Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . heless, been several very im-portant and significant electrifications that have stimu-lated the development of the electric locomotive and indi-cated world-wide interest in electrification. In spite ofthe poverty of the war-stricken countries in Europe, rail-way electrification is progressing or under active discus-sion in nearly all of them, stimulated in most places bythe high cost of coal and the possibility of rising waterpower. Two large installations are being made in SouthAfrica: two or more in South America; Australia is inthe market for additional electric-railway equipment; andothers are progressing in the East Indies and Japan. The principal new locomotives in which the companytin- author represents has had a part are listed, with theirprincipal dimensions, weights, type, in Table 1. Paulista Railway Locomotives . Two types of Baldwin-Westinghouse locomotives werebuilt for the Paulista Railway of Brazil, as shown inTable 1. The freight locomotive has six driving axle?. Fig. 1—Central of Paulista Passenger Locomotive contained in two articulated trucks. Each axle has a mo-tor geared directly to it. The motors are wound volts each and are operated with two or more inseries at all times. There are three combinations of mo-tors: first, six in series, giving one-third speed; second,three in series, two in parallel, for two-thirds speed;third, two in series, three in parallel for full speed. Thereis in addition a higher speed in each combination, obtainedby tapping the fields of the motors. Regenerative brak-ing is obtained at all speeds with full power. In speed combinations the control system follows theprecedent of the Baldwin-Westinghouse locomotiveswhich have operated so successfully on the Chicago. Mil-waukee & St. Paul Railway, but the control in simpler than that of the Milwaukee locomotives becausethere is neither train li
