The207 series (207系,207-kei) is a DCelectric multiple unit (EMU) commuter train type operated byWest Japan Railway Company (JR-West) in theKansai Region of Japan since 1991.

This train bears no relation to the207 series built byJNR and operated byJR East until 2009.^[2]

The 207 series was developed for use on theKatafuku Line (now known as the JR Tozai Line), and also to be the standard commuter train type for JR-West.^[1] The type was introduced into service on 30 April 1991,^[3] replacing ageing101 series and103 series EMUs operating on theFukuchiyama Line and theKatamachi Line.^{[3][additional citation(s) needed]}

The trains were built jointly byHitachi,JR-West (Goto Factory),Kinki Sharyo, andKawasaki Heavy Industries.^[4]

With the introduction of the321 series fleet from 2005, the 207 series fleet was re-liveried from its original two-tone blue scheme to a navy-and-orange color scheme, matching that of the 321 series.^[3][5]

On 22 September 2014, JR-West announced that the 207 series fleet would undergo a program of refurbishment, aiming to improve the fleet's safety, efficiency, and accessibility.^[6] 0-subseries set Z22, the first set to be refurbished, returned to service on 17 November 2014.^[7]

During the refurbishment program, the interior was fitted with wheelchair spaces, enlarged seat partitions, newly introduced intermediate seat partitions to make way for vertical grab bars, and LED lighting. External changes include the use ofHID headlights, gangway door-mounted wipers, and end car-mounted safety fencing. In addition, the fleet was equipped with fault detection technology, and much of the existing electrical equipment was overhauled.^[6][8]
