The Santa Ana Line began at the old Southern Pacific Station (now demolished) at Terminal Street just south of the current Santa Ana train station, and traversed downtown Santa Ana via 4th Street. Service to Orange County was terminated in 1950 due to the increasing use of automobiles and buses, and the original tracks through town were removed and paved over. West of downtown Santa Ana, the original wide right of way – purchased by OCTA after its abandonment – remains as a strip of vacant land extending diagonally across Orange County's cardinal street grid, from Santa Ana northwest to Cypress/La Palma on the Los Angeles County line. Although OCTA has allowed some temporary uses (such as parking) in the historic right of way, and most of the tracks have been removed, the authority always intended to return this corridor to transit use in the future. The first proposals for a modern, second-generation light rail system serving north Orange County appeared in the 1990s. The CenterLine project would have created several light rail lines, including a main line running from Fullerton via Santa Ana to Irvine. It would have included service along the current OC Streetcar route between the Santa Ana train station and Bristol Street, but not along the diagonal West Santa Ana Branch right-of-way. Multiple branches were also proposed for the line to serve other areas of Orange County; most of the lines would have been elevated. The initial 1992 proposal called for of light rail, which due to political opposition was reduced to by 2001, and by 2004. The CenterLine was opposed mainly due to its high cost (more than $1 billion for the segment between Santa Ana and John Wayne Airport) and was ultimately canceled in 2005. A streetcar along the current, east-west route (the "Santa Ana-Garden Grove Fixed Guideway Corridor") was first proposed by OCTA in 2006. The streetcar was the result of OCTA's "Go Local" initiative, which offered funds for Orange County cities to study potential new transit links to existing Metrolink rail stations. The Measure M2 sales tax increase, which will be partly used to fund transit projects, was also passed in 2006. In 2008, the cities of Santa Ana and Garden Grove partnered with OCTA to develop the project. The design was modeled after street-running light rail services of the Portland Streetcar (Portland, Oregon) and TRAX (Salt Lake City, Utah). Environmental reports were completed and the project qualified for federal funding status by 2015. Former President Barack Obama included $125 million for OC Streetcar in the 2016-17 federal budget under the Major Capital Investments (New Starts) program.
