Rural lines

The rural lines were operated by a separate company, Compagnie des Chemins de Fer de la Plaine du Cul-de-Sac (CCFPCS) but the two companies shared their rolling stock. The track gauge, in both cases, was 30 inches (762 mm). There were two routes:

* Port-au-Prince to Léogâne (36 km)
* Port-au-Prince to Manneville (43 km)

Following the US occupation of Haiti in 1915 the CCFPCS was taken over by the Haitian American Sugar Company (Hasco) and re-named Chemin de Fer Central. Hasco used the following locomotives:[2]

* one 32 ton 2-6-0
* one 36 ton 2-6-0
* one 15 ton 0-4-0
