Grand Central Articulated Locomotives in Belgium

Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 3597)

Data from W H Maw and William Dredge, "Locomotives", Reports on the Vienna Universal Exhibition, Part II (London: George Eyre and William Spottiswoode, 1874), pp. 412-416. See also Hippolyte Fontaine, Description des machines les plus remarquables et les plus nouvelles a l Exposition de Vienne en 1873 (Paris: Libraire Polytechnique, H Baudry, Libraire-Editeur, 1874), pp. 391-399. See also Reder (1974, p 257), Wiener (1930).

Like L'Avenir, the Gunther-Meyer engine that had failed to impress five years earlier, this articulated's career was short and undistinguished. The design two engine sets under a single boiler with the cylinders grouped under the center and the drivers at each end of the frame. See the long analysis in English in Maw and Dredge and in French in Fontaine with Maw and Dredge comparing the Meyer design unfavorably to Fairlie's double-bogie design in many respects.
