Union Pacific Historical Society Convention - Railroading Heritage of Midwest America Tour in Silvis 9/19/2025



by Chris Guenzler



The morning started with breakfast then two seminars were presented, the first was Rob Leachman's "Union Pacific 6900's - The end of an Era", followed by Mark Amfhar's Union Pacific-Rock Island Joint Traffic and Operations". That took us to late morning where a buffet lunch was offered, then the convention delegates boarded buses for the short drive to Silvis.

Railroading Heritage of Midwest America (RRHMA)

RRHMA is a non-profit organization whose mission is to promote public understanding of the history of railroading in the Midwest.

Our first view of restored Union Pacific DD40AX 6936, built by Electro-Motive Division in 1971. It is 98 feet long, consists of two 3,300 hp engines was built exclusively for the Union Pacific Railroad as the most powerful diesel-electric locomotive models built on a single frame. Nicknamed "Centennial" to commemorate the 100th anniversary of the Transcontinental Railroad, 6936 is the last operational DDA40X. In April 2022, Union Pacific officials announced that the company would donate the locomotive to RRHMA.

6936 was going to be leading excursions the next two days and many conventioneers purchased tickets for one or both of the trips, including Elizabeth and I.

Union Pacific 4-6-6-4 3985 was one of 105 4-6-6-4 Challenger type locomotives built by American Locomotive Company in 1943. It was included in the second order of the second version of Union Pacific’s 4-6-6-4 locomotives. The locomotive operated in fast freight and passenger service, pulling its last revenue train in 1957 before going into storage and eventual retirement in July 1962. UP 3985 was chosen for display at the Cheyenne passenger station and installed there in October 1974. A group of dedicated UP employees inspected the locomotive with the goal of eventual restoration to service. 3985 was removed from display in September 1979. The Challenger was returned to service in April 1981, with UP reinstating it to the active roster. On April 23, 1981 it double headed with UP 844 for the first time on a trip for the Grand Opening of the California State Railroad Museum. On June 16, 1982 it embarked on its very first solo trip to Pocatello, Idaho and return.

UP 3985 was converted from coal firing to oil firing in 1990 for ease of operation and to eliminate the tendency of starting lineside fires caused by hot embers from #3985’s stack. The locomotive burns readily-available diesel fuel which provides for much easier handling than coal and the disposal of the residual ash.

The final operation of the locomotive occurred during an extended tour of a portion of the Union Pacific system that ended on October 14, 2010. Union Pacific retired the locomotive from active service in February 2020.

3985 is only one of two in existence, the other is 3977 in North Platte, Nebraska. In April 2022, Union Pacific officials announced that the company would donate the locomotive to RRHMA, which plans to restore it to operating condition.

Union Pacific 2-10-2 5511, was built by the Baldwin Locomotive Works in 1929. The locomotive was Union Pacific class TTT-6, using UP’s system of the first letter of each digit in the wheel arrangement to designate the class. As a Two-Ten-Two locomotive the TTT designation was derived. UP 5511 employed the relatively rare Young valve gear which had been designed by Chicago and North Western employee O. W. Young and was first applied to a locomotive in 1915. The valve gear is noted for the elimination of the eccentric crank which reduced dynamic loading on the main driver.

Early in its career, UP 5511 was assigned to the Los Angeles and Salt Lake, a subsidiary of the Union Pacific and was assigned to hauling freight trains known as drag freights for their high tonnage and low speeds. 5511 was first stored serviceable starting in 1949 and operated as needed through 1956, including a stint as a stationary boiler at Ogden, UT. It was stored unserviceable at Green River, Wyoming, from 1958 through 1961, but was used in the filming of Union Pacific's publicity movie, Last of the Giants in 1958. The locomotive was pushed by a diesel located behind a string of freight cars with smoke created by burning old tires in the smokebox to create the illusion of a live locomotive.

UP 5511 was towed dead from Green River to Cheyenne in 1962, after its retirement and stored with other heritage equipment in the roundhouse there where it resided for sixty years until its donation to RRHMA-Silvis.

Rock Island ES44AC 513, built by General Electric in 2010 and better known as the "Rock Island heritage unit". Rather than being painted in standard IAIS phase V, it instead received a black and red paint scheme similar to what the Rock Island had on various freight EMD F units and Alco FAs. In addition, it bears the name "Rock Island" on the side and the RI "beaver pelt" logo on the nose. For reporting purposes, it carries a small IAIS on the cab side.

A planned stop on the way back to the hotel was at the former Rock Island station in Rock Island.









Chicago Rock Island and Pacific station designed by Charles S. Frost and built by John Volk in 1901, which represents the remnants of the first terminal built west of Chicago, which made Rock Island a pivotal location for the movement of people, commodities and raw materials. In 1845, civic leaders began to plan for the construction of a railway to Rock Island. Completing the first bridge over the Mississippi River, The Rock Island Lines sped the westward expansion of the United States.

This magnificent building served as the third Rock Island passenger depot. For many years, it was a hub of activity, with up to 32 arrivals and departures daily and 21 ticket agents working around the clock. As passenger trains gave way to air and highway travel, train depots became obsolete and the last scheduled passenger train left this station on May 31, 1978, after which the depot was closed "permanently" in April 1980. At the request of the City of Rock Island, the deteriorating depot was listed on the National Register of Historic Places in 1982.

Efforts to revive the classic structure failed until 1994, when the City of Rock Island purchased the property from the Iowa Interstate Railroad. The City restored the exterior in 1996 and replaced the clock tower. The entrance was returned to the southeast corner of the building. Adjacent to the depot was a deteriorated freight house, built with the same types of bricks and roof tiles as had been used on the depot. When it was demolished in 1997, its bricks and tiles were salvaged and used as necessary for replacements on the depot renovation.

In 1999, the City sold the property to Abbey Station LLC, which now operates this former depot as an elegant brunch and banquet facility.

The monument was erected to commemorate the 100th anniversary of the Chicago, Rock Island & Pacific Railroad Company, which completed building its rail to Rock Island on February 22, 1854. At the base of the left shaft is an image of the original Davenport depot, of 1856, the first depot of any railroad in Iowa, an historic claim that did not save it from the wrecking ball. Below the center shaft is the image of the first bridge across the Father of Waters, over which the first train between Rock Island and Davenport passed on April 21, 1856. And finally, at the base of the right pillar is the image of the first Rock Island Depot, constructed in 1854, the first railroad depot erected on the Mississippi in Illinois.
