[4][5] The town was a station stop on the now-abandoned transcontinental main line of the Chicago, Milwaukee, St. Paul and Pacific Railroad ("the Milwaukee Road"), and was the site of one of the substations of the railroad's electrification project.

Two Dot was founded in 1900 as a station on the Montana Railroad, local predecessor to the Milwaukee Road.

The name of the town's post office was officially changed from Twodot to Two Dot in 1999.

[9] In 1983 Hank Williams Jr. immortalized Two Dot in his Strong Stuff album with the song "Twodot, Montana".
