This is an exploration of the Union Pacific's Sioux City Sub from California Jct., IA to Sioux City IA. The Sgt Bluff Industrial and Dakota City Industrial leads will also be looked at. Current and historical images will be used along with a
map of the Sioux City Sub
History Lesson
The line from California Jct. to Sioux City was originally built in the fall of 1867 and spring of 1968 by the Sioux City and Pacific Railroad with funding from the Cedar Rapids and Missouri River Railroad (CNW leased company). In 1864 the UP was released from its obligation to build a branch to Sioux City as required by the Pacific Railway Act of 1862. The SC&P completed what would have been a UP branch line had this obligation not been lifted, though the UP branch would not have followed the current route.
Current State
Since the merger with the CNW in 1995 the UP has operated the Sioux City sub and brought some much needed improvements to this line. Rail, ties, ballast and a new siding are the most obvious changes to the line. Unfortunately these improvements also resulted in the loss of the lower quadrant semaphores with the standard UP Darth Vader tricolor signals for the ABS system.

California Jct., IA
The Sioux City sub begins at California Jct for northbound/eastbound trains and ends there for southbound/westbound trains.
Northbound trains off the Omaha sub will call the Sioux City branch dispatcher at south Missouri Valley for permission to enter the branch. While the crew awaits permission from DS 47, DS 20 is contacted to gain permission to cross from the Omaha Sub to the Blair Sub to access the wye at California Jct. This complicated process occurs in the distance of less than 10 miles and often results in northbound trains holding at Missouri Valley until a slot is open on the Blair sub to proceed.

Once permission is given by DS 47 on the Sioux City sub it will typically be from from California Jct to either Mondamin or Blencoe, IA. The sub is TWC and meets occur at these two locations along with Salix, IA. Since this is a TWC line listening to the scanner traffic and noting how far a train has permission to proceed to will give a good indication of where a meet will occur.
Southbound trains off the Sioux City Sub are held just north of California Jct. before proceeding either west on the Blair Sub or east on the Blair Sub to the Omaha sub.

Mondamin, IA
Mondamin has the first siding north of California Jct. Of the sidings along the sub this is the smallest at just over 5300' long. Mondamin was once a junction with the CNW Boyer Valley line. This line was removed in the 50's and 60's in sections heading east to Wall Lake, IA. This junction configuration resulted in the Mondamin siding taking a jaunt to the east around where the old yard was located before returning to the main north of Mondamin.
The local coop still has a load out track connected to the siding, though no cars have been observed at this elevator for some time.

A loaded coaler crosses over the Little Sioux River just north of River Sioux, IA. |
Blencoe, IA.
Blencoe has the longest siding between Sioux City and California Jct. Most meets are staged at Blencoe due to its length.
Blencoe does have one customer as the coop will receive inbound cars of fertilizer and will ship an occasional grain load out.The coop is typically switched by the MSXCB as the switch is south facing.

The MVPNP meets a coaler under the coop elevators in Blencoe, IA. |
Onawa, IA
Onawa was once the junction with the CNW Maple River line. This line connected on the south side of Onawa and the old ROW can be seen in places.The CNW depot was moved a number of years ago and now rests in the city park on the north side of Onawa. This is one of only two depots still standing from the Sioux City Sub.
Onawa has one customer left on the UP. Northern Ag Services, where loads of salvaged grain are shipped from its facility. This is also the location of a rare Vulcan end cab switcher.

Sloan, IA.
Sloan, IA is home to the only shuttle loader on the line. Western Iowa Coop loads 110 car grain trains using an ex SBD GP16 that is typically locked away in the engine house in Sloan.
There is also a siding at Sloan that is typically used for MOW storage.
Salix, IA
A new siding was built between Salix and Sgt Bluff, IA in the late 90's to replace the Sgt Bluff siding. This siding is used to facilitate meets with coal trains entering or exiting the Sgt Bluff Industrial lead and road trains out of or into Sioux City.

