the adventures of Bamboula

One can imagine the Politically Correct brigade looking askance nowadays at this bande dessinée series from the 1950s, particularly as the languefrancaise.net website gives the definition of Bamboula as "Surnom générique de Noir, Noir, Nègre" (generic nickname of black, negro). Mat was the pen name of Marcel Turlin (1895-1982).  The locomotive in the first picture seems to be based on the SNCF 9100 class.
