[5] The line became largely unused after a 1985 track-sharing agreement between the Union Pacific and the Denver and Rio Grande Western.

The Salt Lake City Southern Railroad was formed to serve these customers and manages the freight traffic over the Blue Line.

Upon crossing East 11400 South it leaves Draper and enters Sandy and immediately reaches Crescent View.

[1] This station is several blocks east of Sandy City Hall and the South Towne Center Mall.

Just after crossing East 9400 South the Blue Line reaches an infill station, Sandy Expo,[8] which provides service to Rio Tinto Stadium in addition to the Mountain America Exposition Center.

Then it crosses over the East Jordan Canal and immediately reaches Historic Sandy.

The previous station for the Red Line is Bingham Junction, having started in the Daybreak community of South Jordan.

(The Red Line also provides access to UTA's Lovendahl Rail Service Center which is located just west of I-15.)

Upon crossing over Big Cottonwood Creek, the lines also leave Murray and briefly enter unincorporated Salt Lake County.

From this station, the lines head directly north until they cross West 3300 South (SR-171) and immediately reach Millcreek.

The previous station for the Green Line is River Trail, having originated in West Valley City.

(The S Line provides streetcar service east to the Fairmont stop in the Sugar House neighborhood of Salt Lake City.)

At South Main Street, the lines turn north and continue down the center median of that street and cross West 600 South (Martin Luther King Jr Boulevard/SR-269 eastbound), pass between the Grand America Hotel and the Little America Hotel, and then cross West 500 South (Cesar E Chavez Boulevard/SR-269 westbound).

This station is in the middle of the new City Creek Center commercial and residential development.

At the north end of South Main Street the two lines turn west down the middle of West South Temple Street for a little more than a block before reaching the next station, Temple Square.

Continuing down the median of West South Temple Street the lines reach [[Arena station {Utah Transit Authority))|Arena]] (formerly Delta Center).

This station is immediately north of Delta Center, east of the Union Pacific Depot, and south of Ensign College.

However, an extension opened on April 16, 2008, which provided access to the Salt Lake City Intermodal Hub and the new FrontRunner commuter rail train.

[10] Salt Lake Central provides access to the FrontRunner, as well as the Amtrak California Zephyr, and Greyhound Lines.

The Zone covers an area of approximately thirty-six city blocks and the boundaries are roughly North Temple, 200 East, 500 South, and 400 West.

TRAX stations within the Zone include Arena, City Center, Courthouse, Gallivan Plaza (mistakenly identified as "Gallivan Center Station" on the Free Fare Zone map), Planetarium, and Temple Square.

In addition, the Free Fare Zone also includes the area of the State Capitol (north to 500 North), the bus stops on 400 South between 200 East and 300 East, and three additional TRAX stations: Library, Old GreekTown, and Salt Lake Central.

[14] The following table lists the current stations of the Blue Line, from north to south.

All Blue Line stations have mini-high platforms and train operators may need to assist riders with their use.

Some riders have complained they can't roll their wheelchair up the steep ramps rendering the Blue Line inaccessible to them without operator assistance, and UTA policy does not allow passengers with strollers or luggage to use access ramps, forcing them to lift those items up the stairs of the train.

In 2023, UDOT revealed its intention to build a new light rail line at the former Utah state prison site.
