The Congo-Ocean Railway (CFCO) is a public institution in the Republic of Congo that operates a railway network of 885 km, with a gauge of 1,067 mm. There are three sections: the Congo-Ocean line, which connects the port of Pointe-Noire, on the Atlantic Ocean, to Brazzaville, built from 1921 to 1934 (512 km)1, the section from Mont-Bello to Mbinda, built from 1959 to 1962 (285 km) and the line from Bilinga to Dolisie, a realignment built from 1976 to 1985 (91 km). Serge, my former colleague in Congo, is waiting for me at the airport. We are going to take a trip around the country together for two weeks. I rented a Toyota Hilux, 4-wheel drive, to reach the north of the country, on the border with Cameroon, from Pointe-Noire. The very beautiful and imposing Pointe-Noire railway station. This station was opened in 1934 and serves the capital Brazzaville. The offices of Océan Express, where my professional adventure in Congo began in 2014. At the time, my accommodation was on the first floor, and the offices on the ground floor. Serge, my first recruit in 2014, who I met again 9 years later to set off to explore the country. Here is Rosine, my housekeeper at the time, still faithful to her post. To finish with Pointe-Noire, the offices of Ponticelli Congo. Access to the industrial zone of Pointe-Noire is still chaotic. A stop at the Casino store in Pointe-Noire to stock up on cereals, canned corn and ravioli, so as not to starve to death in the hinterland... And off we go to point zero on national road 1, towards Brazzaville. Here is the 0 kilometer marker at the exit of Pointe-Noire on the national road. Brazzaville is some 500 km further east. For the first day in Congo, I opted for a short stage of only about fifty kilometers. The crossing of the Mayombé massif is a very accident-prone route, as you can see. We arrived safely in the small village of Les Saras, located on the Pointe-Noire / Brazzaville railway line. We spent our first night in a cabin perched on top of a baobab tree, overlooking the village. I would have liked to film more inside the station, but a policeman asked me for a mission order authorizing me to do so. The Brasco and BraLico breweries are very prosperous in Congo. The port of Yoro on the Congo River, with pirogues and whalers moored there. had to be ... a couple to be able to go there ... The memorial in honor of Pierre Savorgnan De Brazza (1852-1905), in Brazzaville. The Republic of Congo, also called Congo-Brazzaville, is a country in Central Africa with tropical forest reserves that are home to gorillas. Its capital Brazzaville faces Kinshasa, the capital of the Democratic Republic of Congo, on the other side of the Congo River. The Republic of Congo is located in Central Africa. The bordering countries are Gabon to the west, Cameroon to the northwest, Angola with the enclave of Cabinda to the southwest, the Central African Republic to the north-northeast and the Democratic Republic of Congo to the east and south. The Congo River, the second largest river in the world by average flow after the Amazon, forms part of the border between the Republic of Congo and the DRC. The tropical rainforest covers nearly two-thirds of the territory of the Republic of Congo23, making it the fifteenth country in the world by the proportion of forest cover. The equator crosses the Congo; its passage through the city of Makoua, in the Cuvette region, is marked by a boundary stone. The country has a maritime coastline on the Atlantic Ocean with a length of 220 km. With just over five million inhabitants, Congo-Brazzaville is a country with a low population density, with an average of 13 inhabitants/km2; the only less densely populated countries in sub-Saharan Africa are Gabon, the Central African Republic, Chad, Mauritania, Namibia and Botswana. The majority of its population is urban (62.2% of the population); it is concentrated in the two main cities of the country, Brazzaville and Pointe-Noire, located in the southern part of the country. We can speak of "macrobicephaly24", Brazzaville and Pointe-Noire have respectively approximately 1,700,000 and 1,200,000 inhabitants, while the third city of the country, Dolisie, barely reaches 200,000 inhabitants. The urban fabric is very sparsely populated, with about fifteen cities of more than 10,000 inhabitants for a territory of 342,000 km2. The rural regions of the south are relatively densely populated (between 5 and 40 inhabitants/km2), the maximum being reached in the region of Boko (Pool) and the surrounding area. On the other hand, the northern part of the country can be described as a human desert, with densities most often between 0 and 2 inhabitants/km2, particularly in the marshy regions of the northeast.
