Overview

Like most other railroads in the United States, Union Pacific has always separated its operations into administrative units for management purposes. The earliest were the Divisions and Subdivisions. As the railroad expanded into most of the western states in the 1880s and 1890s, the divisions became part of larger Districts. Districts remained as an administrative designation until the merger era of the 1980s and 1990s.

1936
The districts were fully formalized as part of the 1936 "Unification" and lease of the railroad's three largest subsidiaries.

1983
A new Western District (former WP) was added in 1983, alongside the existing Eastern, Northwestern and South-Central Districts that were created in 1936.

1986
Regions replaced Districts in 1986, to consolidate UP and former MP operations. Regions were eliminated in 1987 when Service Units were adopted. Regions were re-established in 1991 to add a management layer between 21 service units, and headquarters in Omaha.

1998
Timetable Areas were adopted in 1998 as part of the overall reorganization to better integrate Southern Pacific into the Union Pacific network.

The relationship between service units and timetable areas has regularly changed to match ongoing operational changes to match business advances and declines, and to match day-to-day operations with day-to-day maintenance requirements. Traffic fluctuates over the span of years and operations need to be adjusted to make best use of resources, including personnel, equipment and physical parts of the railroad. These changes mean that the relationship between timetable areas and service units has changed regularly, and continues to be ongoing and seemingly constant.

As yet no reference has been found that shows a direct correlation between timetable areas and service units, except in brief comments and special rules.

Timetable Areas

The use of Areas as part of the employee timetables came in 1998 following the control of Southern Pacific in September 1996, and the severe service disruptions that began in July 1997. Solutions to the massive service disruptions took months of concentrated and focused activity by employees down on the line, and by managers at all levels. In spring 1998 planning began for a complete reorganization of all of the railroad's administrative units, and the completed plans were formally announced in August. The entire railroad was covered in a new series of 20 timetables that were issued on October 25, 1998, covering the 20 newly designated areas. The use of timetable areas remains in use today (2023), with a few changes in areas and area boundaries, along with the use of service units and larger regions as the method of managing operations on Union Pacific.

The change to Areas was an effort to decentralize decision making. Maury Klein wrote, "to move more decision-making authority out of Omaha. Employees wanted more latitude to make decisions based on local conditions that they knew better than did Omaha."

Maury Klein continues...

In the spring of 1998 he [Davidson] asked Duffy to head a task force to determine what the newly merged system should look like. The team concluded that neither a quick fix nor incremental changes would work; what was needed was nothing less than a transformation. By August Duffy's team had come up with plans for a revamped organization that fit this need.

Duffy's plan divided the organization into three regions with a vice president in charge of each one. Steve Barkley, based in Houston, took charge of the Southern Region, Mike Kelly (Omaha) of the Northern Region, and Jeff Verhaal (Roseville) of the Western Region. The dispatchers remained at the HDC but were realigned to fit the new regional configuration.

First announced in August 1998, the new structure contained twenty-two operating units headed by superintendents. Support functions such as engineering and mechanical were also decentralized and reported to the regional head to enable quicker responses to local operating needs. The key to the arrangement lay in giving the regions considerable authority and responsibility while requiring them to work within a centralized plan.

1936 - Districts

The districts were fully formalized as part of the 1936 "Unification" and lease of the railroad's three largest subsidiaries.

(Read more about the 1936 Union Pacific "Unification")

Eastern District

The original Omaha to Ogden Overland Route mainline became the Eastern District, which also included lines in Kansas and Colorado.

Central District

The Oregon Short Line from Granger, Wyoming to Huntington, Oregon, became the Central District, which included the line into Montana.

Northwestern District

The Oregon-Washington Railroad and Navigation portion from Huntington to Portland, Oregon, and on to Seattle, Washington, became the Northwestern District.

Southwestern District

The Los Angeles and Salt Lake portion from Salt Lake City to Los Angeles became the Southwestern District.

In 1937 the Central District (OSL) and the Southwestern District (LA&SL) were consolidated and rearranged to become the South-Central District.

1983 - Districts and Divisions

The districts created in 1936 and 1937 remained in place until Union Pacific's control of Western Pacific and Missouri Pacific in 1983.

The merger of Union Pacific, Western Pacific and Missouri Pacific was approved on December 22, 1982, and took effect on January 1, 1983. Missouri Pacific remained as a separate operation until 1987, but Western Pacific was integrated into the existing Union Pacific network as soon as the details were worked out. The first combined employee timetable was issued on June 12, 1983 (with its famous pink cover) and the former Western Pacific was shown as the newly created Western District. The new district was divided into the Western Division and the Eastern Division, with Flanigan, Nevada, as the point of separation.

