TRAX (light rail)
TRAX is a light rail system in the Salt Lake Valley of Utah, in the United States, serving Salt Lake City and many of its suburbs throughout Salt Lake County. The system's official name, Transit Express, is rarely, if ever, used. The system is operated by the Utah Transit Authority. All TRAX trains are electric, receiving power from overhead wires.
TRAX has 52 stations on three lines. The Blue Line provides service from Downtown Salt Lake City to Draper. The Red Line provides service from the University of Utah to the Daybreak Community of South Jordan. The Green Line provides service from Salt Lake City International Airport to West Valley City. In, the system had a ridership of, or about per weekday as of.

Former
To handle the increased crowds during the 2002 Winter Olympics, 29 Kinki Sharyo LRVs were borrowed from the Dallas Area Rapid Transit between 2001 and 2003.29 UTDC LRVs were purchased second-hand from the Santa Clara VTA in 2004 and refurbished for service on TRAX. These were withdrawn from service in 2018.
History
In 1984, the UTA, Utah Department of Transportation, and the Wasatch Front Regional Council conducted a joint study known as the "I-15/State Street Corridor Alternatives Analysis", which concluded that automobile traffic on those two roadways would increase and become more congested over time. The construction of a light rail system parallel to the interstate emerged as the UTA's preferred option to decrease congestion. In 1990, a state law was passed allowing Salt Lake County to increase local sales tax by 0.25 percent, with 75 percent of the revenue going to construction of the light rail system and the other 25 percent to expand Interstate 15, dependent on a referendum approving the increase. The referendum was held on November 3, 1992, and it failed, with 57 percent of county voters rejecting the measure.Despite the referendum result, the UTA agreed in January 1993 to purchase 23 miles of trackage from Union Pacific, with most of the cost covered by federal funding. With the local tax increase having been rejected, UTA depended on funding from the Federal Transit Administration to construct the line. Congress rejected that funding in June 1995, but the urgency of building transit in the area grew later that month when Salt Lake City was awarded the 2002 Winter Olympics. In August 1995, the UTA and FTA signed a Full Funding Grant Agreement, requiring the UTA to construct the line n=by December 2000. The FTA offered to cover 80 percent of construction costs, but the agreement was binding whether Congress approved the federal grants or not.
After federal funding was approved, the system was given the name TRAX on March 3, 1997, and a groundbreaking ceremony was held on April 10. The first line, running from downtown Salt Lake City south to Sandy, opened on December 4, 1999. A branch extending from downtown to Rice–Eccles Stadium was completed on December 15, 2001, two months before the Olympic opening ceremony was held there, and further extended to the University of Utah Hospital on September 29, 2003.
An extension to the Salt Lake City Intermodal Hub was completed in April 2008. In August 2011, two extensions to South Jordan and West Valley City were completed. With the opening of these two extensions in 2011, the TRAX lines were renamed as colors instead of destinations, with the Blue Line running from the Salt Lake City Intermodal Hub to Sandy, the Red Line running from the University of Utah Medical Center to the Daybreak community in South Jordan, and the Green Line running from the intermodal hub to the West Valley Intermodal Hub.
In 2013 the Green Line was realigned slightly north and away from the Salt Lake City Intermodal Hub, allowing for the opening of the extension to the Salt Lake City International Airport. Several months later, in August 2013, the Blue Line was extended further south to Draper. The extensions to South Jordan, West Valley City, Draper, and the Airport were funded in part by a Salt Lake County sales tax increase that would pay for all four of the proposed TRAX extensions. A letter of intent signed with the Federal Transit Administration on September 24, 2007, secured the remaining funding for the light rail lines.
Both the University Line and its extension to the University Medical Center were completed ahead of schedule. A daily ridership of 15,000 was expected for the initial line in 1999. By the beginning of 2008, the expanded system of served an estimated 40,000 passengers each day. Ridership for the fourth quarter of 2012 was reported to be at 60,600, making it the ninth-busiest light rail system in the United States.
Light rail in the Salt Lake Valley was first seriously discussed in the late 1980s to provide an alternative to traffic congestion on I-15, but the idea was met with criticism. On October 10, 1988, Congress approved $5 million in funds to preserve land along the proposed light rail corridor. Funding for the light rail line, however, remained uncertain. After Salt Lake City won the bid for the 2002 Winter Olympics in 1995, UTA used the city's host status to accelerate obtaining funding through the Federal Transit Administration. Construction began in 1997. Protesters at the groundbreaking insisted light rail would be dangerous and a waste of money. Public opinion remained divided and businesses on Main Street in downtown Salt Lake City suffered during the construction period.
