Introducing
The E531 series (E531系, E531-kei) (E531けいでんしゃ/E531-keidensha or JR東日本E531系電車/JR Higashinihon E531-keidensha) is a type of dual-current self-propelled trainset, used for commuter and suburban services and operated by the East Japan Railway Company (JR East) in northeastern Greater Tokyo since 2005.
The E531 series was designed to replace the aging 403/415 series of steel cars used on the Jōban and Mito lines. Its other objective is to improve operating speed following the opening of the Tsukuba Express in 2005.
Console detail
Apart from the pocket watch and the door-closing indicator in the center of the console, there are 2 displays. In addition, on the left, above the console, is the dial for the ATS-Ps, which will not be used.

- Brake cylinder pressure (BC)
- Main air reservoir pressure (MR). Note that if this falls below the red zone (780kPa), the compressor starts up.
