For the upcoming 2020 Tokyo Olympics, JR East will build 49 (so 50 in total) E235 sets to replace the 52 E231-500 sets currently serving the Yamanote Line starting next year. The current E231-500 sets will be modified to serve the Chuo-Sobu Line (number of them actually being modified are unknown, but 2 of the 52 sets have already been modified), not sure what will happen to the current 209-500 Series sets and the current E231-0 Series sets
This is the current list of rolling stock used for the C-S Line stationed in the Mitaka Rolling Stock Center (all sets have 10 cars)
209-500: 13 sets (1998~)
E231-0: 43 sets (2000~)
E231-500: 2 sets (Former Yamanote Line sets, 2015~)
209-950 > E231-900: 1 set (1998~)
Sauce for the announcement:
