特別な役目を果たしに長距離の移動？！転用や改造とは違った今までに無い動きとは

The E657 series, normally operated on the Joban Line's limited express trains, the Hitachi and Tokiwa, based at the Katsuta Depot, made its first appearance in an unrelated area. I took a look at the K11 formation that happened to be there while I was there, and then saw it off. It seems to be related to the Luna Azul, a night train scheduled to begin commercial operation between Shinagawa and Aomori in early 2027. #LimitedExpressTrain #Hitachi #Tokiwa #E657series #NightTrain Twitter   / kitsunekita0121
