Themaximum tractive effort based on 25 percent adhesion will be 40,000 pounds. The Road Freight Locomotives The cabs for the first eight of tlie fif-teen road freight locomotives have beendelivered by the Baldwin LocomotiveWorks to the Westinghouse Electric SManufacturing Company for the installa-tion of the equipment. There will also beseven switching locomotives. An outline of ^he road locomotive isshown in an accompanying cab is of the box type, carried ontwo articulated trucks, each having threedriving axles with direct geared estimated weight is 226,000 locomotives will operate at 3,000volts direct OlTLTNE OF ROAD FREIGHT ELECTRIC LOCOMOTIVE FOR CHILEAN STATE RAILWAYS. common frame for both motor and gen-erator.
