We went to Tamagawa.Sta to take pictures of the train.
Since many rail fans seem to know the detailed diagram, more than 6 people were taking pictures of the same train from the same point.
Every time train departs from or passes through the station, a platform supervisor warned us.
I could see that mascot of the Tokyu Corporation is put in the train conductor room.
The trains seems to be running between Hiyoshi and Meguro on Tokyu Meguro Line.
Since all of the current trains on the line have through service to Tokyo Metro Namboku Line, Toei Mita Line, and Saitama Kosoku Railway, section of the trial running will be extended to these lines.
