The suburb takes its name from Thomas Adams, who purchased a land grant of 54 acres of Crown land.
Adamstown officially became a suburb in 1885 and the first council was elected in 1886 with the council chambers being completed in 1892.[2] In 1938 Adamstown merged into other local council areas to become the areas of Greater Newcastle.[2]
Adamstown railway station, NSW, 1908
The Adamstown railway station opened in 1887 with the Newcastle–Gosford section of the Main North line.[3] The now closed branch line to Belmont formerly left the main line just south of Adamstown Station. The town also includes the beginning of the Fernleigh Track, a multi-use rail trail near Belmont. The project is a joint venture between Newcastle City Council and Lake Macquarie City Council and extends from Adamstown to Belmont over an approximate distance of 15.5 km (10 mi).
