” But before getting down to the main topic, let me give you the usual introduction.
・What’s the Shinjuku Line?
The Shinjuku Line is Tokyo’s ninth-oldest subway line. It opened in 1978 and is operated by the Tokyo Metropolitan Bureau of Transportation (Toei). The line is 23.5 km long, connecting Shinjuku and Motoyawata. The 2.5 km section between Higashi-ōjima and Funabori runs above ground. Shinjuku Line trains also run directly onto the Keio Line via Shinjuku Station.
The Shinjuku Line’s route number is 10, and its official line color is leaf green (yellowish green). The line uses a 1,500 V DC overhead power supply. One unusual feature of the Toei Shinjuku Line is its track gauge of 1,372 mm, whereas most railway lines in Japan use either 1,067 mm or 1,435 mm gauge. This unusual gauge is inherited from the existing Keio Line, which the Shinjuku Line connects with.
Toei currently operates 10-300 series EMUs on the line. Meanwhile, Keio’s 5000 and 9000 series EMUs also run directly onto the Shinjuku Line.
・A Train Emerging from a Tunnel
All right, please take a look at the photo above. It shows a Toei 10-300 series EMU emerging from a tunnel near Funabori Station.
Why does a subway train emerge from a tunnel and run above ground here?
The reason is that the line has to cross three rivers in succession in this area: the Kyu-Nakagawa, Arakawa and Nakagawa. As I mentioned in my previous post, building an underground section between Higashi-ōjima and Funabori was expected to be very expensive because of the poor ground conditions. Building an elevated section instead was a more economical option.
Thanks to these challenging construction conditions, railfans can now capture dramatic shots of subway trains emerging from tunnels.
The 10-300 series — so cool!
・A Train Crossing a River
Next, please take a look at the photo below. It shows a 10-300 series train leaving Higashi-ōjima Station and heading towards the Arakawa-Nakagawa Railway Bridge. I used a super-telephoto lens to capture the scene and highlight the bridge’s location in the distance. You can just make out the bridge as a small bump on the horizon.
The 10-300 series — over the river we go!
I thoroughly enjoyed photographing these unique features of the Shinjuku Line!
