Union Pacific 4014 is a four-cylinder articulated 4-8-8-4 Big Boy-class steam locomotive owned and operated by the Union Pacific Railroad. Built in November 1941 by the American Locomotive Company (ALCO) of Schenectady, New York, the locomotive is the only operating Big Boy of the eight that remain in existence.

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 at their Steam Shop in Cheyenne, Wyoming. On May 1, 2019, No. 4014 ran under its own power for the first time in over fifty-nine years, becoming the largest operational steam locomotive in the world. It now operates in excursion service.

Design[edit]

The Big Boy class was developed by Union Pacific and ALCO to overcome problems with its 4-6-6-4 Challenger-class locomotives.[4] UP determined that its goals for the new class could be achieved by making several changes to the existing Challenger design, including 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.[4] 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.[5] Peak horsepower was reached around 35 mph (56 km/h); optimal tractive effort was reached around 10 mph (16 km/h).[5]

History[edit]

Revenue service and retirement[edit]

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

UP No. 4014 was part of the first group of 20 Big Boys, classified as 4884-1.[3] In December 1941, ALCO delivered No. 4014 to Union Pacific, which placed it in revenue service.[1] 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.[6]

No. 4014 completed its final revenue run on July 21, 1959, just hours before the last revenue run by any Big Boy. 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.[5] All of the Big Boys were retired by 1962, their duties assumed by diesel locomotives and gas turbine-electric locomotives (GTELs).[1][7] Union Pacific donated it 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.[1][5]

Ownership transfer[edit]

Union Pacific SD70Ms Nos. 4014 and 4884 haul Big Boy No. 4014 over Cajon Pass to Cheyenne, Wyoming, for restoration.[8][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.[10]

On July 23, 2013, the Southern California chapter of the Railway and Locomotive Historical Society agreed to transfer No. 4014 back to Union Pacific.[11][b]

On November 14, 2013, No. 4014 was moved from its home at the museum, on temporary track, to the adjacent parking lot in preparation for its move to the restoration facilities in Wyoming.[14] On January 26, 2014, No. 4014 was pulled out of the Los Angeles County Fairplex to begin its journey to the UP Steam Shop in Cheyenne.[15]

The locomotive arrived at Cheyenne on May 8, then sat largely idle for two years while the UP steam crew focused on the successful restoration of No. 844.[16][17]

Restoration[edit]

In late July 2016, UP officials announced that restoration work on No. 4014 had begun under Heritage Fleet Operations director Ed Dickens.[17][18] No. 4014's driving wheels were sent to be repaired by the Strasburg Rail Road in Strasburg, Pennsylvania.[19][20] To convert the coal-burning locomotive to run on No. 5 fuel oil, the firebox grates were replaced with a fire pan and an oil burner.[5][21] In March 2018, it was reported that the process of putting the locomotive back together had begun;[21] ten months later, the locomotive's restoration was nearly finished.[22]

No. 4014 was successfully test fired on April 9, 2019, and on May 1 at around 9 p.m., it finally moved under its own power for the first time in over 59 years.[23][24] The following day, the locomotive left Cheyenne on its first test run to Nunn, Colorado and return.[25]

Excursion service[edit]

Upon the completion of the restoration, No. 4014 joined the railroad's No. 844 and No. 3985 in excursion service.[5][26][27] No. 4014 also became the world's largest operational steam locomotive, displacing No. 3985, which was the largest operational steam locomotive until it was taken out of service in 2010 due to mechanical problems.[5][26]

No. 4014 made its first excursion run amid the celebrations marking 150 years since the completion of the First Transcontinental Railroad.[28][29] Following its May 4 christening at the Cheyenne Depot Museum, the locomotive — along with No. 844 — traveled to Ogden, Utah, making several brief stops in communities along the way.[28][30] No. 4014 arrived at the city's Union Station on May 9, and departed on May 12.[31][32] It derailed on May 16 while entering the yard at Rawlins, Wyoming; it took three hours to get the locomotive back on the rails.[33] It then continued its journey the next day, and finally arrived back in Cheyenne on May 19.[34]

Notes[edit]

  1. ^ The diesel locomotive numbered 4014 will be redesignated as 4479 on the UP active locomotive roster, allowing the "Big Boy" to retain the number.[9]
  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.[12][13]
