History
Winfield was laid out in 1852. It experienced a growth with the arrival of the Burlington and Northwestern Railway in late 1876, connecting the town with Burlington. The line was extended along the east side of town and reached Washington at the start of 1880, and in 1881, the Burlington and Western Railway was incorporated to build a line from Winfield to Oskaloosa. The new line branched from the Burlington and Northwestern just north of town reached Coppock the spring of 1882 and Oskaloosa in late 1883. These were 3 ft gauge railways.
In 1882, the Chicago, Burlington and Pacific constructed a rail line west from a railroad ferry crossing of the Mississippi River at Oakville, Iowa to Oskaloosa. This line passed Winfield along the south border of Winfield, and it largely paralleled the Burlington and Western to Oskaloosa, Iowa. The line was sold to the Central Iowa Railway as soon as it was built, and that line became the Iowa Central Railway a few years later.
Winfield was the hometown of the sports reporter Bill Bryson Sr.
