In 1926, work began on the nearby Milson railway deviation which was to take the main trunk line out of the city centre. Earlier in the decade, the Railways Department was granted their own housing programme to combat problems in housing its workers. To service the construction of the Milson deviation, the department erected a railway settlement in the area, calling it Milson. Some 70 railway houses were built. Milson Primary School and a community centre were built to serve the workers and their families. many of these houses were sold following reforms of the railways in the late 20th century. About 60 houses remain today.

Much of the rest of the suburb was constructed after the 1950s.

Milson, and Milson Line (a main street in the suburb), are named after a historic local land owner
