Data from Bruce (1952); "American Design of Consolidation Type Locomotive for the Belgian State Railways", Railway and Locomotive Engineering, Volume XXXIII [33], No 4 (April 1920), p. 105-106; and "American-Built Locomotives for the Belgian State Railways", Locomotive Magazine, Volume XXVI [26] (15 May 1920), pp. 96-97. Works numbers were 61620-61694 in 1920,
High-pitched, plain boiler and three-axle tender give this design a European, utilitarian look. The Belgian railway system had been devastated in World War One by the offensive sweeps and trench-bound stalemate that lasted four years. Several builders were called upon to supply a basic 2-8-0 design and both Alco and Baldwin (Locobase 14593) responded. Both US builders fulfilled the same specification, but Locobase has separated the two orders (for 75 locomotives each) because of the slight differences in heating surface areas. Measured from the fire side, the tubes and flues offered 1,276 sq ft (118.54 sq m) in heating surface area. The firebox heating surface area in these Alcos included 1.6 sq m (17.22 sq m) in arch tubes. Armstrong-Whitworth produced 200 locomotives for the Belgian State in the same year; see Locobase 20371.Data from DeGolyer, Vol 57, pp. 209. Works numbers were 53005, 53029-53033 in February 1920; 53070-53074 in March; 53083-53090, 53109-53118, 53129-53134, 53149-53156, 53166-53172, 53190-53193 in April; 53218-53224, 53242-53245, 53261-53265 in May; 53273-53275, 53297-53298 in June.
High-pitched, plain boiler and three-axle tender give this design a European, utilitarian look. The Belgian railway system had been devastated in World War One by offensive sweeps followed by trench-bound stalemate that lasted four years. Several builders were called upon to supply a basic 2-8-0 design and both Alco (Locobase 5045) and Baldwin responded. Both US builders fulfilled the same specification, but Locobase has separated the two orders (for 75 locomotives each) because of the slight differences in heating surface areas. Baldwin's specifications say that all drawings were to be made in the metric system. The Baldwin specs say that the maximum grade on the system would be 3.3%. The specifications also show that these engines used relatively large 305 mm (12") piston valves to serve the cylinders, which were larger than the Pershings on which the Belgian design was based. Indeed, Belgium's engines also benefited from longer tubes and flues and a larger firebox.Shown in an Alco advertisement in the 1947 Locomotive Cyclopedia. Similar to many other engines built by American companies and exported to many other countries after World War II. See Locobase 950 for China's KD7.