Heading south between Sgt Bluff and Salix a loaded ETOH train makes track speed. |
Sgt Bluff, IA
Sgt Bluff was once connected to the Moville Extension that headed east to Moville, IA and connected with the Maple River line further east. This line was abandoned in the 50's in sections heading east from Sgt Bluff. Little ofthe ROW can be seen today in Sgt Bluff due to urban sprawl.
Sgt Bluff is also the location of the Sgt Bluff Industrial lead and its many industries and the four coal power plants at Pt. Neal. This important line is responsible for enough car loads to fill a daily train between Sioux City and Council Bluffs, IA
 |
A BN powered coal train passes the CNW depot at Sgt Bluff, IA. |
The biggest customers on the lead are MidAmerica energy and AGP. MidAmerica has 4 power generation plants at Port Neal landing with the largest of these being Pt Neal #4. At any given time a coal train can be found unloading at either the Pt Neal #4 loop or the Pt Neal 1,2 &3 loop. These trains are exclusively powered by UP units as the BNSF no longer has the contract to delivery coal to these plants.
 |
EMNPA passes through Sgt Bluff, IA |
AGP is located next door to Pt. Neal #4 and has an extensive operation. Unit trains of soybeans are often unloaded here and soy meal and refined soybean oil are shipped out. The AGP plant employes two switchers of its own for in plant movements. An AGP painted B23-7 and a GP9 can be seen on the south side of the plant moving cars.
CF Industries is another large shipper. The former Terra Chemical plant is located to the north of the Pt Neal 1,2, & 3 complex. This facility is not longer accessible due to increased security measures in place. The plant is switched by a GE 65T center cab switcher.
 |
Just south of Sgt Bluff, IA the MVPNP is heading for California Jct and points west. |
Under the I-29 overpass the Sgt Bluff Industrial lead splits with a line heading south to Pt. Neal and another heading north to the Big Soo terminal area. Along the line to the Big Soo terminal are a number of important shippers.
Compressed Steel moved its operations to the industrial area south of the Big Soo terminal after the city requested it be moved out of downtown. A number of gondolas of scrap are shipped out daily.
Cloverleaf Cold Storage ships ARMN refers of boxed pork products from the warehouse in this industrial area. Shipments of boxed pork and beef have been increasing since the UP merger.
The Big Soo terminal was once an important barge transload terminal. Today it serves as a fertilizer transload facility since river barges no longer travel to Sioux City.
Sioux City, IA
Sioux City is a shadow of its former self. The once busy yard is now just a shell with a number of tracks having been removed and the locomotive shop and servicing facilities removed. With the loss of a number of tracks this yard is typically packed. The MCBVP/MVPNP and MKCVP trains typically make setouts and pickups that are greater than 50 cars.
 |
EMNPA heads out of Sioux City with UP power during a cold winter day in 1982. |
At the north end of the UP yard the UP joins the CN mailine to LeMars, IA. This switch marks the end/begining of the Sioux City Sub.
 |
A southbound UP grain train holds on the CN main at the switch marking the beginning of the Sioux City Sub for a new crew to board. |
 |
20+ years earlier a CNW grain train holds at the switch for a new crew. |
In the city proper there are very few customers. The largest is Tyson Cold Storage who ships ARMN refers of boxed beefs on a daily basis. Additional customer activity is interchange with the CN, DAIR and the BNSF railroads.
DAIR interchanges complete ballast trains with the UP along with Georgetown gravel and rock trains.BNSF and CN interchange cars with the UP with the most interchange occurring with the BNSF. As a curious note the DM&E and Dakota Southern railroad has the ability to interchange with UP at Sioux City as part of the state of South Dakota's agreement with the BNSF that allowed it to purchase of the state owned lines. So far the Dakota Southern and DM&E have not exercised these rights.

Dakota City Industrial lead is the remnants of the CStPM&O mainline to Omaha, Norfolk and the NE Nebraska branch lines. This line was severed to Omaha in the 30's with Omaha freights using the Sioux City Sub to California Jct and then the Blair sub to Blair to regain access to the Omaha tracks to N. Omaha. In 1977 the remaining track from Norfolk, NE to Dakota City NE was abandoned and removed.
 |
CNW 4170 takes the dip at Ferry, NE as it leaves the BN main to its own track. |
During the CNW years this track age suffered from deferred maintenance and was a 5 mph roller coaster ride from Ferry to Dakota City. In the mid 90's an Oats processing plant opened on the CNW track and the line was repaired to allow 286000lb cars and 10 mph speeds. The UP has further upgraded this line to but still maintains the speed at 10 mph .
Tyson foods is the largest shipper on this line after Vittera Grain. Roughly 10-15 tank cars of tallow and a couple of cover hoppers of recovered grain are shipped out daily.
