Speaking of Mombasa City, its development indeed greatly exceeded Ernst's expectations, though upon reflection, it seems reasonable.
Mombasa's economic development primarily relies on the Northern Railway, while the western part of northern East Africa does not have an outlet to the sea; it borders the colonies of countries like Belgium and France.
This means that the entire Northern Railway is top-heavy, with its foreign trade almost entirely dependent on Mombasa, a single seaport city.
In contrast, Dar es Salaam City, located on the Central Railway, faces much more competition. Bajamojo City and New Hamburg Port City can also share in the trade, especially as the East African railway network becomes increasingly complete. Bela Port, Cabinda Port, Benguela Port, Luanda Port, and others can bypass Dar es Salaam City.
