We have to ask: how long will JR East keep the 211系? The newest train sets are at least 30 years old and approaching the point of needed replacement. My guess: we'll see a big order for both the E129系 and E131系 to replace the old train sets, with the E129's assigned to routes that experience colder climates.
I've seen a lot of your movies and AUNZ RAILFAN and ayokoi. And I have one big question. Where are the passengers? Most stations are empty. In my country, many railroads have been closed because people choose cars.
