Boonah railway station
In 1887, the railway line from Ipswich was extended to Blumbergville, with the name Boonah given to a rail siding located one stop before the terminus at the settlement of nearby Dugandan. The railway siding took its name from an Aboriginal word from the Yuggera and Yugumbir language groups meaning bloodwood tree (Corymbia gummifera) or Brigalow tree (Acacia harpophylla).
In 1888 Blumbergville was renamed as Boonah, and was served by Boonah railway station in Yeates Street. It was 34 miles 65 chains (56.0 km) from Ipswich at an elevation of 332 feet (101 m) [27.9969°S 152.6816°E].