After the north–south line opened in late 1999 with sixteen stations, ridership expectations were quickly met. The system was enthusiastically embraced by valley residents, to the surprise of many, and once-skeptical communities soon began clamoring for extensions.
Funding for the University Line to Rice-Eccles Stadium allowed it to be completed in 2001 with four new stations, ahead of schedule and the Olympics. An extension to the University Medical Center that added three new stations was completed on September 29, 2003, fifteen months ahead of schedule. An infill station at 900 South in Salt Lake City was constructed in 2005, and a second infill station, at 9400 South in Sandy, opened in August 2006. On December 13, 2006, UTA's board of trustees voted to change the name of the station next to the Delta Center to "Arena" in response to the renaming of the Delta Center to EnergySolutions Arena.
On February 23, 2006, plans for extending the main line westward to the current Salt Lake City Intermodal Hub near the Gateway were approved. Two stations were built near the Gateway, as well as one at the Salt Lake Central Station. They opened in April 2008, bringing the total number of stations to 28.
UTA has two service centers for TRAX maintenance: the Midvale Rail Service Center, which is just off the Red Line in Midvale, southwest of its junction with the Blue Line, and the Jordan River Service Center, which is just off the Green Line northeast of River Trail. The Jordan River building was originally an old warehouse for ZCMI, which had recently ceased operations and was renovated into a rail service center in 1999. The Midvale Center was similarly repurposed from a former warehouse around the time of the Red and Green lines opening in 2011, it was also built to handle UTA's brand new Siemens S70 LRV's. Utah Railway and the Savage Bingham & Garfield Railroad both operate freight service over TRAX tracks via trackage rights.
An additional infill station, 600 South Main Street in Salt Lake City, along all three lines, opened on July 26, 2022. The station was part of the initial plans for the system, but the demand was not at the level needed for a station until recently.
FrontLines 2015
On September 21, 2006, a property tax hike proposal was replaced with a general transportation quarter-cent sales tax hike that was voted on and approved on November 7 of that year. On December 21, 2006, the Salt Lake County Council created a priority list for the sales tax, saying TRAX and commuter rail should take priority. A letter of intent signed with the Federal Transit Administration on September 24, 2007, secured the remaining $500 million in funding for the light rail lines. These funds were used to finance the FrontLines 2015 expansion project, which added four TRAX extensions by 2015.In order to support planned TRAX expansion, UTA ordered 77 Siemens S70 light rail vehicles from Siemens AG. It is the company's largest light rail contract in the United States to date.
In 2008, construction began on two new extensions: one extension of through West Valley City and another extension of through the southwest portion of the Salt Lake Valley. Both extensions were debuted in ceremonial openings on August 2, 2011, and permanently opened for regular service on August 7. Both extensions were completed ahead of schedule and under budget. Upon completion of these expansions UTA adopted a color-code line names in place of their old destination-based line names.
After the first year of operation, ridership on these portions of the Green and Red lines was less than was projected by UTA. However, UTA has stated the projected ridership was for the year 2015. Since these lines were opened for service years earlier than originally planned, the anticipated growth on the west side of Salt Lake Valley has just not happened, yet. UTA affirms that by 2015 ridership will meet the original projections.
A line from Salt Lake City International Airport to the University of Utah was in the original plans for the system to be completed before the 2002 Winter Olympics, but funding shortages only allowed the eastern portion to be constructed. The airport line eventually came to fruition, however, and ground was broken on October 22, 2008. The extension opened on April 14, 2013, adding and six additional stations to the Green Line, including a transfer station to the FrontRunner.
On November 14, 2006, the Draper City Council approved the TRAX extension into that city. Neighbors in the area have continually fought the route suggested by UTA. The route follows an old rail line and UTA already owned the right of way. An alternative route that would run down the middle of State Street was also studied by UTA. Use of the UTA right of way for the line was challenged in court and later approved by the Utah Supreme Court on July 12, 2008. UTA published a draft Environmental Impact Statement for the new line that names the UTA right of way as the preferred route. The extension's first phase, which includes and three new stations, opened on August 18, 2013.
