The line from Moshi to Arusha opened in 1930. 1931 census In 1931 a census established the population of Tanganyika at 5,022,640 natives, in addition to 32,398 Asians and 8,228 Europeans. Health and education initiatives Under British rule, efforts were undertaken to fight the Tsetse fly (a carrier of sleeping sickness), and to fight malaria and bilharziasis; more hospitals were built. In 1926, the colonial administration provided subsidies to schools run by missionaries, and at the same time established its authority to exercise supervision and to establish guidelines. Yet in 1935, the education budget for the entire country of Tanganyika amounted to only US$290,000, although it is unclear how much this represented at the time in terms of purchasing power parity.

The British government feared that these Axis country citizens would attempt to help the Axis forces and some of the Germans living in Dar es Salaam did attempt to flee the country but were stopped and later interned by Roald Dahl and a small group of Tanganyikan soldiers of the King's African Rifles.
