The primary ocean port in Senegal is in Dakar, the nations capital. It is one of the largest deep water ports along the West African coast. The total freight traffic averages about 10 million metric tons. The country, according to some sources, is well served by passenger trains and railroads. However, according to other sources, Senegal's trains, both freight and passenger, run very slow, at about 20 km/hour, due to poor condition. The highway system is extensive compared to West African standards, including paved roads reaching each corner of the country and all major towns. There are a total of 10 airports with paved runways. The main airport serves the Dakar region (and is also located in Dakar), called the Leopold Sedar Senghor International Airport. Other airports include the Saint-Louis Airport and the Richard Toll Airport. The airport in Dakar is the primary airport, and includes daily international flights, including flights to and from Johannesburg, Europe, and Atlanta.
