Operation research of To-Yama E231/E233 series 10-car sets

The table below represents the research of operations of E231-1000 series or E233-3000 series 10-car sets (base sets) based at Oyama Depot (a.k.a. To-Yama E231/E233 10-car sets). These cars serves on the lines such as the Utsunomiya and the Takasaki Lines.

* The number (from 1 to 59) is the original number for convenience.
* The operation may be changed for various reasons. Since there are several operation changes at Koganei, the order of operations in the table below may change.
* E231 and E233 series are used interchangeably. No operation for E231 only or E233 only exists.
* This data is based on the original research, and is UNOFFICIAL.
* For the operation changes due to accidents or any, the E231 or E233 series based at Kōzu Depot (Kotsu E231/E233) may be used for operations of Yama E231/E233 and vice versa (it may continue for a few days).

This data is based on a lot of sightings, especially on ‘東海道線東京口運用調査班掲示板’.
