Ivalion Metrorail, commonly but incorrectly referred to as Ivalion Metro is the name for the rapid transit rail system serving Ivalion, Califia, and its suburbs. It is owned and operated by the Ivalion County Transportation Authority. Established in 1947, the Metro system has grown to consist of six rapid transit lines, one rapid light rail line, and one long distance rapid transit line.
The Ivalion Metro is the busiest metropolitan mass transit sysetm in Ivalice. In 2009, the Ivalion Metro carried 455 million passengers, and averages 1,248,000 riders per day. The entire system, with the sole exception of the LDRT Saint James Line, operates under a flat fare, 2.50i. Fare is collected on entry, and customers exit the system through fare-paid barriers.
Serious plans for a subway in Ivalion were first considered during World War II. In the early 1940s, workers travelling from the western parts of the city and suburbs to the industrial areas and seaports along the oceanfront strained the local road and streetcar network. Traffic worries led to the formation of a Transit Study Commission, which designated a route along Terraplén from Center Street in the west to Fort Exeter, at the time a military garrison, in the east. The subway construction and necessary bonds were put to a referendum in the 1942 general elections, and passed with a majority, with construction beginning November 1943. Construction was completed in May 1947, and the initial line was opened on June 5, 1947, to critical acclaim. Original estimates for ridership were quickly surpassed, leading to an initial shortage of rolling stock.
