Tokyu Ikegami Line 7000 Series Train on 2017 October 9th: 9

A Tokyu 7000 Series car is 18m long and has three doors. Many cars that appear in my photo stream are 20m long and have 4 doors. 18m three door car has a slightly longer distance between two doors. So, 7000 series has two almost square windows between two doors, while a 20m four door car has a rectangle window long from side to side.
