TRAIL CAR BRAKE SHOE (A J-13) motormen to make a much quicker stop without skiddingthe wheels than was possible with the other types of con-troller, or with any form of power brake. The diagramon p. 138 shows the development of the controller and theconnections of the apparatus for both power and brake. It will be observed that the brake shoe on each axle isdirectly in series with the armature of the motor on thesame axle. If either brake tends to lock, due to a too rapidapplication of the brake, the axle will cease to turn, or, atleast, slow down, with the result that the armature in serieswith the shoe ceases to generate as great a voltage as thearmature of the other motor. The natural result is, that current will pass through thelocked shoe in the reverse direction and demagnetize it,allowing it to release. As this action is entirely automatic, it is practically impossible to skid the wheels for morethan a foot or two, which is not sufficient to cause a flatwheel. The maximum braki
