The train service from Souk El Arbaa to Oued Metlili is primarily served by the ONCF (Office National des Chemins de Fer) conventional trains. These regional trains offer standard seating options and fairly comfortable travel for passengers. Travel times between the two towns average around 4 to 5 hours, depending on the specific service. The trains typically operate at speeds ranging from 60 to 100 km/h (37 to 62 mph), as this route is not covered by high-speed trains, which are more common in larger urban connections in Morocco.
Passengers can expect basic amenities on board, including standard seating and restroom facilities. While these trains may not provide the same level of speed as high-speed rail services, they do serve the important role of connecting smaller towns and cities. The journey is scenic, allowing travelers to experience local landscapes, though timing should be considered as the trip can be longer than other main routes.
