According to the 2010 census, the village has a total area of 0.55 square miles (1.4 km2), all land.
Colfax was laid out on March 22 1880 by James E. Wood (22 October 1818 – October 1908). Anderson was born in Indiana and had come to McLean County about 1855 as State Missionary for the Christian Church. He stayed and became a farmer, a banker, and a lifelong promoter of Colfax. To locals, Anderson was affectionately known as “Uncle Billy.” The northeastern townships of the county were among the last to be served by railroads. After many false starts the Clinton, Bloomington, and Northwestern Railroad began making its way westward from Kankakee, Illinois. It was aided by contributions in cash and land for the right-of-way by many local farmers. Cropsey, Anchor, and Cooksville were all laid out at the same time as Colfax. The first train arrived in Colfax on 4 July 1880. For two years the track extended only from Kankakee to Colfax and a turntable was installed to send the trains back eastwards. Eventually the tracks ware completed to Bloomington. The Railroad soon became part of the Illinois Central system. Colfax is one of several communities in the United States named for Grant's Vice President Schuyler Colfax. Others include Colfax, California; Colfax, Indiana; Colfax, Louisiana; Colfax, North Carolina and Colfax, Washington.
Original design and early growth 
The Original Town of Colfax was a rectangle on the north side of the tracks. There were twelve blocks, each with eight or sixteen small lots, and an additional four blocks, each with a single larger lot, were located along the western edge of the Original Town., for a total of one hundred lots. These faced a widened area of railroad land, which ran the full length of the Original Town. No other public spaces were designated, but Main Street, which ran parallel to the tracks and one block to the north, was wider than the other streets. The depot was on the north side of the tracks and the early elevator, lumber yard and stock yard were on the south side. William Rinker erected the first store, which sold groceries. Another grocery store, Wilson and Santee, followed. The third store was a somewhat larger two-story structure built by D.A. Green, who had moved his operation into Colfax from Potosi near the McLean County–Livingston County border; Green sold groceries, dry goods and drugs.
First coal mines 
In 1886 a company was formed to open the first of two coal mines at Colfax. The first to be opened was the shaft just west of town. Frank Seymour and Sons were paid fourteen dollars a foot to sink the shaft. They encountered problems with water, with cave ins and were soon slowed by the need to blast their way through limestone layers before reaching the coal seems. The railroad was unable to bring in sufficient shoring for the shaft and additional timber had to be hauled in by wagon. At 140 feet (43 m) they struck a narrow vein of coal, but excavators had to go down to 392 feet (119 m) before finding a productive 5-foot-thick (1.7 m) seam of coal. Miners were brought in, and the first coal was taken in June 1888. Financial troubles and rapid changes of ownership soon followed. 1⁄2 The organization of a company to open a second shaft, this one east of town, shaft began in December 1891, but it was June 1894 before digging could begin.
Problems with the mines 
The east shaft encountered great difficulties with water and with layers of quicksand. After many delays and extensive pumping, coal was found in 1895, but trouble with financing delayed production for two years. The 200 miners who flooded into Colfax encountered an acute shortage of housing, which was not solved until a large number of small miner’s cottages could be built: a few of these may still be found in Colfax. Financial troubles quickly mounted In May 1892 the east shaft had to be sold at auction. In 1901 and 1902 almost 60,000 tons of coal were being taken out of the mines, but increased difficulty with finances soon reduced production. Once the mines were opened, unions were organized and strikes followed. Mining at Colfax proved to be a deadly business; between 1889 and 1902 eleven miners died, most of them crushed by falling rock. The west shaft produced most of the coal, but was closed in 1904. This mine remained idle for many years until being briefly re-opened as a cooperative venture between 1921 and 1924. Eventually the abandoned shaft became a rubbish dump and was eventually filled.
Growth of the town 
Once established, Colfax grew rapidly. In 1892 a tile factory was built in the northeast corner of town; as was often the case in central Illinois, the former tile factory grounds eventually became a small park. A cigar factory was built. About the same time, a small factory for the manufacture of tin cans started production. By 1888 Colfax had a newspaper, the Colfax Leader. Electric lights came in 1895. Four churches began soon after the town was founded: Christian, Methodist, and Presbyterian, and Roman Catholic. William H. Anderson, who raised Standard Bred and Road Bred horses, had a half-mile horse track just east of town. After the mines closed, Colfax settled into a quieter life as the commercial hub of a prosperous grain-growing area. However, eastern McLean County has been an area of little population growth and the population of Colfax, which peaked in 1900, had dropped fourteen percent by 2000.
