This is the sixth episode of a railway related to Chuo-ku.
This time, I would like to take a look at some of them.
As an overseas access base in Chuo-ku, Hakozaki's [Tokyo City Air Terminal] (nicknamed T-CAT) comes to mind, but in this series, "Railway" is the leading role, so I will look at it from that point of view.
The aviation administration of Japan opened [New Tokyo International Airport] (Narita Airport) as a base for overseas air routes in 1978 (Showa 53) with the aim of separating Japan and overseas. A lot of people move between central Tokyo and Narita, each of those who go abroad and enter Japan.
Among the railways running in the city, Narita Express and Airport Rapid run on the JR Sobu Express Line (underground), and Narita Access Limited Express runs on the Toei Asakusa Line. Both are convenient access routes that allow you to reach overseas counters without transfer from the city center.
By the way, did you know that there was a plan called "Narita Shinkansen" in the past?
Construction was started in 1974 (Showa 49) with the aim of opening the port before Narita opened, but it was abandoned due to opposition from residents along the railway line, and after the construction was frozen, the Japanese National Railways was privatized, and finally abandoned on the way. It is a "maboroshi high-speed railway".
Using the station site and track site acquired at that time, the [Keiyo Line] was opened on the central Tokyo side, and on the Chiba side, it was diverted to [Narita Access Route]. 
It means that the current Keiyo Line and Tokyo Station were originally prepared for Shinkansen.
If the Shinkansen was built as it was, it would have been running almost the same route as the current Keiyo Line around Hatchobori from the basement of Kajibashi Street. If you imagine a Shinkansen train running at high speed near the basement of [Sakuragawa Park] beside Hatchobori Station, it feels a little strange.
Time passes, Haneda Airport has re-internationalized, and the above-mentioned Toei Asakusa Line is also useful as an access to this sky. The value is increasing as a direct connection route between Narita and Haneda. In order to further speed up, there is also a plan to short-circuit around Asakusa and Sengakuji on separate tracks.
The longing for the sky is growing more and more. From Chuo-ku to Chuo-ku, passing through Chuo-ku, new dreams abroad spread. I wanted to go somewhere again.
