The following article will dealwith the problem as affecting the MALLET COMPOUND LOCOMOTIVE FOR REGULAR FREIGHT SERVICE—GREAT NORTHERN RAILWAY. MALLET COMPOUND FREIGHT LOCOMOTIVE. Great Northern Railway. The Baldwin Locomotive Works is delivering an order oftwenty-five Mallet compound locomotives to the Great NorthernRailway which are of special interest as being the first of thistype to be put into regular road service in this country. It will beremembered that this railroad received five locomotives of thesame type from the Baldwin Works last fall,* which were de-signed for pusher service in the mountains and have been givingmost satisfactory results in that capacity. This later order being designed for different service, naturallydiffers from those now in use in many respects. They are lighterin weight, have smaller cylinders, a much smaller boiler and asomewhat shorter wheel base. In the general features and ar-rangement of parts, however, the two designs are very muchalike. The accompanying table wi
