新宿の回送線です。野良犬、壊れた屋台、トルコの看板などいかにも新宿の裏側って感じですね。この回送線Google Mapで調べると今は遊歩道になってるようですね。
There was a dedicated deadhead line behind the Shinjuku main streets. A masterless dog, broken food cart, signs of sex-related shops etc. made up an atmosphere of the back of downtown Shinjyuku.

この場所を同定しようと、この前日本に行ったとき見に行ったんですが、えらく変わっていて同定不可能でした。

I wanted to determine above location and visited the place the line used to be when I was in Tokyo for business trip. However the place had changed so much and it was impossible for me to determine the place.
