I still enjoy strolling along Tama River. After observing the preserved streetcar on the ex-Kawasaki City tramline, I went upstream another day. My destination was Tamagawa station on the Tokyu-Toyoko and Meguro lines. I walked along the river, and stopped by a shrine named Sengen-jinja, which is located on a hill adjacent to the riverbank.
There was a reason for visiting this shrine. That's because a railway bridge across Tama River can be viewed from the shrine. I could see a bridge of a double-double track. Many kinds of trains constantly crossed the bridge. For example, I saw two kinds of subway trains at one time. They were the EMU Toei 6500 series and the Tokyo Metro 17000 series. The former was directly operated from the Toei-Mita line; meanwhile, the latter was from the Tokyo Metro-Fukutoshin line. The subway trains of two different operators meet each other on the bridge... it's rarely do you ever get to see. I felt this superb view like a reward given by the God of railways. Is that a bit of an exaggeration?
For your information, both the Toei 6500 and Tokyo Metro 17000 series trains debuted in 2021. The former has free Wi-Fi service on the train. That would really help passengers take specifically subway lines. On the other hand, the latter was elected as a winner of the Laurel Prize by the Japan Rail Fan Club last year. It's implemented an advanced train information monitoring and analysis system.
