Layout
Iyoshi Station is an above-ground station with a station building adjacent to a single side platform, and connected to an island platform by a footbridge. Platforms are numbered in order from the station building. Platform 1 has a straight through-line structure (there is no speed limit, but it is immediately to the west). Since there is a curve of R300 at the station, outbound trains are slowed down, but there are currently no regular trains passing through this station). Normally, both inbound and outbound trains arrive and depart from Platform 1, and only exchange trains and return trains use Platforms 2 and 3. This station is formally the boundary between non-electrified and electrified sections of the Yosan Line (most trains coming from the direction of Iyo-Hojo terminate at Matsuyama Station), and the west side of this station (towards Iyo-Nagahama and Uchiko) is non-electrified. The station building is large and tile-covered.The front portion has been refurbished and has ticket counters and automatic ticket vending machines.
History
The station was opened on 27 February 1930 as Minami Gunchū Station (南郡中駅) along with the extension of the Sanyo Line from Matsuyama. About a month later, the line was renamed to the Yosan Line .At that time, the station was operated by Japanese Government Railways (JGR), later becoming Japanese National Railways (JNR). The station was renamed to its present name on 1 April 1957. A major change in this station was the opening of a new line from Mukaihara Station to Uchiko Station in March 1986.With the privatization of JNR on 1 April 1987, control of the station passed to JR Shikoku.[3][4]
