June 2015
An article about UTA's implementation of UHF RFID tags to help it track its equipment, included the following, "UTA serves 2.2 million people throughout the Salt Lake City area, and operates 700 buses, 400 vans, 146 light-rail cars and 60 commuter-rail cars. Altogether, its rail vehicles travel 200 miles of track." (RFID Journal, June 12, 2015)

In 2013, UTA saw a year of record ridership with more than 44 million boardings. UTA also opened the S-Line and concluded its FrontLines 2015 program under budget and two years ahead of schedule, with the completion of TRAX lines to Draper and the Salt Lake International Airport. (Utah Transit Authority news release dated June 25, 2014, on the occasion of American Public Transportation Association naming the Utah Transit Authority as Outstanding Public Transportation System of 2014)

January 2008
UTA moved into its new offices, located at 669 West 200 South, just west of the transit hub. As many as 240 (increasing to 400) workers were expected to move into the new building, bringing together all of the personnel to see to the timely completion of two commuter rail lines, and four light rail lines, all by 2015. (Deseret News, December 4, 2007)

September 17, 2003
UTA and Union Pacific signed a final agreement for UTA to take formal ownership of the former Union Pacific diesel shop complex near 800 North and Beck Street. A ceremony was held on September 17 to unveil a new UTA sign on the east face of the building. Taking ownership of the building would save UTA $20 million to build a new facility, and with plenty of space available, the facility would also house numerous other UTA activities, including the dispatch center for the commuter rail service when it started in 2008. (UTA press release dated September 17, 2003; Deseret News, September 19, 2003, "Wednesday morning")

UTA tested a prototype rail diesel car, built by Colorado Railcar, based in Lupton, Colorado. The cars was tested along UTA's track between Sandy and Draper, which had not yet been converted for light rail use. (Deseret News, April 11, 2003; May 28, 2003)

September 20, 2002
A ceremony was held on the steps of the Utah state capital, for the signing of the $185 million check to Union Pacific. In attendance were Utah governor Mike Leavitt, U. S. congressmen Jim Matheson and Chris Cannon, Union Pacific chairman, president and CEO Richard Davidson, and UTA general manager John Inglish.

The original agreement for the sale was signed between UTA and Union Pacific on Thursday January 17, 2002. (Deseret News, January 16, 2002; January 17, 2002)

Negotiations for the sale began in March 2002, and included over 20 separate agreements, covering the purchase, right-of-way access, and environmental issues. (Deseret News, October 18, 2001)

UTA originally asked that UP share its track, which UP would not allow. Instead, UP would sell UTA a 20-foot corridor adjacent to its freight tracks, and the agreement for the adjacent corridor was signed on February 5, 2001. (Utah League of Cities and Towns, legislative Committee Meeting Minutes, February 19, 2001)

The corridors in the sale included:

The facilities in the sale included:

In a related note, the sale of the former intermodal yard depended on Union Pacific being able to build a new 300-acre intermodal and automobile unloading ramp facility on Salt Lake City's west side, at 5600 West and 800 South. On July 29, 2002, the Salt Lake City Council approved UP's plans for the new facility. The new facility would allow Union Pacific to close its intermodal ramp at Becks Street, and its automobile unloading ramp at Clearfield. (Deseret News, July 30, 2002; Salt Lake Tribune, July 30, 2002; Trains News Wire, August 1, 2002; UPOnline, August 6, 2002)

The location for the new "Intermodal Freight Hub" was negotiated by UTA and was on land owned by The Church of Jesus Christ of Latter-day Saints. (Salt Lake Tribune, July 6, 2002) The original application and petition was presented by Union Pacific and UTA to the Salt Lake City Council on June 4, 2002, and the council set a public hearing to be held on July 2, 2002. (Memorandum, Salt Lake City mayor to Salt Lake City Council, dated May 31, 2002, which included specific improvements and street closures by the applicants.)

May 15, 2002
Provo City officials held a ceremony to dedicate a new passenger depot in Provo at 600 South and 300 West.

Commuter Rail and Light Rail, What's The Difference?

