Toowoomba began as a transport hub at Drayton for bullock wagons carrying wool and supplies. It grew due to its location at the base of the range, which provided access to the fertile Darling Downs lands and a watering hole. The railway line further increased Toowoomba's importance as a transport and commercial center, serving the agricultural industries of the region. Today, Toowoomba has developed into a major regional center providing educational, cultural, commercial and other services to the Darling Downs.
