context_page_description: The 185 series is an electric multiple unit train type operated by East Japan Railway Company primarily on middle-distance limited express services centering on Tokyo.
  The class is broadly divided into two variants: 185-0 series for use south-west of Tokyo, and 185-200 series originally for use north of Tokyo.
context_section_description: Between 1993 and 1998, the original Japanese-style toilets in cars 1, 4, and 7 of the Tamachi-based B sets were replaced with western-style toilets.
  The nine sets remaining at Shin-Maebashi depot were all refurbished between September 1995 and November 1996. Refurbishment involved replacing the original flip-over seating in standard-class cars with rotating/reclining seats. Externally, the sets were repainted in white with yellow/grey/red blocks intended to represent the Jōmō mountain range together with "EXPRESS 185" markings below the windows.
  In March 2006, the Shin-Maebashi-based sets were transferred to Ōmiya depot, becoming sets OM01 to OM09.
  Between March and June 1996, three of the 7-car sets based at Tamachi (B3 to B5) were fitted with ATC equipment for use on the Keihin-Tōhoku Line and Negishi Line when operating on Hamakaiji services. These sets were upgraded with D-ATC equipment between January 2006 and March 2007.
