>>1134693Well, there are only 24 cars (4 sets of 6-cars) left in two of JR East's yards with 3 sets in Toyoda and 1 set in Nagano. I'd assume when JR East builds more E353 Series EMU to standardize its fleet for all the Chuo Main Line express trains some E257 Series EMUs will probably remain to replace the 183 Series for seasonal duties.
