約2ヶ月の期間で完成した改造とは？！編成の外観や内装を一通り見てみると

JR East's E233 series commuter trains, which operate in urban areas of the greater Tokyo metropolitan area, have been reported to be undergoing modifications and then reassigned to the Chiba area, and we've seen their progress covered many times. Now, the first train has appeared on the main line. What exactly has it been like? After getting a glimpse of the train, we were able to see the entire formation. #E233Series #CommuterTrain #Modification #DepotTrain #Chiba #Boso Twitter   / kitsunekita0121
