DispositionOperational, based in Cheyenne, Wyoming, at the steam shop

The locomotive operated in revenue service until 1959. It was donated to the Railway and Locomotive Historical Society in late 1961 and thereafter displayed in Fairplex in Pomona, California. In 2013, Union Pacific re-acquired the locomotive and launched a restoration project at their Steam Shop in Cheyenne, Wyoming.[4] In 2019, No. 4014 ran under its own power for the first time in over 59 years, becoming the largest operational steam locomotive in the world.[5] Part of Union Pacific's heritage fleet, it now operates in excursion service, in addition to hauling revenue freight during ferry moves.

DesignEdit

The Big Boy class was developed by Union Pacific and ALCO to overcome problems with its 4-6-6-4 Challenger-class locomotives.[6] UP determined that its goals for the new class could be achieved by making several changes to the existing Challenger design such as enlarging the firebox to about 235 by 96 inches (5.97 m × 2.44 m) (about 155 sq ft or 14.4 m2), lengthening the boiler, adding four driving wheels, and reducing the diameter of the driving wheels from 69 to 68 in (1,753 to 1,727 mm).[1]

The Big Boy was articulated like the Mallet locomotive design, although without compounding.[7] It was designed for stability at 80 miles per hour (130 km/h), allowing for a wide margin of reliability and safety, as the locomotives normally operated well below that speed in freight service.[8] Peak horsepower was reached around 35 mph (56 km/h); optimal tractive effort was reached around 10 mph (16 km/h).[8] Longer than two buses, heavier than a Boeing 747, the Big Boy has the longest engine body of any reciprocating steam locomotive and was likely the heaviest steam locomotive ever built.[9]

HistoryEdit

Revenue service and retirementEdit

 
UP No. 4014 on static display at the RailGiants Train Museum in Pomona, California, in 2005

ALCO built No. 4014 in November 1941 and delivered it the following month to Union Pacific, which placed it in revenue service.[1] No. 4014 was part of the first group of 20 Big Boys, classified as 4884-1.[3] Designed to haul 3,600-ton trains over Utah's Wasatch Range, No. 4014 and the 24 other Big Boys routinely pulled trains of up to 4,200 tons.[1] No. 4014's last routine repairs took place in 1956.[10]

No. 4014 completed its final revenue run on July 21, 1959, just hours before the last revenue run by any Big Boy.[1] It had traveled 1,031,205 miles (1,659,564 km) during its twenty years of revenue service.[1] Union Pacific retired No. 4014 on December 7, 1961.[8] All of the Big Boys were retired by 1962, their duties assumed by diesel locomotives and gas turbine-electric locomotives (GTELs).[1][11] That same year, Union Pacific donated No. 4014 to the Southern California chapter of the Railway and Locomotive Historical Society in Pomona, California, where it became one of the eight Big Boys preserved around the United States.[8][12]

Ownership transferEdit

 
Union Pacific SD70Ms Nos. 4014 and 4884 haul Big Boy No. 4014 over the Cajon Pass to Cheyenne, Wyoming, for restoration.[13][a]

In late 2012, Union Pacific officials announced that they would obtain a Big Boy locomotive, restore it to operating condition, and use it in excursion service.[16]

On July 23, 2013, the Southern California chapter of the Railway and Locomotive Historical Society agreed to transfer No. 4014 back to Union Pacific.[17][b]

On November 14, 2013, No. 4014 began its journey to the UP Steam Shop in Cheyenne.[20][21] It was pulled from its display site at the museum, on temporary track, to the adjacent parking lot.[20][21] On January 26, 2014, No. 4014 was pulled from the Los Angeles County Fairplex to the Covina station on Metrolink trackage by No. 1996, an SD70ACe diesel locomotive painted in Southern Pacific colors.[22] It presently arrived at UP's West Colton Yard in Bloomington, California,[23] where it sat on display until April 28, when it began its journey to Cheyenne.[13] After arriving at the Steam Shop's roundhouse on May 8,[24] No. 4014 sat largely idle for two years while the UP steam crew worked to overhaul No. 844.[25][26] The Steam Shop also used the time to expand and upgrade its facilities to accommodate a Big Boy.[27]

RestorationEdit

In August 2016, UP officials announced that restoration work on No. 4014 had begun under Heritage Fleet Operations director Ed Dickens.[28][29] No. 4014's driving wheels were sent to be repaired by the Strasburg Rail Road in Strasburg, Pennsylvania.[30][31] One of the most crucial tasks was converting the coal-burning locomotive to run on No. 5 fuel oil, which was performed by replacing the firebox grates with a fire pan and an oil burner.[32] The only other Big Boy so converted was No. 4005, which ran on oil from 1946 until it was converted back to coal in 1948 due to uneven heating in its large, single-burner firebox.[12]

In March 2018, it was reported that the process of putting the locomotive back together had begun;[32] ten months later, the locomotive's restoration was nearly finished.[33]

In December 2018, Union Pacific asked the Federal Railroad Administration (FRA) to exempt UP Nos. 4014, 844 and 3985 from federal Positive Train Control (PTC) requirements;[34] in February 2019, the FRA officials responded that such waivers were not needed.[35]

On February 6, 2019, No. 4014's boiler passed a hydrostatic test.[36][37] The locomotive was successfully test fired on April 9.[38] Around 9 p.m. on May 1, it moved under its own power for the first time in more than 59 years.[39] The following evening, the locomotive made its first test run: a round trip from Cheyenne to Nunn, Colorado.[40]

Excursion serviceEdit

Upon the completion of the restoration, No. 4014 joined the railroad's No. 844 in excursion service.[43][44] No. 4014 also became the world's largest operational steam locomotive, displacing No. 3985.[8][45]

No. 4014 made its first excursion run amid the celebrations marking 150 years since the completion of the First Transcontinental Railroad.[46][47] Following its May 4 christening at the Cheyenne Depot Museum, the locomotive — along with No. 844 — traveled to Ogden, Utah.[47][48] After making several brief stops in communities along the way,[48] No. 4014 arrived at the city's Union Station on May 8 for Ogden's Heritage Festival the following day.[49] It departed on May 12 and arrived back in Cheyenne on May 19.[50][51]

From July 8 to August 8, 2019, No. 4014 is on a Midwestern tour with stops planned in Illinois, Iowa, Minnesota, Nebraska, and Wisconsin.[52][53][54] The locomotive was displayed at Union Pacific's Home Plate in Omaha, Nebraska, on July 13-14;[55] it led a fundraising excursion to Boone, Iowa, to benefit the Union Pacific Railroad Museum on July 15.[56][57] The locomotive will also sit on display in St. Paul, Minnesota;[58] Duluth, Minnesota;[59] Altoona, Wisconsin; West Chicago, Illinois; and North Platte, Nebraska, exhibiting the "Experience the Union Pacific" rail car.[60]

IncidentsEdit

On May 16, 2019, two axles of No. 4014 derailed while entering the yard at Rawlins, Wyoming; it was returned to the rails within three hours.[61][62]

NotesEdit

  1. ^ On April 10, 2019, the diesel locomotive numbered 4014 will be redesignated as 4479 on the UP active locomotive roster, allowing the "Big Boy" to retain the number.[14][15]
  2. ^ On February 22, 2014, UP No. 3105 (née Missouri Pacific No. 6027), an EMD SD40-2C, UP insulated boxcar No. 453665, and bay window caboose UP No. 24567 (née Rock Island No. 17149) took No. 4014's place in the museum.[18][19]
