, October 2016 The rail line
right-of-way used for the first operational section (Phase 1) of the S Line was originally built in 1900 by the
Denver and Rio Grande Western Railroad (D&RGW) as the Sugar House Branch.
Southern Pacific purchased the D&RGW properties, which in turn folded into the
Union Pacific Railroad (UP). UTA purchased the right-of-way and the rail line in 2002 and UP officially
abandoned the rail line in 2005.
Federal funding for the project was applied for in 2009. Of the estimated $55 million project cost, Salt Lake City provided $2.5 million in funding and applied for $35 million in federal
Transportation Investment Generating Economic Recovery (TIGER) funding. The project was granted $26 million TIGER II funding on October 20, 2010. Construction began on May 9, 2012. In late August 2013, UTA announced that the streetcar would be called the
S Line According to UTA, "The S Line was named in honor of the streetcar's two founding cities, Salt Lake and South Salt Lake, as well as the Sugar House neighborhood it calls home." The streetcar plan was developed from an earlier proposal for a heritage trolley line which was begun in 2002. The original idea was reported in the
Deseret News on May 16, 2003. However, at that time rail service was not projected to reach Sugar House before the year 2030. Since most of Phase 1 was built within the existing railway right-of-way, very minimal additional property acquisition was necessary. The integration of the S Line at Central Pointe station required the addition of a second passenger platform (a
side platform) to be built just southeast of the existing
island platform for the TRAX lines. Transfer between the two modes of transportation only requires a short walk between the two platforms, but the S Line platform is only accessible from the southern end of the TRAX platform. Although years in development, the S Line is the first streetcar line to operate in the state of Utah in over 50 years. A two-block section of the S Line, between 300 and 500 East, was
double-tracked in early 2019 at a cost of $5.9 million to address frequency needs spurred by growing ridership.
Double-tracking When the S Line opened in December 2013, the line was almost entirely
single-tracked, with passing tracks at the 500 East station where the two cars typically operating on the line could pass each other. This layout enabled 20 minute frequencies on the line. In June 2017 it was announced that Salt Lake County would provide $4.5 million, and the federal government would provide $1.9 million through its Congestion Mitigation and Air Quality Improvement program, to
double-track the portion of the S Line from just west of the 300 East station, through to just east of the 500 East station, enabling improved 15 minute frequencies on the line. Construction began in June 2018, and was completed in April 2019. == Future plans ==
