The coils are all alike and inter-changeable, so that injured ones may be replaced with ventilation is provided for the interior of the armaturecore, and air ducts leading to the surface aid in keeping up agood circulation. The high-grade steel from which these coresare made insures low hysteresis losses, and the thorough insul-ating of the laminae from each other prevents the formation ofeddy currents. The commutator is very large and has many bars,rendering the commutation perfect, even with an extra heavyload on the motor. The brushes are in two sets at the top ofthe commutator, with two brushes in each set. No sliding con-tacts are permitted to carry current, each brush being fitted witha brass clamp which moves with it, and a flexible braided ribbon shocks at the rear joints and cross-overs. The motors are car-ried on each of the two end cars of the train. The controllingmechanism is in many respects s