UTA's Frontrunner falls under Federal Railroad Administration (FRA) jurisdiction, and TRAX falls under Federal Transit Administration (FTA) jurisdiction. There are no apparent plans to connect TRAX with Frontrunner, including (as some have mentioned) sharing the Warm Springs maintenance facility.

A good definition about the differences between commuter rail (UTA's Frontrunner) and light rail (UTA's TRAX) comes from Railway Age:

Jurisdiction covering urban transit properties, such as "light rail", subways and elevated systems, traditionally has fallen to the Federal Transit Administration (FTA), while Federal Railroad Administration (FRA) took care of Class I freight railroads, Amtrak, and "commuter rail" systems. Where an "urban" system physically connects with another railroad -- freight or passenger -- however, FRA assumed oversight. The bistate New York/New Jersey Port Authority Trans-Hudson (PATH) rapid transit system, an urban circulator in New York City, falls into this category, in part because its physical plant connects with Amtrak's Northeast Corridor in New Jersey.

FRA's oversight, approved by Congress, expanded significantly under a joint statement issued by FRA and FTA on July 10, 2000. FRA's "Policy on Jurisdiction Over Passenger Operations" states in part: "Under Federal railroad safety laws, FRA has jurisdiction over all railroads except rapid transit operations in an urban area that are not connected to the general railroad system of transportation. . . . Within the limits imposed by this authority, FRA exercises jurisdiction over all railroad passenger operations, regardless of equipment used, unless FRA has specifically stated an exception to its exercise of jurisdiction for a particular type of operation." (Railway Age, Volume 209, Number 7, July 2008, page 17)

TRAX and Frontrunner at UtahRails

(This information was first published in the blog on June 7, 2013) was started in late 2001. At that time the only Utah Transit Authority (UTA) railroad activity was its TRAX light line between Salt Lake City and Sandy, 15 miles to the south. In an early entry, I included some basic information about when the line was started (1997), and when the first trains were operated (1999).

Over the past 10-12 years, as I would see a news story, or come across the odd piece of information here or there, I would print it out and file it for future updates. As TRAX extensions were added to the University and the new Salt Lake Central station, I also added the basic information. And when the FrontRunner commuter rail service was started (2005) and opened to the public (2008), the file kept getting thicker and thicker. I was receiving weekly updates from friends working for the contractors, which included weekly milestones as they were reached during the construction phase. In the meantime, UTA continued to add more TRAX light rail lines, and I tried to keep up with the changes, dutifully printing the items out and filing them.

New TRAX lines to West Valley, Mid-Jordan, and the Airport Line were completed in 2011 and 2013. The extension to Draper was completed in 2013, and the Sugar House streetcar line was also completed in 2013.

I had been adding basic information to the various UTA web pages, and creating new pages as needed. But by now, the stack of printed references had grown to eight inches. It was time to get to work. It has taken over two weeks of reading and collating, then entering dates and events to the various UTA, TRAX and FrontRunner pages, but now it's done, and all that paper has been sent to recycle.

Frontrunner and TRAX Photos at UtahRails

Construction of FrontRunner North (Salt Lake City to Ogden) was started in late July 2005 and was opened to the public in April 2008. I began receiving photos in April 2006. By the time the line between Salt Lake City and Weber County was opened in April 2008, I had accumulated over 800 photos, in various forms and formats. It took several days to extract photos from PDF files, and from Powerpoint presentations, then date them and name them to show where each was taken. All 844 photos of FrontRunner North being built have been uploaded to their own photo album.

Construction of FrontRunner South (Salt Lake City to Provo) was started in August 2008 and was opened to the public in December 2012. I began receiving photos soon after work started, and by the time that test trains were running in August 2012, I had gathered together over 600 photos, again in various formats contained in PDF files and presentations. These 634 photos have also been uploaded to their own photo album.

During the construction of new TRAX lines in 2011 to 2013, I was receiving several PDFs and Powerpoint presentations for each of the TRAX light rail lines, and after extracting the photos from these sources, as well as some of the weekly email updates, and compiling them into separate sets, I have uploaded over 440 photos into their separate albums.
