The calculated tractive force of these locomotives is 108,300pounds and in this respect the design marks an advance overany engines heretofore constructed by the builders.

Although they arein some respects an experiment, the previous experience of thebuilders with heavy articulated compound locomotives indicatesthat their performance will be satisfactory.
