Mills Tower Historic District encompasses the eastern portion of the Illinois
Central (IC) railroad yard, on the eastern edge of Iowa Falls. The small district
consists of several structures which date to the last two periods of Iowa railroad
history. Most alterations to the district have been to Mills Tower, the oldest
of the group. Mills Tower is a good example of the second generation utilitarian
support structures the IC built between the 1880s and 1930s to control traffic
along their lines. Mills Tower is the only interlocking tower left in Iowa, out
of nearly 70 previously in operation at various times and places.

| Mills Tower probably replaced the original Iowa Falls junction
in 1909, when the IC built a new river crossing and the new line made the older
junction obsolete. The actual date of construction is unknown. Unlike the first
tower, which "was doubtless of the 'Armstrong' variety" (having manually operated
levers) Mills Tower employed electrically operated levers. Mills governed the
switches in the IC yard west of the tower as well as the older Rock Island crossing
with the IC. In 1985 the Chicago Central & Pacific Railroad purchased the IC and
its employees refer to the tower as a "relic" and a "fossil." The first floor
was once used for offices and the second floor is the control room, as its many
windows attest. The key feature of the tower has always been the original electric
control board sitting in the middle of the room. A large train order signal stands
right next to the building, on the north side. Next to the tracks and just west
of the crossing diamond is a smaller metal pole with two slender metal hoops.
Train orders for the next segment of track were tied loosely to the hoops so the
engineer could grasp the papers with his hand while the train slowed for the crossing.
The Mills Tower Historic District is located on East Rocksylvania Ave.,
approximately 1/3 mile east of the old freight house and Illinois Central Depot.
There are no tours, as the Mills Tower and two contributing buildings are undergoing
a restoration; as is a caboose, restored to Illinois Central colors, now located
on the property. For information please call the Iowa Falls Historical Society
at 641-648-4603.
