MARENGO — The Union Pacific #4014 Big Boy, the world’s largest steam locomotive, drew crowds lined several deep along the tracks the first week of September during a whistle-stop visit beside the historic 1894 train depot at Ninth Street in Belle Plaine.
The 132-foot leviathan, including its oil and water tenders and complement of baggage, coach, dome, sleeper cars and rolling museum car, announced its arrival by whistle and rolled into position for a photo session of about twenty minutes as admirers stood in pouring rain to see, feel, and hear the power of a bygone technology and era.
Belching plumes of black smoke and shrouding itself in a cloud of billowing steam, the one-million pound engine added thunder to accompany the patter of raindrops.
Despite the dousing from above, the enthusiasm of rail fans of all ages was not dampened, and they remained for the duration of the train’s brief respite on the Iowa/Benton County border.
Some got a steam bath to go with the showers as the engine released excess steam pulling in and out of the station.
With the locomotive remaining for only a few minutes and security personnel patrolling the tracks to keep the public at least 25 feet away from the train at all times, it was difficult to get an up-close and personal look at the towering five-and-a-half-foot wheels, drive rods, pistons and steam lines that enable the inimitable engine to roar to life.
To provide an intimate view of this and other locomotives, the Iowa County Historical Society is offering an opportunity for such an up-close viewing of the complex assemblage of iron and steel that shapes the train in a new exhibition of railroad history that includes a four-foot scale model of the Big Boy.
Replicating the engine in precise detail, each piece, no matter how minuscule, has been rebuilt with one quarter inch equaling a full foot all the way down to the ringing bell at the lead and the model number hand painted on the engineer’s cabin.
Similar models of the Union Pacific 4-12-2, with even more wheels than the Big Boy, will be displayed along with the line’s legendary Challenger locomotives and the revolutionary M-10,000 series streamlined trains that transformed the way America traveled by rail.
It was thrilling to experience the sight, sound and feel of the 4014 in Belle Plaine, but for many, too brief and too distant. With this display, the public can come nose to nose with the engines and inspect the intricate details they didn’t get to see while in the crowds and across the tracks in the rain.
The Chicago Rock Island and Pacific Railroad is also included in the assembly, with exquisitely reproduced 1:48th replicas of the iconic Rock Island Rocket passenger trains that whisked hundreds of thousands of rail patrons across Iowa for nearly 50 years.
Steam locomotives of the Rock Island line from the era of the Big Boys are also demonstrated in the exhibit along with artifacts of the rail line, all displayed in the historic 1861 CRI & P depot that is part of the Pioneer Heritage Museum in Marengo.
The depot was moved from Victor to be a tavern for many years before being brought to Marengo and renovated to retain its original charm.
Renowned trains and equipment of other lines are also featured in the exhibition highlighting the sleek Hiawathas that crossed the state in their signature orange and red rolling stock of the Milwaukee Railroad and the fabled Pioneer Zephyrs of the Burlington line that flashed their silvery glow across Hawkeye country at nearly 100 miles per hour.
These stand in distinct contrast beside the dark black livery of the modern locomotives of the Iowa Interstate Railroad, which took over the tracks from the Rock Island line in the 1980s and continues freight delivery throughout the state.
I will deliver the final installment of the historical society’s 2024 lecture series at the Iowa County Historical Museum complex in Marengo.
The lecture and question and answer roundtable is titled “The Grip of the CRIP: The Legacy of the Rock Island Railroad in Iowa” and is scheduled for 2 p.m. Sunday Oct. 6 at the museum’s renovated rail station.
The lecture is an opportunity to learn the history of the first railroad to cross the Mississippi River into Iowa on the 165th anniversary of the beginning of construction of the line to Marengo, Des Moines and points west and to see the most iconic trains that have steamed or whistled across Iowa over the last century and a half, making the state the railroad crossroads of the nation.
This lecture and exhibit is free and open to all. Contact (319) 642-7018 for more information.
