Following the announcement of a new Shinkansen type due to enter service on the Tôhoku Shinkansen in 2030, let's have a quick look at the oldest trains on the line, that will be replaced.
The E2 is the oldest high-speed train type that JR East owns, and many examples have already been retired. Built for the slower Jôetsu route to Niigata, they operate the Yamabiko and all-stop Nasuno services.
The E10s will also replace E5 sets. This sounds unreal to me, the E5 is the pinnacle of Shinkansen, still the only train running at 320 km/h in Japan (coupled with the E6, when the couplings work), and still young, having been introduced in 2011! Granted, by 2030, the first E5s will be nearly 20 years old, but they're probably not going to disappear completely in one go.
