Taking into account the fact that a speed of 200 km. perhour was contemplated, it was arranged to provide, in additionto the Westinghouse air brake, an electrical brake which couldbe used either in connection with, or independently of, thesource of current. The brake was so designed that it could beapplied either gently or powerfully, at will. 312 AMERICAN ENGINEER AND RAILROAD JOURNAL. f/^£S^T 11 **—•... • *A\f ■ • ■ &■*—•—• ■«—vsj • •^■j! • • • • f-rr-r-— n - y-1 1. 3r V ■•> * I l^la C/3. o w — 3 C o
