A barframe of Prussian origin is constructed at Hannover for the 00 00 0type balanced compoundengines of the DanishRailways. This barframe weighs, complete,6140 kilograms. It hasfour cylinders, served bytwo piston valves whichare so placed that a vari-able ratio of cut-off isnot possible between thetwo valves as in the Ital-ian locomotives, whereeach valve has its ownreversing gear to adaptthe engines to extremevariations in the condi-tions of service.

JJelgium whieh had for a number of years relin(]uislied initiativein the matter of locomotive design and had imported Scotch plans ofScotch engines, began building modern engine types in 1904 and thefinest specimen, known as Type 19, is of the Central Europeanbalanced compound arrangement with cylinders all exactly in lineand driving on one axle only—the boiler being the plain simpleScotch type without superheater. Constructively, the engine is of thesame disposition as Nos. 3302 and 3303, balanced non-compound en-gines. Figure 48, one of which has a superheater in the boiler tubes,[n these latter, the rocker drive for the outside piston valves is similarin principle, if not in construction, to the gear Mr. Webb applied tohis first four-cylinder balanced compounils.