(The last WP-SN-TS employee timetable was System #10, dated October 31, 1982; divisions and subdivisions only)

(Read more about the UP-WP-MP merger)

The existing UP Eastern District, Northwestern District, and South-Central District remained unchanged; Western District added.

1986 - Regions and Divisions

The designation of Regions as a replacement to the Districts came in 1986. This was on both the Union Pacific and the Missouri Pacific, which was being operated separately. The change was in preparation to the integration of Missouri Pacific into the Union Pacific network.

The change from Districts to Regions was published in System Timetable No. 4, dated October 26, 1986, which was also the first to include all of the Missouri Pacific lines as part of the Union Pacific System.

(The last MP timetable, System No. 2, was dated October 27, 1985, and included divisions and districts, but not regions.)

1988 - Divisions, Subdivisions and Service Units

The designation of Service Units was yet another way of managing larger parts of Union Pacific. As already mentioned, divisions and subdivisions were the favored method of dividing the railroad into administrative units starting in the earliest days of the railroad as early as the 1870s. During the merger era that began in 1982, the complexities of merging two large successful railroads delayed the integration of the Missouri Pacific as part of Union Pacific. The operating departments were consolidated on January 1, 1986, and the final formal merger was completed 11 years later on January 1, 1997.

The integration of Missouri Pacific and Union Pacific following the consolidation of operating departments in 1986, brought the use of Service Units alongside the existing divisions. The first employee timetable to show service units was System Timetable No. 6, issued on May 15, 1988.

Although the concept of service units to replace divisions was adopted in 1987, as late as the October 1995 issue (the last issue before the SP merger), the timetables continued using the combined phrase "Division Service Units."

Maury Klein described the adoption of Service Units:

"We went from Divisions to Service Units. We flattened the organization"

The existing three regions (sic: districts) each had a general manager with an assistant and four superintendents reporting to him. Each region also had a full-blown staff that mirrored Omaha's headquarters staff. Each superintendent had his own little bureaucracy as well. Every decision, large or small, had to climb the ladder and that process could take forever.

The new plan created a centralized organization in Omaha presiding over thirty decentralized superintendents who ran the day-to-day operations. In place of the traditional mechanical, engineering, and transportation departments five new groups were formed: Service Operations, Service Resources (which included dispatching and the mechanical shops), Engineering Services, Contractor Services, and Service Design.

Walsh unveiled this new plan at a leadership conference in July 1987. As he explained it, the new organization centralized key policy and support functions while decentralizing key operating and implementation responsibility.

Beginning on September 17, 1987, with two service units, the changeover proceeded at a rate of two to four service units a week. By December 5 all three regions and twelve former divisions had been replaced by the thirty service units.

But within a year, those 30 service units were reduced to 24, and the three general superintendents were re-instated.

1991 - Divisions, Subdivisions and Service Units

Regions had been eliminated in 1987 when service units were adopted. Regions were re-established in 1991 as a way to improve communication and decision making between the service units and headquarters in Omaha. The changes in 1988 that integrated the Missouri Pacific as part of the Union Pacific network had created 30 service units across the entire railroad. Managers soon found that headquarters was receiving too much local and day-to-day information to fulfill its larger strategic role, so a layer of management was added in the form of three Regions. Each of the three regions had its own General Superintendent and each region took over the administration of seven of the 21 service units (reduced from the original 30 service units). This change in 1991 also integrated the Missouri-Kansas-Texas railroad which Union Pacific had controlled since August 1988, and which was merged into Missouri Pacific in December 1989, to became part of the single Union Pacific network.

Four Regions:

January 17, 1997
From "Update Line", published by the Union Pacific Communications Department, dated January 16, 1997.

Union Pacific has recently changed the boundaries, and in a couple cases, the names of the four regions comprising the system.

The old Midwest Region and part of the Western Region is now called the Northern region. Beginning at Ogden, UT and McCammon, ID, it extends east covering the states of WY, CO, NE, IA, MN, WI and northern IL.

The old Eastern Region is now called the Central Region covering southern IL, MO, northern AR, KS, OK, west TX, NM and AZ.

The Southern Region is track south of Little Rock, AR and Ft. Worth, TX to the Gulf of Mexico and west to Alpine, TX.

The Western Region consists of all states from UT and ID to the West Coast.
