両数を減らすと波動用で臨時列車に？！改造後に転属と噂がある編成にもう見られた変化とは

The limited express trains on the Joban Line system, such as the Hitachi and Tokiwa, are operated by E657 series trains belonging to the Katsuta Rail Yard. One of these trains was taken out of service a few days ago due to inexplicable movements at its home depot, leading to rumors that it would enter the factory for modifications before being transferred. After learning about this series of events, I photographed it at a station on a route it doesn't normally use, as it was heading from the rail yard to the rail factory. There has been almost no official announcement, and this is based purely on rumors and speculation, so it's necessary to continue monitoring the situation. #E657series #Hitachi #Tokiwa #LimitedExpressTrain #TransferTrain Twitter   / kitsunekita0121
