2022 diamond revisions have been out for some time. Anything spicy going on with JR Central/West, subways, private railways? I spent some time going through JR East's changes.
The biggest change is 209-3500 and E231-3000 going fully wanman. Since E233-0 still uses a conductor, Chuo-Rapid to Hachiko/Itsukaichi thru services are discontinued. These trips started with the Kawagoe Line's electrification in 1996 with the 201 series. RIP being able to see E233s alongside diesel trains. The GV-E400 did some testing on the diesel portion of the Hachiko Line back in Stepember so hopefully it will get GNSS-capable rolling stock in the future.
Here are some of the other JR East revisions that got my attention:
> E7 rollout on Joetsu Shinkansen
> Yamagata/Akita Shinkansen switch to 100% reserved seating
> Various Tohoku Shinkansen and Azusa/Kaiji schedule modifications that I'm too lazy to describe in detail
> An additional Swallow Akagi trip on the Takasaki Line
> Shonan Liner trips to/from Shinjuku now stop at Osaki
> A handful of LtdExp trips (Shonan Liner, Azusa/Kaiji, Hitachi/Tokiwa) extended to Tokyo or Shinagawa in the case of Joban Line
> More N'EX trips stop at Chiba Station. 4->16/day EB and 3->13/day WB
> Joban Rapid trips to/from Ueno-Tokyo Line increased from 2tph to 3tph during midday
> Nambu Line gets Rapid service extended by an hour on weekends/holidays
> E131-500/600 series debut. Replaces 205-600 series on the Nikko Line/north Utsunomiya Line, and 205-500 series on the Sagami Line.
> 23 N'EX trips start/end at Shinjuku instead of Ikebukuro/Omiya
> EB Chuo-Sobu Local peak frequency from 23tph to 19tph
