The rack motor runs on no-loadand maintains a constant speed, which is approximatelythe same as that of the adhesion motor. By this meansthe locomotive can run on to the rack even at highspeeds without any injurious vibration. The synchron-ism between the loaded motor and the rack motor run-ning on no-load is obtained by connecting the field ofthe rack motor in series with the field and armature ofthe adhesion motor, the armatures of the two motorsbeing connected in parallel. The factors which deter-mine the speed are therefore the same for both motorsif the pressure drop and armature reaction are left outof consideration. On the rack section the motors workwith the usual series-parallel connections, the motorsbeing in series on the first nine steps and in parallelon the remaining six steps. On the ninth and fifteenthsteps the motors are shunted. By
