The Minister of the Colonies, in accordance with the plan of the Central office of the Construction et d’Étude du Matériel ferroviaire (OCEM), has instructed the Société Alsacienne de Constructions Métalliques (SACM) to build for the non-conceded networks of Indochina [Chemins de fer de l’Indochine, CFI], 15 new steam locomotives of the “Pacific” type, 15 tenders and related replacement parts.
These machines will have a boiler pressure of 16 hpz/bar.
Their coupled driving wheels will be 1.400m in diameter. Their total operating weight will reach 60.200kg, and their adhesive weight 39.000kg, or 13.000kg per axle. But it will be reduced to 11.000kg per axle. The two front bogie axles will carry 6.7 tonnes, and the rear bogie axle 7.8 tonnes.
The tenders will have twin two-axle bogies; their gross weight in service will be 36.400kg and their capacity will be 16 cubic meters of water and 6,000kg of fuel.
The coupling between locomotive and tender will be of the Eastern type, with central bar and spherical ball-joint.
The locomotives will be able to haul trains on flat, level areas of track at a speed of 55km per hour.
They will normally be able to reach and sustain, while hauling a passenger train of 250 tonnes on flat, level areas of track or on gradients of up to 3m per 1000m, the maximum speed permitted on the CFI network of 90km per hour.
The magazine Les Chemins de fer et les Tramways believes that the commissioning of these machines will probably accelerate services on the 1729 km Transindochinois route from Hanoï to Saïgon, a route which currently takes 40 hours and 20 minutes at a speed of 43 km, the 97km stretch from Thuan-Ly to Dông-Ha being covered in either direction without stopping in 1 hour 46 minutes at a speed of 55km.
