Seibu 6000 Series Train and Tokyu 8050 Series Train at Entrance of Underground Section
The train that shows its roof is a Seibu 6000 series. A Tokyu 5050 series head is visible in the tunnel, but it may be hard to see.
Seibu train started to run on Toyoko Line one month before I took this photo, when Toyoko Line is connected to Tokyo Metro Fuku-toshin Line. Now Tokyu Toyoko Line offers through service to Tokyo Metro Fuku-toshin Line, Seibu Ikebukuro Line, Tobu Tojo Line, and Minatomirai Line of Yokohama-minatomirai Railway. So, we can see trains owned by those railroad companies on Toyoko Line.
