Direct train operation between multiple railways is a convenient transportation system. A good example is seen in the southwestern part of the Tokyo metropolitan area, where three companies form an extensive railway network. They are Tokyu, Tobu and Tokyo Metro. As a result of establishing this network, we can see various kinds of trains on these lines. Specifically, taking subway train pictures on the surface tracks during the daytime is a great amusement for rail fans. I am going to show you two examples today.
The top photo is the EMU Tokyo Metro 08 series traveling near Miyamaedaira Station on the Tokyu Denentoshi Line. The 08 series was launched in 2003 in preparation for direct operation between Tokyo Metro Hanzomon and the Tobu Isesaki lines. A total of 6 sets, 60 units, have been manufactured by Nippon Sharyo. The octagonal black face with a purple stripe is a good accent of this train. For your information, purple is the line color of the Tokyo Metro Hanzomon Line.
The following photo is the EMU Tokyo Metro 8000 series shot at Aobadai Station on the Tokyu Denentoshi Line. The 8000 series was launched in 1981. A total of 19 sets, 190 units, have been manufactured by Tokyu Sharyo, Nippon Sharyo, Kawasaki Heavy Industries and Knki Sharyo over 14 years. Its design was inherited from the 6000 series on the Chiyoda Line.
Direct train operation network... it is a "train museum" for rail fans in the Tokyo metropolitan area.
