Braunschweig was one of the centres of the industrialization in Northern Germany. During the 19th and early 20th century the canning and railroad industries and the sugar production were of great importance for Braunschweig's economy, but eventually other branches such as the automotive industry became more important, while especially the canning industry began to vanish from the city after the end of World War II. The defunct truck and bus manufacturer Büssing was headquartered in Braunschweig. Current factories in the city include Volkswagen, Siemens, Bombardier Transportation, and Bosch.
