Transport in the Republic of the Congo includes land, air and water transport. The country’s rail system was built by forced laborers during the 1930s and largely remains in operation.Train travel is possible to Matadi from Kinshasa, as well as from Lumbumbashi to Ilebo or Kalemie through Kabalo. The Great Lakes railway runs between Ubundu and Kisangani, passing Stanley and Boyoma Falls along the way. Train schedules are unreliable though, as service may be disrupted for lack of fuel or political incidents. Principal trains have dining cars and couchettes, but are still not air-conditioned.Minibuses operate in big cities like Kinshasa and are also referred to as taxis. The fares often vary, and a premium may be added at will. Another type of taxi in the Congo is the small bus; to hail it, you simply need to point to the direction where you want to go. If the taxi has space and is going that way, it will stop. Foreigners might have difficulty using these hand signals and getting familiar with the routes, and it can get uncomfortable sitting in a cramped vehicle, which is why a tour package is a good idea as drivers do not speak English.
