Wisner was platted in 1871 shortly before the railroad was extended to that point. It was named for Samuel P. Wisner, a railroad official for the Sioux City & Pacific Railroad. The Chicago & North Western ended railroad service in the spring of 1982, after years of declining freight traffic volumes & flooding damaged many sections of the track & abandonment was applied for. The tracks were removed a few years later.
