. American engineer . with but minor alterations, asthe service demanded. During 1911 and 1912 changes were madein all designs which had not been previously fitted with theWalschaert valve gear, and this gear is now standard on all loco-motives with the exception of the consolidation and Atlantictypes. The boilers have been arranged to permit the applicationof high degree superheaters in practically all classes that are nowbeing built. The common standard types of locomotives at present are intended for special work in certain districts. The most notice-able of these is the lignite burning Pacific types of the OregonRailroad and Navigation Company and the balanced compoundAtlantic types for the Union Pacific. During 1912 one hundred and fifty-six locomotives were builtfor the Associated Lines by the Baldwin Works, and forty by Locomotive Company, all of them being of the modi-fied and present standard for each type. These consisted of 36switching locomotives; 55 freight Mikados; 10 passenger. IVlogul Locomotive Witli Superheater for the Associated Lines. therefore the original Atlantic and consolidation types withStephenson valve gear and without superheaters; the originalsix wheel switching type to which the Walschaert valve gear hasbeen applied; light and heavy Pacific types with Walschaertvalve gear and superheaters; two classes of ten wheelers, onefor oil burning with a narrow firebox and the other with a widefirebox for coal burning, the latter being built with either 63 69 in. wheels, but without other change (both of these havesuperheaters) ; a mogul which is the original design with the Mikados; 55 Pacifies; 15 moguls; 10 ten-wheelers and 15 Malletsof the 2-8-8-2 type. The general dimensions of these locomotives,as well as the latest design of the 2-6-6-2 type, are given in theaccompanying table which by the comparison with the dimensionsas given on the original locomotives to be found in the AmericanEngineer, as noted, will show what alt
