To bring these agricultural products to market, beginning in 1888, the Usambara Railway was built from Tanga to Moshi. The Central Railroad covered and linked Dar es Salaam, Morogoro, Tabora, and Kigoma. The final link to the eastern shore of Lake Tanganyika was completed in July 1914 and was cause for a huge and festive celebration in the capital with an agricultural fair and trade exhibition. Harbor facilities were built or improved with electrical cranes, with rail access and warehouses. Wharves were remodeled at Tanga, Bagamoyo, and Lindi. In 1912, Dar es Salaam and Tanga received 356 freighters and passenger steamers and over 1,000 coastal ships and local trading-vessels. Dar es Salaam became the showcase city of all of tropical Africa. By 1914, Dar es Salaam and the surrounding province had a population of 166,000, among them 1,000 Germans. In all of the GEA, there were 3,579 Germans.
